Fruit Dissection
Explore how flowering plants (angiosperms) reproduced in the Cretaceous and how seeds help plants survive and spread.

Materials Needed:

• A variety of fruits (examples: apples, oranges, tomatoes, bell peppers)
• Plastic knives or kid-safe cutting tools
• Paper plates or trays
• Paper and pencil for recording observations
• Optional: magnifying glass

Instructions for Parents:

1. Set the scene: Explain to your child that during the Cretaceous Period, flowering plants appeared for the first time. Insects and other animals helped these plants reproduce by moving pollen from flower to flower.
2. Pick a fruit: Choose a fruit with visible seeds. Remind your child that every seed started as a flower during the Cretaceous.
3. Dissect carefully: Help your child cut the fruit open. Look at how seeds are arranged inside. Compare with other fruits.
4. Count the seeds: Have your child count the seeds in each fruit and write it down. Discuss how plants might use these seeds to grow new plants.
5. Observe differences: Ask questions like:
   • Are some seeds bigger or smaller than others?
   • How are the seeds packed inside the fruit?
   • How might seed size or placement help the plant survive and spread, just like Cretaceous plants had to adapt to their environment?
6. Optional extension: Compare seeds from a fruit that grows on a tree vs. one that grows on a vine. Discuss how plant diversity during the Cretaceous allowed insects, herbivores, and even dinosaurs to interact with plants in many ways.

Parent Talking Points / Connections to the Lesson:

• Level 1: “In the Cretaceous, flowers appeared and made seeds. Seeds help plants grow new plants.”
• Level 2: “Flowering plants changed Earth forever by making seeds and using pollinators. Look at how seeds are packed inside fruits — each one is designed to survive, spread, and continue the plant’s life cycle, just like during the Cretaceous.”
