Investigation: Habitat Selection in Flour Beetles
This activity was modified from an Advanced Placement Investigation for use with freshman classes. The instructions are clear and require students to examine data and create a graph. Then students collect their own data using Choice Chambers and can choose which variables they would like to test: wet vs dry, water vs vinegar, light…

Photosynthesis Lab – How Light Color Affects Growth
A virtual simulator that shows how plant growth changes in response to the color of light. Students measure the heights of plants grown under different colors.

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…

Investigation: What Factors Affect the Heart Rate of Daphnia
This investigation starts with a guided procedure where students gather data on the heart rate of daphnia when the organism is exposed to 1% ethanol. Daphnia are tiny crustaceans that are visible with the naked eye, though a microscope or stereoscope will be needed to see their heart rate.

Investigation: Temperature and Fish Respiration Rate
Students investigate what happens to the respiration rate of a fish as the temperature is decreased. Analyze data and create a graph.

Investigation: Plop Plop Fizz Fizz
This investigation asks beginning students to develop a hypothesis about how quickly an effervescent tablet will dissolve and then design an experiment.

Case Study – Investigation of Animal Behavior
The goal is for students to develop a basic understanding about how animal models are used to study behavior and how behavior can be explained from an evolutionary perspective.
