LS.3.2.2: Use models to exemplify the distinct stages of the life cycle of seed…

Flowers, Fruit and Seeds: How Plants Make More Plants Grades 3–5 · partly supports this outcome

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.

• Is a tomato a fruit? 50–60 min

  Teams cut open thirteen foods to find where the seeds are, sort them with a scientist's rule instead of a cook's, and follow a flower into a fruit. They find that tomatoes, cucumbers and peppers are fruits, that a carrot is a root, and that a banana is a fruit with almost no seeds.
