Reflection Questions

What strategies do you see Pat using to make the main points of this lesson clear for her young students?

Pat uses modeling and props to help make the content clear and the testing process understandable. 

  • Pat brings in a live day lily blossom to point out the parts of a flower instead of relying on the diagram on handout 3-7. (1:03)
  • Pat demonstrates the entire testing process before students receive any materials. (2:57)
  • After testing the marble, Pat models exactly how she would fill in the recording sheet that students are expected to use in their investigation. (3:29)

Where do you see Pat’s students being reminded about the features of controlled or fair testing?

Without ever mentioning the process of “controlling variables,” both Pat and her teaching aide take any opportunity they can to reinforce the importance of keeping everyone’s testing procedures the same.

  • Before beginning, Pat reminds students that “Everyone has to test the materials just the same way.” (1:53)
  • Pat’s teaching aide reminds her student to wrap the tape around her finger to test it, “just like Mrs. Slater did.” (5:24)
  • Pat explicitly talks about differences in procedure when discussing results of the aluminum foil tests, calling it “a different kind of experiment.” (7:40)
