Activity #1 Now that you have learned about the fruit, when I say FRUIT you are going to get up and walk around the room with a clip board, paper and a writing utensil and examine the various fruits that are on each desk. You are going to categorize the fruit, and discuss with your group (people from your table) about the parts of the fruit (ovary, pistil, mesocarp, ect.) You will turn in this paper at the end of the hour. EVERYONE must do it! Fruit dissection will begin tomorrow (FRIDAY)
