Investigation: How Does Temperature Affect Respiration Rates
This lab is focused on fish and the metabolism of ectothermic (warm-blooded) animals. The investigation also be useful for beginning students in reinforcing good lab procedures and graphing. I’m always surprised by how many students have difficulty reading thermometers and setting up a water bath. This lab has been redesigned to make it simple and quick.…

The Blue Bottle Demonstration
Most biology teachers must eventually accept the awful truth that they will need to include chemistry in their biology classes. For years, the only chemistry I had to worry about was the very simple photosynthesis equation which was fairly easy to explain and also presented in an “unbalanced” form. When I started teaching AP…
