The goal of this section is to take you beyond the Educaching realm and give you other interesting ideas to implement with your students, and maybe even spark some creative ideas of your own. Note: These ideas are not all original! Many have been borrowed from great teachers and others who are already out there “caching” away!

CITO
     This acronym stands for “Cache In, Trash Out” and is a healthy way to encourage a little environmental etiquette. The basic idea is that while you are out EducachingTM, you carry a small garbage bag to fill with trash. Place a small plastic grocery store bag or kitchen garbage bag into 35mm film canisters. Pass these out to students before a hunt and instruct them that they need to place any trash they find into the plastic bag and dispose of it properly when back inside the building. Explain to your students that they have a responsibility to their community to keep things cleaned up, and that this is an easy way to practice.

     You can also set up a specific CITO hunt in your schoolyard. Give groups the different waypoints of areas that need to be cleaned up (i.e. playground, north end of building, playing fields, etc.). Set a time limit, then have them meet back at a central location. The central location coordinates could lead them to the school’s dumpster! Then give final coordinates for them to find a cache holding a treat for them as a reward for all their hard work. You could team up with the school’s student council for this activity, or branch out into the community with some help from parents to organize a larger CITO event. See www.caceintrashout.org for information about the actual organization.

Out Into The World
Here are a couple ideas to help your students make connections with the communities, and even the world surrounding them:

Travel Bugs – A travel bug is a trackable item that can travel all around the world through “geocaches” that people have hidden. Travel bug dog tags or other trackable signature items can be learned about and purchased online through www.geocaching.com.    A recommendation is that you purchase a few of these and send them off on “missions” throughout your school year. The students can track a travel bug’s progress online and read logs posted by people who pick it up and drop it off in another location. The beautiful thing is that the travel bug can continue to circulate the globe long after it is released by your class. A student will be able to continue to see where it goes and where it has been long after you teach him or her. 

     Try thinking of unique mission for your travel bug. For example, the goal of the travel bug EduBee (go to www.geocaching.com, click on trackable items, then use tracking number: TB1CF4P), is to travel to educational institutions all over the United States and learn interesting facts from people who find it. The 5th grade class that sent this travel bug can then learn facts from people all over the U.S. and learn the geography about where the bug has been. Here’s another idea: let’s say your class is going to be studying volcanoes. If you can’t take your class to the nearest mountain of magma, send a travel bug with a mission to photograph a particular volcano, then you and your students can research that volcano and its surrounding area! What other travel bug ideas do you have that could allow your students to “travel” the world?


Postcards
     Hide an Educache container on or near the school grounds or somewhere in your community and log your container at www.geocaching.com. This will allow for anyone in the world to
locate it and log their find online. Make certain you hide this container according to the web site’s requirements. Inside the container, place blank postcards addressed to your school, care of you and your class. When someone finds the container, they will take a postcard, fill it out with information regarding where they’re from, and send it back to your school. 

     Won’t it be fun for your class to receive mail from fellow “cachers”? For more fun keep track on a map of what parts of your county, state, or other country you receive them from. Students can create a US (or world) map on a bulletin board or wall and then attach the postcards on the map.
     Over the course of the school year, the students can keep track of the locations. Postcard senders will tell where they are from and a little about the area in which they live. You could have students calculate distances: furthest traveled, closest in proximity, etc., as an extension.


Well, that's a few for now...more "beyond" ideas to come! Feel free to post your own in the comments section. Until then, keep 'em caching!

1,000,000!

The Geocaching Blog announced recently that America has hit a milestone...one million geocaches placed in the United States! So, what are you waiting for? Get out there caching and get better ideas to use with your students!

Back To School with Geocaching in Education

Hey Everyone,
Welcome back to school! If you're anything like me, you are up to your eyeballs in SLOs, TBTs, and every other educational acronym under the sun. A new year is upon us and we have a wonderful new class to enjoy teaching. Getting bogged down by the pressures and stresses of the school year can easily cause us to lose sight of the fun in learning...so, why not try taking your students outside this fall and get them searching for caches?!

