Extra Activity: Woolly Sock Walk

Burrs are seeds that travel by hitching a ride on an animal's fur or a person's socks. If you have a weedy area near your school, your students can discover what hitchhiking seeds live in your area by going on a woolly sock walk.

On a dry day in autumn, have each student bring in a woolly sock big enough to wear over their shoe. After going for a walk through the weeds, have students pull off the seeds that they have collected on their socks and figure out how the seeds stuck to the socks. Student can even plant the seeds and see what plants grow. (Read more ideas for this activity.)

These videos from the BBC Private Life of Plants show how different kinds of seeds travel in different ways from their parent plant.

• Seeds in flight (2:26)
• Ants help move seeds (0:56)
• Fruits attract birds so the seeds inside can travel (1:25)
• Some plants even move their seeds up tall walls (1:04)
