Dandelions – Background

Even the smallest child recognizes the common yellow dandelion. Their sunny flowers, bundled and offered as bouquets, are one of the first signs of spring. Whether they bring a smile or a frown, one can’t help but admire a plant that seems to be able to grow anywhere – from lawn to roadside, from parking lot to playground. Dandelion flowers serve the same function as all other flowers: to produce seeds for the next generation. While not native to North America, dandelions are here to stay, thanks to a whole host of strategies that ensure their fluffy seeds will be floating on breezes far and wide.

The dandelion, or Taraxacum officinale, gets its common name from the French “dents de lion” or teeth of the lion, thought to describe its jagged leaves.

Dandelions – Activities

FOCUS: Dandelion flowers serve the same function as all other flowers: to produce seeds for the next generation. Whether you consider them wildflowers or weeds, these hardy plants are here to stay and they provide an important food source for birds, bees, and other animals. We’ll dissect simple flowers to see how seeds develop and compare these to the complex structure of dandelions. Heading outside, it’s easy to find examples of dandelions in all stages of development and get a first-hand view of the progression from flower bud to fluffy white seed head. You and the wind can help spread their parachute seeds far and wide.

Introduction: Hold up a dandelion plant with flowers, or a bunch of dandelion flowers. Ask the class, “What are some things you notice about dandelions? Do you know why a dandelion has flowers?” Continue reading Dandelions – Activities

Dandelions – 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.