Here are a few websites/ideas to get your engine jumpstarted...

Geocaching with Kids: Tricks of the Trade

This post is from the official Geocaching blog and can be found here. Maria McDonald does a nice job here of tips to successful caching with Jr. High students.

Geocaching: Middle Schooler Tested and Approved

By:  Maria McDonald.

A new generation discovers the GPS device.

As a Geocaching HQ staffer often tethered to the office, I love it when the opportunity to be out in the community presents itself. Such an opportunity presented itself last week when a teacher (Username: Cache-alope) from a local after school science program (Pathways) asked me and Partner Programs Manager Annie Love (Love) to present geocaching to her middle school students. My immediate reaction: Middle schoolers?!? Oh no…anything but the awkward tween years. Luckily, my love of all things geocaching overcame these initial thoughts, and the opportunity to share my passion for geocaching with the next generation removed any lingering doubt.

While preparing our presentation, I got to thinking about children’s involvement with geocaching more generally. While one of the most fascinating elements of geocaching is its ability to be many different things to many types of people, children have a particular place in this game we cherish. First and foremost, kids love toys. If nothing else, geocache SWAG gives youngsters the opportunity to find fun toys. This often keeps them interested in a ‘treasure hunt’ before the more nuanced elements of the game can hold their attention. Another element that particularly appeals to children (or rather to their adults chaperons) is the idea of giving their walk a purpose. Have you ever tried talking a child into going for a walk with you? Nearly impossible! They’re bored and whining before you hit a quarter mile. Tell a child you’re going geocaching and you can get her to cheerfully – and unknowingly – go for a long walk. Lastly, I thought about the importance of finding activities the entire family can enjoy. Geocaching has wide appeal in this aspect as babies in strollers, grandparents in walkers, and every age and stage in between can find something about geocaching they enjoy with geocaches they are able to access. It truly is an adventure for the whole family.

So how do you get your youngsters into geocaching? Here are 5 easy Tricks of the Trade (TOTT…but different this time around).

1. Bring Snacks. Simple but true, you can bribe – I mean convince – a child to do just about anything with the right snack as incentive.

2. Be enthusiastic. Kids know fun when they see it. If you see geocaching as something fun, adventurous, and exciting, that enthusiasm is going to shine out your face like rainbows and they will want to be part of the action.

3. Plan geocaching outings that you know will provide SWAG. This part is easy, as mentioned earlier children love stuff. Geocaches have stuff in them. Plan on searching for geocaches with young ones that you know will provide them with cool stuff. Worried the geocache may not have the goods needed to keep your child’s attention? You’re an adult – use your super sneaky adult powers to have extra SWAG of your own on hand to suddenly make SWAG ‘appear’ as if from the geocache itself. Sort of like planting evidence but much more legal. After the planted SWAG is discovered enthusiastically, mention the next geocache with cool stuff is just around the corner…

4. Find caches that match the child’s skill set and ability. At every age of child development there are markers and goals for what children are capable of learning. Find a way to incorporate the learning goals for their age range into the caching experience. Think broadly about what this could entail, are they working on balance? Climbing? Counting? Over/under/up/down differentiating? Find the skills they seem naturally drawn to learning in their age range and work them into the adventure.

5. Make them part of the team. Children of any age, much like all other ages of humans beings, want to be included. When children are able to participate and contribute to something they see others doing with enthusiasm they will want to play a role themselves.

Hunting in the rain for the geocache… and SWAG.

So how did the presentation with the dreaded middle schoolers go? Amazing. This was the greatest group of youngsters you could ever hope to geocache with. They were riveted by the geocaching presentation and remained two steps ahead of us with every engaging question. When it came time to leave the classroom and enter into the woods on this particularly rainy day, the kids charged ahead brimming with enthusiasm. The students worked together in pairs, one using a compass and the other piloting a GPS heading towards a staged geocache their teacher had placed specifically for them. They worked their way quickly towards the find and made up usernames on the spot when signing the staged logbook. How “XXthekillertacoXX” came so quickly to one young lady’s mind I’ll never know, but a greater username I challenge you to encounter. The adventure came to a close upon returning to their classroom where the students excitedly talked about how they could share this fun new activity with their families. This afternoon in the woods with youngsters reminded me that Geocaching really can be fun for all ages, even tweens when presented correctly.

