In trying to decide what to cover for seventh grade Physics, I perused the Main Lesson Book (MLB) of a friend of mine, who used to be a Waldorf teacher. I also looked over Eugene Schwartz's site to see what he prescribes for the block. So much to cover...what to choose? I chose Sound, Light, and Heat.
I decided to start with Sound, using books from the library to find appropriate experiments. My goals were to cove : What is Sound? What is Silence? How does Sound Effect Us? What Actions Cause Sound? What Effects the Quality of Sound? How Does Sound Travel?
I also took the opportunity to teach the Boy how to write out the process of the experiment using Question (Hypothesis), Procedure, Observation, and Conclusion. A format that was used when I was a kid. It may be obsolete due to new teaching methods, but my point was to get him to follow a process and be able to get that on paper.
Below are some photos of the Boy's MLB and some photos of our sound experiments.
