Flowers, Fruit and Seeds: How Plants Make More Plants Grades 3–5

What is a flower really for? Is a tomato a fruit? How can a seed travel without legs? Three hands-on lessons on pollination, fruits and seeds, and seed dispersal, from a flower you can take apart, through foods you can cut open, to seed models you can drop, blow and float. Nothing is tasted, and it works in any climate.

• What is a flower really for? 50–60 min

  Teams take a real flower apart, find the petals, the pollen-making stamens and the seed-making pistil, and use a cotton bud as a model bee to test why fuzzy carriers move pollen well. They explain what pollination is, what it is not, and why a flower looks the way it does.

• How can a seed travel without legs? 60–75 min

  Teams build a model seed for wind, water or animals, carrying the same clay seed, and test every model with a fair drop, fan, float and wool test. They find that no design wins every test, and explain how real seeds are shaped for the way they travel.