Geocaching and Education, part 13 - Caching Management

To reinforce again some important information from a previous blog post, I have decided to discuss here management of caches. 

Preparation

Any Educaching lesson will require preparation, just as any lesson you would teach in your classroom. You will have to prepare educaches, hide them, mark waypoints, keep track of equipment, and so on. Start slowly and work your way up to more difficult types of hunts. Make maps of your schoolyard and where your great hiding spots are, along with their waypoints, and keep them! The more experience you have with your GPS unit and with hiding educaches, the more comfortable you will become and the easier and less time-consuming the preparation process will be. Noted below is a small list of preliminary work you should only need to do one time.

It is necessary to:

1. Discuss caching with your principal and obtain permission. 

2. Take a copy of a map outside with your GPS receiver. For your map, sketch the layout of your school campus, including buildings, fields, playgrounds, trees, shrubs, signs, and other pertinent landmarks. This could  also be a printout of a satellite image overhead of your schoolyard area.

3. Mark or highlight the areas that would make the best hiding spots for items. Pretend you are hosting an Easter Egg hunt. Where would the best spots be for your students? You want the items to be hidden, but you don’t want them impossible to find. Never bury something. Rather, conceal it with mulch, stones, etc. to “camouflage” it from view.   

Here are a few ideas of some good hiding spots: 

Trees – especially in the knots, holes, or forks where branches spread out, but do not make them climb for it.

Shrubs – at the base or nearby...maybe you can use a little mulch to help camouflage something at the base of a shrub

Buildings – Anywhere along the perimeter of your school building would be an appropriate place. Landmarks – School signs, playgrounds, flagpoles or other “significant” spots on your school campus

Once you have a map of your schoolyard with good hiding spots in mind, you will be ready to begin one of the Try This First! activities in the Educaching manual. These will be offered in subsequent blog posts. 

Educaching in the Primary Grades

Recently, a fellow educator inquired about how to best begin caching with her 1st graders. First off, let me say, what a bold teacher! Having mostly taught caching with 4th and 5th graders, but having also taught K-5, I admire anyone who wants to put this great learning technology into their younger students' hands!

So, if that describes you...hang in there and do your research! Here are a few ideas to get you started: 

The best thing to do with primary students is to first acquaint them with the GPS receivers, cache containers, and how to do a basic search for a cache container. From there, you can build on what they know and adapt practically everything in your curriculum to meet student needs and take them on hunts.

If you have the Educaching curriculum, you can familiarize your young students with how to begin by going through the Try This First! lessons beginning on page 13 of the manual. GPS Club is also a great way to springboard into Educaching with your students. It is a great introductory set of activities, is objective-based, and even includes a pre/post test.

I found some other discussions/resources online that may also help (listed below) or you can always search this blog.

1. Geocaching for First Graders on the Groundspeak Forums

2. Here's a helpful powerpoint slideshow that gives ideas for primary and upper grades.

3. An article on connecting Geocaching to literature...could be done by pairing your primary students with older children or by having adults help.

4. How to teach Mapping and Orienteering to young children

5. Here's a wiki that shows pictures of primary students caching, what they found, and what they did with those things back in the classroom.

If you have other great resources to teach caching to young students, post a comment here!

STEMlandia! The Nature's Apprentice Geocaching Adventure

So if you are in the Boston area over the next month or so, you have to check out this Geocaching Labs event! It is a chance to explore an arboretum while geocaching and better understanding the importance of S.T.E.M. (Science, Technology, Engineering, and Mathematics). Even if you cannot attend, be sure to follow the link and check out the geocaching passport below, as they are sure to give you ideas for interesting S.T.E.M.-related hunts you could create in your own school's area!
Enjoy,
Jason and The Educaching Team

Printables!

