Modeling Survivorship Curves with Bubbles
A fun activity to model survivorship curves using bubbles. Students blow bubbles and time how long each survive under different conditions, then create a graph.

Photosynthesis Virtual Lab
This lab was created to replace the popular waterweed simulator which no longer functions because it is flash-based. In this virtual photosynthesis lab, students can manipulate the light intensity, light color, and distance from the light source. A plant is shown in a beaker and test tube which bubbles to indicate the rate of photosynthesis.…

StoryLab: How Enzymes Work
This story lab aligns to an investigations students do with enzymes where they put hydrogen peroxide on liver and observe bubbles produced from the reaction with catalase. This investigation has several versions for different levels of biology (regular track, intro, and AP) though the story lab was intended for the intro track students who do…

Investigation: Enzymes Activity with Catalase
Have you ever noticed that when you pour hydrogen peroxide on a wound, it bubbles? The reason is that bacteria and your own tissue contains an enzyme that breaks down the peroxide. Peroxide splits into a molecule of water and a molecule of oxygen, which causes the bubbles. In a series of tests, students observe…
