Mitosis Coloring
Students read about each of the phases of the cell cycle and label and color a diagram that shows details of interphase, prophase, metaphase, anaphase, and telophase. Students must also label cell structures like the centrioles, aster, spindle, and nuclear membrane. This worksheet can be used as reinforcement for a lesson on mitosis and…

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: Osmosis and Water Potential
Students models osmosis using dialysis tubes that contain different concentrations of sucrose. The tubes will gain water dependent upon the molarity of solution they are placed in. You can make sucrose solutions with table sugar, and instructions are included in the teacher’s guide to the lab. The second part of the investigation determine the…

Case Study: How Do Bacteria Become Resistant?
Students analyze data regarding methicillin and penicillin resistant bacteria, focusing how hospitals inadvertently drive the evolution of resistant strains. Each section of the case explores an aspect of dealing with bacteria, including sanitation, analyzing agar plates uses the Kirby-Bauer disk method and concludes with students suggesting plans for reducing the incidence of MRSA in hospitals. With…