As we near the "Ides of March," there's no need to beware. Unless of course, you are talking about another snow day for teachers in the Midwest states like me! I never thought I'd say this, but I don't want another snow day cancellation from school. Seriously, this makes about 14 for us. Anyway, as winter draws to an end, it usually signifies the opportunity for the caching teacher to really be thinking "outside activities" for students. For me, many a spring cache hunt was ruined for my students and I by the spring rains. That doesn't mean you can't gear them up for what's to come, however. Here are a few printables you may want to use with your students this spring to get them excited! (The placemats would make great desk-toppers for some morning work!)
These great resources are from Geocacher University.

Happy New Year! And Happy 10th Anniversary to Earthcaching!

Happy New Year everyone! I hope that 2014 is a blessing to you and all whom you teach!
Today, I received the following email from geocaching.com. It seems that Earthcaching is celebrating a birthday! Since Earthcaching is such an educational experience, I felt it a great connection to educaching. If you have not already, watch the linked video, then try an Earthcache of your own...who knows what rich geological treasures await you and your students nearby your school!

"For a decade, EarthCaches have delivered adventurers to the tops of mountains, to strange and unusual rock formations and into the steaming, bubbling processes that created the Earth—all without a geocache container. Instead, geocachers must use their geological detective skills to uncover the answers to specific questions about the location.

EarthCaching in 6 Bullet Points:

• 16,600 active EarthCaches worldwide (there's probably one near you)
• The first EarthCache was published on January 10, 2004
• Partnership with the Geological Society of America
• Found more often and receive more favorite points than average geocaches
• There are more than 100 events worldwide celebrating EarthCaching’s 10 years 

Join the celebration! Watch this video*for an EarthCaching experience, then go out and find one of your own."

*Note: NO cache containers were harmed in the making of this video.

Happy New Year,
Jason and the Educaching Team

The Educaching Geocoin travels!

Well, it may not have traveled far (only 875 miles) and it may not have made it to many states in America yet (only 3), but the Educaching Team is still proud of our little guy! The first official Educaching Geocoin has been rounding our little midwest area over the past couple years ever since it was born.

Learn about its travels here.

Being passed from cache to cache by ever-vigilant geocachers, travel bugs and coins like ours can really rack up the miles while making it fun for cache finders all over. The gist is to move them as soon as you find them!

Here are the links to a couple more travel bugs of mine that have been a little more successful in their travels (although they are lost now):


Emily's Egyptian Bug
Goal: The mission of this travel bug is to take a tired, worn-out camel to Egypt where it belongs. A class in Ohio is watching its whereabouts, so please move along soon. Please take pictures of my journey along the way! P.S. I need to get to the great pyramids!
Current Status: Missing in action
Distance Traveled: 1,166 miles




Ben's Italian Bug
Mission: The goal of this bug is to travel as far east as possible this year from Ohio. Its end goal is to reside in Rome, Italy. Please send on quickly, as some 5th graders are eager to see its travels this school year. Take pictures, too!
Current Status: Also missing

Distance Traveled: 1,643 miles

In a previous post, I featured an activity page for you to use with your students to brainstorm ideas for a travel bug/geocoin's mission. Feel free to copy and use this as you wish (see below), and good luck in your endeavors to send out your own trackables! For more information on trackables, visit here.

Geocaching and Education, part 12 - Absolute and Relative Location

This is post #12 in a series of free resources for educators interested in using geocaching in education and other community groups like scouts or camps.

