Lesson 7: Observing the Behavior of Frogs and Crabs Share observations made about the frog and the crab (Optional- Venn Diagram) Discuss “What we want to know …” (What have we learned and what questions remain?) 1

Extension: Life Cycle Wheel The Life Cycle of the Crab

Lesson 8: Living on Land: Millipedes Question: What will the millipede need in its habitat to survive? Hypothesis: Use the Animal Background sheet to predict what the millipede needs. Millipede Habitat Proposal Draw and describe your ideas for the millipede’s classroom home. 5

ANALYZE: What are the elements of the millipede’s habitat? Natural Habitat Classroom Habitat Water Moisture in soil, misting Space Tank Plants Moss Food Leaf litter, mushroom, lettuce, orange, apple Land Soil and gravel Light Indirect light through windows (dim light preferred) Air Small hole in tank Bark and leaves Bark, twigs, rocks, leaves TG 24

habitat and illustrate. Build the millipede habitat and illustrate.

Millipedes Keep soil moist by frequent misting Provide indirect or no light Provide daily food source—small handful of plant materials (lettuce, vegetables, fruit) or decaying wood or leaves Always handle with gloves

Feeding Observations What happened when you put food in the habitat? Do the millipedes respond to food the same way the frogs or crabs do? In what ways are the millipedes’ responses different?
