Students investigate how seeds form by examining real plants. They learn that seeds develop from flowers after pollination and fertilisation, compare seeds from different plants, and share their findings.
Bring several flowering plants and seed-containing fruits/vegetables.
Introduction
Ask: “If a flower grows from a seed… where did that seed come from?”
Discuss and lead to: “Seeds are made in flowers.”
The method Catch a Partner can be useful here.
Teacher Demonstration
Show several examples, e.g. tomato, sunflower head, pea pod.
Explain: After pollination and fertilisation, the ovary becomes a fruit and the ovules become seeds.
Group Investigation Materials
Divide the class in groups. Each group receives:
Flower Dissection
Students inspect the flower and sketch:
As questions as:
“Where do you think the seed would start forming?”
“Can you see pollen grains?”
Fruit Investigation
Students open the fruit to:
Observation
Students draw the flower and fruit, label parts, describe the seeds, and write a brief “From Flower to Seed” explanation.
You can use the method of Sketching for the drawings.
Class Reconstruction: The Journey of a Seed
Together, outline the seed journey:
Pollination → fertilisation → ovary becomes fruit → ovules become seeds.
Students who finish early can:
