    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

    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

    Investigation: Enzymes

    This simple investigation can be completed using materials easily obtained from stores.  In a series of tests, students observe how the enzyme catalase breaks down hydrogen peroxide into oxygen and water.  Catalase is found in  living tissues, but a good reaction can be observed when using chicken livers.  The bubbling of the peroxide serves as…
