I have never been invited to burn peanuts with a bunsen burner. Showing the relationship between chemical energy and thermal energy and the sometimes surprising differences between foods?

I think we had too much separation between diet classes and physical science. I think I recall doing something like a puzzle, with physical pieces, where you tried to make a days food using different foods. The point was that it’s easier and you get more if you pick the healthier foods. Instead everyone knew what the point was and then fucked around making the dumbest possible meal that fit the defined criteria.
I seem to recall the teacher not being amused with my solution that only has one food group per meal. (What’s for breakfast? 9 eggs. Lunch? 3 unseasoned grilled chicken breasts. Dinner? Six baked potatos, plain)
