1. 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

5. 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

6. ANALYZE: What are the elements of the millipede’s habitat?
Natural Habitat
Classroom Habitat

9. 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

10. 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?