Absolutely Relative or Relatively Absolute – This activity allows your students to understand the difference between absolute location and relative location. Absolute location is what we use to describe an exact location. For example, 27979 White Road, Perrysburg, OH 43551 is an absolute location. Absolute location can also be found using waypoints in a GPS receiver---it is an exact spot on the map. Relative location involves a slightly less precise way to locate something, but we use it all the time. When we are telling someone how to find a gas station we say, “It’s two blocks down, then turn right, go over the railroad tracks and you can’t miss it. It’s beside the post office.” Relative location is described in great detail through the use of distances, directions, amount of time taken, and landmarks along the way. This is an important activity, because your students will be employing skills in both when they are Educaching. For example, when on a hunt, they use absolute location (coordinates) to find an Educache’s spot, but will also receive clues using relative location (i.e. under the rock, beside the tree, about 300 feet from the front doors of the school, etc.). Let’s use Educaching to teach the concept to your students by setting up a hunt that requires them to use both. To make things simpler, this will be a group hunt similar to the activity on Day 1. You will hide two Educache containers. The first one will be a small container with a set of directions inside to get to the second Educache. The students will use coordinates and their GPS to get to the first Educache (absolute location) and descriptive directions to reach the second (relative location). Find a hiding spot for the first Educache, then from that spot, look to see where you will place the second. Be creative! How can you describe how to get there? For example, will the students count paces? Will they head in a specific direction, like Northeast? Will they look for any signs or landmarks on the way? Try combining several of these clues to get the group from the first Educache to the second. Test out your directions by walking the path to your second Educache spot. Write these directions down and place them in the first Educache container and hide it in the first spot. Be sure to mark the waypoint in your GPS receiver to give the students these coordinates. Then, hide the second Educache in its spot containing a rewarding message to congratulate the students.On the day of this hunt, explain to your students the difference between absolute and relative location and have them give examples. Explain that they will use both in Educaching. Group your students so that they can share the GPS receivers, and give them the coordinates of the first location to input in their receivers now. Take the students outside and seek the first Educache together. When it is found, choose a student to open the container and read the directions one step at a time as the group follows the directions. Note: You may have to explain what a “pace” is if you used the word in your directions. Usually a pace is the distance covered by one step, or approximately three feet. Work as a large team to follow the directions carefully to the second Educache. The students may find that they need only to use the GPS to find compass bearing. As long as they are moving, the compass pointer on the GPS receiver will tell them the direction they are heading. When the students reach the area of the second Educache, tell them to look around for any good hiding spots where it might be. When it is found choose a student to open it and read the message inside. Before finishing this activity, review how absolute and relative location was used in this hunt. Also, see if the students can use their GPS receivers to calculate the distance between the two hidden educaches. Measurement is a vital skill used in most of the math lessons, and this would be a great point to have a mini-lesson on the topic.As a variation, you may want to have each small group look for its own educaches. This will require more preparation on your part, but will lead toward student independence. In this case, bring the students inside the classroom immediately afterward to discuss their successes and challenges with finding their educaches.

Geocaching and Education, part 11 - A breath of fresh air...Two Quick and Fun Activities

Tennis Ball Madness - Give each of your student groups a tennis ball and a GPS receiver. Have the groups go out into the schoolyard to hide their tennis ball and mark a waypoint at the location of the ball. Give them a time limit and assist them with their receivers if needed. The students then return and give their GPS receiver to another group who uses it to go find the ball. A tennis ball, or plastic Easter egg if you prefer, provides an easier to find cache that will be a little easier to find. This activity gives students practice in mastering the GPS functions, especially in marking (saving) waypoints.

Grab It And Go – This one is very similar to the activity above, but is more of a relay. Give each team an object (i.e. golf ball, craft stick, action figure, etc.) and a GPS receiver. Each team hides their object, marks the waypoint in the receiver, then return. Teams trade receivers, then when you say “GO,” all teams find the other group’s hidden object, grab it, and race back to you as fast as possible. The team that makes it back first, wins! If you want to add another skill to this, give each group a map that they must mark down their object’s location on, along with the waypoint. Then, when they go find the other team’s object, they must also draw its location on their map, along with the waypoint before they bring the object back to you for the win. With younger students, this can be a great way to review cardinal directions and basic map skills. It is also a great way for ALL students to get some exercise!

