QUESTION 1
How many body parts and legs does an insect have?
Three body parts (head, thorax, abdomen) and six legs.
QUESTION 2
Why is a spider not an insect?
A spider has eight legs and two body parts, not six legs and three parts, so it is an arachnid, not an insect.
QUESTION 3
Name one helpful job insects do.
For example, bees pollinate flowers, worms enrich soil, or insects feed birds and other animals.

Create: my insect.

Have students draw an insect with three body parts, six legs, and antennae, then label each part, so the insect checklist sticks. A printable insects worksheet is in the Science library.
