Activity 2: Seeds (Adapted from OBIS
Seed Dispersal Lesson)
Materials:
- Seed-go Card for each team (mounted on cardboard and
laminated if possible)
- Old sock for each team
- Tape or glue
Gear Up:
- Ask students what they know about plant seeds.
- Ask them what seeds do and how.
- Ask for their ideas about how seeds get from the mother
plant to where they can grow. What are some of the strategies they use?
Explore:
- Pass out the Seed-Go cards.
- Tell students that this is a game similar to Bingo.
- Teams are to search for seeds that are dispersed in a
variety of ways.
- The seeds are then taped or glued in the appropriate
spaces on the Seed-GO Card.
- Allow students to go for a set amount of time and then
recall them.

Generalize:
- Ask teams to share their findings (cards) and strategies
they used to find different types of seeds.
- Ask students for their ideas about why the seeds have
different dispersal methods
- Ask which type of dispersal was the most common on the
cards.
- Ask for their ideas about why this might be.
Explore
- Give each team or student an old sock. Have them put
the sock over a shoe and walk where they think there might be a lot of seeds.
Record where they walked on a chart for later reference.
- Put the socks in plastic bowls and keep them damp but
not underwater.
- Have students observe and record.
Generalize
- Ask students for their observations. How are the socks
alike? How are they different?
- Ask students what their ideas are about why some socks
sprouted more than others.
- Ask students for their ideas about how the seeds got
to the place where they were picked up with the sock.
Assess
- Find and describe (in words and/or pictures) evidence
of a living organism using a non-living natural object. Describe the organism,
the non-living object, and how it is being used.
- Journal entry - describe as many ways as you can that
seeds disperse themselves
