BFSU A-3: Air is a Substance and the Concept of the Atmosphere

I neglected to take any pictures today. Oops.

Yesterday we had something come up that interrupted our planned science day, but we did have time to watch some videos, so we watched the BrainPop video on Atmosphere and took the quiz. My kids really enjoy doing the quizzes (so much so that they fight over who gets to answer the questions..sigh) and I like the chance to review the concepts taught. Today we did the lesson from the book. One thing we didn't do was make a ruler balance and test the empty balloon vs. inflated balloon weight. I got out our digital gram scale and thought that would be sensitive enough. It wasn't. We did do the experiment where you crumple paper in the bottom of a cup and then submerse it (straight down, with the opening facing down) and the paper stays dry because of the air pocket that forms.

We finished up by watching the Bill Nye episode about Atmosphere. It was kind of a simpler lesson than some of the others, as we have done experiments with air before in our co-op.
