Watch and Discuss: Building Dams II

Watch children build two dams. Then, see how they play a trick!


  • Building Dams II (video)

Key Science Concepts

  • You can stop the follow of water by building dams.


Before you watch: Tell children they will watch another video about children building dams—this time they build two.

After you watch: Ask,

  • The girls said that Jerry’s dam is “very solid.” What do you think they meant by that? What’s Jerry’s dam like?
  • The girls played a trick on Jerry—can you explain what it was?
  • How did the children solve the problem so that everyone had enough water?

Optional: Show the video a second time. Ask children what else they notice this time around.
