"Outdoor & Environmental education
in a natural setting."
The natural environment is overflowing with opportunities for students to learn and have fun, but too often, the lessons that can be discovered from the outdoors are missed. Let us make your job easier by taking the students outdoors for experiences that reinforce concepts that you’ve taught in the classroom. Some of the lessons include:
CELP is designed to provide opportunities for young people to interact with the natural environment while deepening their understanding of science, math, and other academic areas.
There is also a teambuilding component to CELP that can help students learn to communicate and cooperate with one another. Teambuilding activities may include games and physical challenges that invite students to solve problems together.
By interacting and learning in natural settings through outdoor and environmental education students grow as individuals, and discover ways to show leadership in protecting the environment.
Calvin Center is located on 548 beautiful wooded acres in South Clayton County. Calvin Center is a year round camp and conference center owned and operated by the Presbytery of Greater Atlanta.
Our curriculum is your curriculum. The lessons that we offer are based on the curriculum standards for the State of Georgia. We offer and provide classes for those standards that could best be met using the rich natural environment. Programs may be modified to integrate any special topics your group would like covered. Our topics include...
The above is only a sample listing of our lessons. Discussion and close collaboration is provided to give teachers and educators what they are seeking as opportunities to achieve some curriculum standards that are difficult to accomplish at school or in the classroom.
Facilitators for groups come from varied backgrounds including; teachers, outdoor educators, graduate students, and mental health professionals. Each one of our facilitators is excited about working with children and youth and has different areas of expertise.
“Experiencing History...Today”
Allowing students experience events and opportunities is often the best way to learn. The Underground Railroad is a integral of American history. While we can never replicate or imitate what occurred over the course of those challenging years we can at least simulate in one small way some basic thoughts and feelings associated with those experiences.
Students will participate in the Underground Railroad as escapees running from sheriffs and bounty hunters. While participants are ‘on the run’ trying to make it to safety or jubilee they will be guided by ‘conductors’ whom will lead them from safe house to safe house finding out facts and stories from a time when freedom was given on the color or your skin.
Underground Railroad lesson is a cultural experience and a hands-on insight into the life of slaves and especially those led by Harriet Tubman and others to freedom. This is a great opportunity to take a history lesson outside! Through simulation, your group will be able to travel along the Underground Railroad and escape to freedom.

Please ensure all items are labeled and named. Calvin Center policy is to keep all lost and found items for one month. After which items will be passed on to a charity. Calvin Center will not be responsible for any items lost at camp.
Any prohibited items that are found will be held in the camp office until the end of the day or passed on to a teacher.
| Earth Day, Every Day | Our Earth is ticking away and for too long we thought we could do anything to it. Sadly we are learning from our past and current mistakes, and what better way to channel the future decisions than by educating the young? This lesson centers on giving students tools to affect change in their "environment" using the 3 R's (reduce, re-use and recycle). Students may measure the air quality at camp, make earth-friendly household cleaners or examine what we waste already by sorting through a bag of clean trash. Whatever activities are done, students will leave with easy steps to practice more “care of the earth” principles at home and school. |
| Rotten to the Core | The Rotten' world of fungi is much more than just mushrooms! Often overlooked, or even shunned, this kingdom includes wonderfully diverse and fascinating species. Students will learn how fungi differ from plants, discover the common characteristics of all fungi and then take a hike to discover the amazing amount and variety of fungi right under their noses. Along the hike the students will classify fungi into groups based on their methods of reproduction and see first hand the roles fungi play in the eco-system. Finally students will investigate the mysterious relationship between fungi and algae by studying lichens. |
| Lake Life | In aquatic environments, such as lakes and ponds, there reside a variety of plants and animals that are adapted to exist in such a watery environment. As with other habitats, lakes require a delicate balance of life. In this class, students will be introduced to the lake life at camp through initial exploration. Instruction and teaching points will be given as the group of students and adults explore this watery environment. Students will be encouraged to use all five senses to learn as much as they can during the class session. One goal of this session is to encourage and create a community of learners, knowing that each person (student or adult) can contribute to the whole group's learning. |