         This activity is highly recommended as it will serve as a way to do more class instruction, while giving your students more independence. As preparation, you’ll need to hide about 7 containers. Try to make a few of the containers different sizes; some film canisters, some small Tupperware, some shoe box-sized. The reason you are doing this is so the students understand that not all Educache containers look alike, especially in size (i.e. You will not be hiding film canisters all the time!). Place within each container a simple math problem or a fun trivia question. Make it something that they can answer without too much difficulty. Hide each one carefully and mark the waypoints of each with your GPS receiver. You may also want to bring along a teacher map and mark the location and waypoint of each one for your reference. Write down each waypoint on a scrap of paper and put them in a hat for students to draw from on the day of your hunt.
          Okay, let’s go Educaching! Assemble groups and have each group choose one piece of paper out of the hat. Inform them that this is the waypoint for the educache they need to find today. This is a great time to introduce and assign the group roles of Navigator, Scribe, Reader, and Photographer (optional). Pass out the GPS receivers (and any instructions you may want) and have each group input their waypoint in their receiver, reviewing with them how to do this. Remind them to double check their coordinates!
          Now take the groups out to a central meeting spot in the schoolyard. Give them specific instructions that they are to use their compass pointers to find their educache, just as they did before. When they find it, they are to open it and solve the math problem or the trivia question inside. They then replace the question inside the container and bring the container back with them to the central meeting spot. Give your students a time limit you deem appropriate (10 minutes ought to be plenty of time). Assist any groups as needed with the equipment, but resist giving them the answers. Instead, ask questions like, “What do you think?” or “Which button would make the most sense to press now?” Encourage teamwork, but help them become independent from you and do not solve the mystery for them. Be sure each group finds their educache. Some students that finish early might be very willing to help another group that is experiencing trouble. This promotes a larger sense of teamwork in the class.
           When all groups are finished and back at the meeting spot, have each group show their educache to the other students. Have them open it, read the problem or question, then give their answer. Encourage teamwork among the class by having everyone clap for each group’s success. Even if they don’t get the answer to the question right, each group still was able to use the technology and with careful observation correctly locate their educache. Close this activity by reviewing terminology, features of the GPS receivers, or answer questions. You may even want to introduce the sport of geocaching and discuss the possibility of hiding an educache for others around the world to find, or to introduce the concept of CITO. When finished with the activity, have the students bring all materials back inside the building. See the Beyond The Basics section of the Educaching curriculum for these ideas and much more! 

Putting Waypoints on Multiple Receivers

For a large set of receivers, if you want to quickly put your waypoints on all of them, you have to have the right software. There are several free options, which, depending upon your tech-savviness, may take a bit of practice and finagling. Depending upon your type of receivers AND your type of computer, you may find the following useful:

For Garmin GPS receivers: Garmin BaseCamp - This software is free and is available for PC or Mac. Garmin BaseCamp will allow you to upload waypoints from one receiver to the program. Then, you can easily change the names of your waypoints, organize into hunt lists (i.e. Golf Ball Hunt, Madison Elementary Autumn Cache event, etc.), and hook up each individual receiver after that in order to download to all of your units.

For Magellan GPS receivers: VantagePoint - This software works much like Garmin's BaseCamp, except it is only available as a PC download. So if you have a Mac computer and you use Magellan units, I have used MacCaching free software and it works well.

For Geomate.jr receivers: Go here to sign up for a free account. Then download what you need for your PC or Mac here. From that point, you use the Custom Cache tab to upload waypoints from one Geomate device, then download to all your Geomates.

With any software, you are bound to run into glitches and tech issues! This is where Google searching for solutions can be very helpful. Be patient, do some research, ask around, check the software requirements. A simple driver may need to be downloaded and your computer restarted first before it will work. Be willing to contact the software designers or check forums on their websites to dig for more info. if you're still having trouble.

There are others out there...this post only scraped the surface. Feel free to post any others in the comments!

Keep 'em educaching,
