From the time the pussy willows open in early spring until the last of the asters, spring, summer, and fall are the seasons of flowers. They are glorious – but why do they exist at all? Like the singing of birds and the taste of ripe strawberries, they give us great pleasure, and for some that’s enough – but flowers are essential to the lives of flowering plants. Blooming is the culmination of months or years of growth, and understanding their parts will illuminate what they do.
Flowers have four kinds of parts and they are in predictable positions. If we look into a flower as a pollinator might, we see small but important parts first. In the center is the female pistil, which forms the seeds and catches the pollen. The pistil has an ovary at its base, which contains one to many ovules, the tiny eggs that develop into seeds when fertilized. The pistil is topped by its stigma, which is sticky or feathery and situated so that it will collect pollen. Between the stigma and the ovary is a stem, or style.

FOCUS: Flowers come in all shapes and sizes, but they all serve the same function: to produce seeds. We’ll look at the insides of flowers to see how seeds develop and compare different kinds of flowers and their structures. To make seeds, flowers need to be pollinated. Some do this with the help of the wind and others with the help of animals, like hummingbirds, moths, beetles, and especially bees.
Introduction: Hold up a plant with flowers, or a bunch of flowers. Ask the class, “What are some things you notice about flowers? Do you know why a plant has flowers?”

FLOWERS TO FRUIT ALIGNMENT WITH
NEXT GENERATION SCIENCE STANDARDS
The activities in this unit help children understand the basic concepts in the Disciplinary Core Ideas listed here. You can use the following list as a guide for lesson planning. These Disciplinary Core Ideas are taken from Grade Band Endpoints in A Framework for K-12 Science Education. Additionally, our activities give children opportunities to engage in many of the Science and Engineering Practices and reflect on the Crosscutting Concepts as identified in the Next Generation Science Standards.
