  • Enzymes and Substrates – Coloring

    Enzymes and Substrates – Coloring

    A simple worksheet showing how enzymes bind to substrates to create products. Students color a graphic and answer questions.

  • Catalase Activity in Yeast Using Sodium Alginate

    Catalase Activity in Yeast Using Sodium Alginate

    Create yeast spheres using sodium alginate to test the rate of enzyme reactions at different concentrations and temperatures.

  • Investigation: Model Enzyme Activity with Toothpicks

    Investigation: Model Enzyme Activity with Toothpicks

    Use toothpicks to model enzymes. Explore substrate and enzyme concentrations by changing toothpick numbers. Model competitive inhibition by taping fingers.

  • Explore the Senses

    Explore the Senses

    Students rotate between 6 stations where they perform tasks to perform related to the senses, such as two point discrimination and reaction time.

  • StoryLab: How Enzymes Work

    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: How Do Enzymes Work?

    Investigation: How Do Enzymes Work?

    This lab is fairly basic, but when given with guided instruction how enzymes catalyze reactions, students can have a hands-on experience into how proteins are related to function.

  • Photosystems and Chemiosmosis Coloring

    Photosystems and Chemiosmosis Coloring

    Use this coloring worksheet to explore how plant cells harvest energy form the sun to generate ATP in the process known as chemiosmosis.   

  • How Does Photosynthesis Work?

    How Does Photosynthesis Work?

     This worksheet requires students to label the major events that happen in photosynthesis and write the equation.   Students also label a chloroplast showing the light-dependent reaction with its reactants (water) and products (oxygen, ATP, NADPH.)     The light-independent reaction is also shown to illustrate how ATP and NADPH are energy-carrying molecules that power…

  • The Blue Bottle Demonstration

    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…