| Show Me the Way | The compass is a valuable instrument in the outdoors. In this class the students will not only learn how to use a compass, but will also gain knowledge of the physical and mathematical principals on which the compass is based. Students will learn how to take a bearing, follow a direction and pace to determine distance. After a few practice activities, students then put these skills to use on the center's compass orienteering courses. The course combines challenge, ingenuity and physical activity to require students to develop their compass skills to a fine "degree". |
| Always Take the Weather | We always talk about it… percentage chances of rain, severe storms, inches of snow etc. but where does it all come from? This lesson is about many peoples’ favorite topic - the weather. Students will investigate patterns of weather according to the time of year, what influence landforms play on it, and how we as humans are influencing the weather around us locally and globally. Students will use math to determine several examples of weather and its comfort level for us. |
| Low Ropes/ Initiatives | Teams can be the most fun while also the most frustrating thing. From an early age we are in teams of all types. There are certain things that make teams successful and even from an early age important team concepts of cooperation and listening can be taught to children and youth. Using the Low Ropes/Initiatives course these ideas can be reinforced while using fun and problem solving as a medium. |
| Climbing Wall | Ascend the heights of our wall. Scale the flat side or the harder side, which has over-hangs and slants to challenge all ages. Over forty feet in the up using a top roping system and trained facilitators see your students challenge themselves in a new way. |
| Campfire Magic | Come warm yourself by the fire, cook S'Mores, and hear the legend of Calvin's secret tree. Campfire is a fantastic time to reflect on the day, have some fun and learn at the same time. |
| Stars Are Out Tonight | Experience the Big Dipper; see Seven Sisters all at once and even gaze upon our neighbors in space. “Stars are out Tonight” offers students a firsthand look at the painted ceiling we call space and, depending on the weather, use maps to find the constellations that hang overhead. Students will also learn about why stars & planets move, and why some people see different stars in different parts of the world. This class is a fun way to learn almost hands on, what cannot be reproduced during the normal hours of school. You may even see a shooting star! |
| Clay Nation | Pinch that pot; roll that clay. Come and create your creation! Learn about how clay is made and why the clay we use is a different color from our Georgia red clay. What uses does clay have today compared to 100 years ago? Investigate the scientific properties of clay and use math to look at different temperatures used in the creation of all things clay. Work with our expert potter to experience the wonderful world of clay. While this program can be done in one session, it is best done over 2-3 days. |
| Bucky's Bungalow | In 1950 Buckminster Fuller wanted to build a home that would serve humans better and use less of the Earth's resources. He found that a triangle was the strongest shape known, and hence created Bucky's Bungalow. This activity allows students to work in teams and learn how to tie knots and understand the basics of what a geodesic dome is. The lesson incorporates considerable math as well as trigonometry. A great lesson for teamwork that enables students to see tangibly a finished product or goal. |
| Ahoy the Canoe | More than just floating on our 10-acre lake, this lesson incorporates all the skills in basic flat water canoeing. including basic and more advanced strokes. We also take this opportunity to introduce water-safety on lakes and flat waterways and to have fun playing water games. This lesson is great for building individual confidence, listening and decision-making skills. |
| The Beast | More than just a game The BEAST incorporates observing, listening and following directions while helping students understand how complex communication can be. Students are divided up into teams and using Tinker toys, follow a series of instructions to create an enlightening and fun learning experience. The BEAST is as enjoyable to watch as it is to participate. |
| Underground Railroad | A cultural experience that demonstrates a way life for slaves hundreds of years ago. A night only activity that allows students to try and make it from safe house to safe house without getting caught. A serious but also fun glimpse at what situations prevailed for those people like Harriet Tubman who took enormous risks to free slaves. A wonderful lesson in history that cannot be ignored, and one that ends with a celebration. |
| Let's Be Sensible | In a culture dominated by sights and sounds, students can become desensitized to the more subtle aspects of the natural world. Students will learn how to concentrate and become more perceptive by focusing on their senses. They will solve a mystery that involves using all their senses to discover natural wonders. Emphasis is on using our senses to discover as much about the natural world as we can and on the way animals acutely use their senses to help them survive in the environment. |
| Into the Woods | The Forest is alive with all sorts of interesting things. In this lesson students will determine the parts of a forest community. They will be introduced to or add to their knowledge of producers, consumers and decomposers, and how these three important aspects fit into a forest setting. This lesson will take place on Calvin's 548 acres and gives students a wonderful opportunity to explore, search, smell even taste the natural environment. They may even see some live animals. This lesson also focuses on creative writing and requires putting pen to paper and writing a "cake" mix for life in the forest. |
