A. REVIEW - Go over previous lesson about insects - name body parts. Introduce new type of bug to be studied - arachnids, specifically spiders. Today we will learn the different body parts of a spider.
B. OBJECTIVES -
I. Students will orally describe a spider as an arachnid that has eight legs and two body parts and will name the two body parts with 1 error.
II. Using a worksheet with a word bank, students will label the body parts of a spider with 1 error.
C. MOTIVATION - Read Anansi's Narrow Waist. Ask the students what the body of a spider looks like - how many legs and body parts.

Discuss the different body parts of a spider : legs, eyes, spinnerets, abdomen, and cephalothorax using the spider overhead and the spider posters. Discuss the body parts of spiders by examining small plastic spiders.
Ask questions about objectives to check comprehension.
E. PRACTICE - In cooperative groups, do WS #1 and WS #2, rewarding correct answers with sticks. Groups that finish early may color the spider page. Monitor and provide immediate feedback to the groups.
Homework - Do WS # 3 and WS # 4 and discuss tomorrow to reinforce lesson objectives.
F. CLOSURE - Ask students to state in their own words what they have learned while pointing out the objectives on the board. Relate this lesson to the previous lesson and tell the students about the next lesson that will be about different types of spiders.
