Question: What characteristics of the millipede help it to survive in its natural habitat?

Hypothesis: (Predict & share)

Plan: Observe the features of the millipede using a hand lens (in a tank and in a cup)

*Complete/Incomplete Metamorphosis:

Metamorphosis is called complete when there is no suggestion of the adult form in the larval stage, e.g., in the transformation from tadpole to frog or from larva to pupa to adult in bees and butterflies.

When the successive larval stages resemble the adult (as in the grasshopper and the lobster), metamorphosis is called incomplete.

Millipedes Found in North American woodlands as well as

deserts Long segmented trunk Round head with antennae pair for feeling,

smell, and taste Two pairs of legs attached to most segments Vary in color—black, brown, some are vividly

colored Avoid light—some are blind Play dead when distrubed Defense mechanism—stink glands May live for several years

Respond to part B based on the research question below:

How often does the crab go into thewater?

Reading Selection: What Makes Beavers Special?Read the selection and answer the following questions.

1.What special characteristics do beavers have that help them survive in their habitats?

2.In what ways to beavers change their surroundings so that they can survive?

3.What other animals can change their surroundings so that they can survive?
