Turtle Pond Exploration Materials Reading Connection: Jo McDonald Saw a Pond (Mary Quattelbaum) Engage Pond Exploration Tub Large pond nets Containers for holding water and pond specimens Book: Jo McDonald Saw a Pond SAFETY: Water is a drowning hazard and students must be closely supervised at all times. Any students with open cuts or scrapes on their hands should not be allowed to handle pond water or specimens. Have students sit around the picnic table. Tell students that they will be exploring the ecosystem of a pond. Ask: Do you know what an ecosystem is? Discuss. Guide students to the understanding that an ecosystem is a community of living and nonliving things that work together. Ask: What are some of the nonliving things of a pond ecosystem? (Answers should include water, air, sunlight, soil, rocks, etc.) Ask: What are some of the living things that you might find in a pond ecosystem? (Answers should include turtles, frogs, salamanders, fish, etc.) Explain Read Aloud: Jo McDonald Saw a Pond SAFETY continued: Banks of the pond can be slippery, WALK at all times. Dock can be slippery when wet, WALK at all times. ONLY 4 students allowed on the dock at a time. NO STUDENT ALLOWED ON THE DOCK UNLESS AN ADULT IS ON THE DOCK WITH THEM. At the conclusion of the story explain to students that they are now going to be exploring Turtle Pond. Tell students the safety guidelines of the pond exploration: 1. WALK at all times, the banks of the pond are slippery 2. Remain calm and quiet, you will see more! 3. No students are to be on the dock without an adult. 4. Only four allowed on the dock at one time 5. Use nets carefully so as not to injure the pond critters. 6. Do not touch any of the critters without permission and supervision. 7. Make sure your hands are wet when you handle salamanders 8. Any critters that are captured in your net must be put in water in the large viewing tubs immediately. 9. Any mud left in the nets should be put back into the pond, as there might be small critters hiding in the mud! 10. Keep your hands and fingers away from you face, especially your eyes, ears and mouth Check for thorough understanding of the safety guidelines. 1 Explore IMPORTANT! Do NOT handle any water insects, as they may sting or bite. Extend Do NOT use hand sanitizer. Hand sanitizer can be absorbed through the skin of the pond critters and may be toxic them. WASH HANDS WELL with SOAP and WATER at the end of the lesson. Evaluate Clean Up TAKE ALL STUDENTS TO THE ROUND HOUSE TO WASH THEIR HANDS!! Hand Sanitizer is not enough to clean hands adequately. Fill viewing tubs ½ full of pond water and put on the center of the picnic table. Provide each student with a net. Make sure you supervise students closely in the use of the nets. Allow students to collect critter from the pond. Remind them again not to run. Place the specimens in the containers with water so that students can easily see the pond critters. DO NOT handle any pond insects, as they may sting or bite. If students will be handling the salamanders, make sure the students have wetted their hands with water. Dry hands peel away the protective layer of mucus on the salamander, increasing its risk of infection. Handle critters gently, standing over the water tubs so that if they wiggle lose, the critters do not fall onto the ground. Ask: Students to identify the types of critters found. (Salamanders, turtles, frogs, etc.)They will not find any fish because the dissolved oxygen level in the water is too low to support fish life. Lead student to an understanding of the role of turtles, salamanders and frogs in the pond ecosystem. Discuss what each one eats. Salamanders eat daphnia, aquatic worms, mosquito larva and other aquatic insects. Turtles eat aquatic worms, insects, tad poles, small salamanders and snails and water plants Frogs eat insects and aquatic worms Ask: What is one thing that all the animals they looked at have in common? Answer: They all need WATER to live in. Return all critters to the pond in a gentle manner. Make sure that all nets are free of mud and plants Stand nets on end with net part up leaning against a tree to dry. Make sure all viewing containers are empty. Have students wash hands well in the round house. 2
