Activity 1
Sort the pictures of arthropods any way
you choose.
 You must be able to state a reason for the
categories.

Activity 2

Sort your piles of pictures again by
separating the insects from the noninsects.
Activity 3

Sort your group of arthropods into insects,
arachnids, myriapods, and crustaceans.
