SUGGESTED ACTIVITIES:  (K3)

Use riddles (examples)
• It is a root.  It is red.  We cook it.  What is it?   (beet)
• It is a seed.  It is green.  It is almost round.  What is it?  (pea)
• It is a root.  It is orange.  Rabbits love to eat it.  What is it?  (carrot)

LEVELS (3-5)  Plants provide man with products other than food.

1. Direct the students in looking about the classroom to locate items derived from plants (paper, string, cork, rubber, and linen).  Ask students to bring in pictures of plants and materials derived from them for a bulletin board display.
2. Discuss that trees come from plants and their material gives us furniture, heat, paper, clothing, toys, shelter, nuts, fruits, and medicine.
3. Make a chart showing fruit.  We get our fruit from trees, shrubs, and vines.  The Fruit is the part of the plant containing the seeds.
4. Grow corn, lemon, avocado plants from seeds and display them in the classroom.
