Key Science Concepts
- You can stop the follow of water by building dams.
Directions
Before you watch: Tell children that they’ll watch a video in which children make a dam.
After you watch: Ask:
- Did the way the girls built their dams remind you of what you did yesterday? What did you do that was similar? What did you do that was different?
- What problems did the girls run into when they built their dams? How did they solve their problem?
- What did they use to block the crack in the bricks? Did it work?
Optional: Show the video a second time. Ask children what else they notice this time around.
