Enzymes Help Us Digest Food

In the hands-on activity, Enzymes Help Us Digest Food, experiments with the enzyme lactase and discussion questions help students to learn about enzyme function, enzyme specificity, and the molecular basis for lactose intolerance. Students also learn about the scientific method by interpreting evidence to test hypotheses and designing the second and third experiments to answer specific scientific questions about lactase. An alternative version of the Student Handout which gives specific instructions for all three of the experiments is provided as an attachment below.

Cellular Respiration and Photosynthesis -- Important Concepts, Common Misconceptions, and Learning Activities

 This overview of energy, cellular respiration and photosynthesis summarizes important concepts and common misconceptions.  It also suggests a sequence of learning activities to overcome misconceptions, develop student understanding of important concepts, and relate these concepts to familiar topics such as breathing, food, body weight, and plant growth.

The attached file has the key concepts and suggested learning activities.


Where Does a Plant's Mass Come From?

The questions in this worksheet/discussion activity help students understand that a large part of a plant’s mass consists of water, most of the biomass comes from carbon dioxide, and minerals from the soil contribute only a tiny amount of the plant’s mass. The first attached file has the Student Handout and the second attached file has the Teacher Notes.

Plant Growth Puzzle

This worksheet/discussion activity presents a structured sequence of questions to challenge students to explain why plants that grow in the light weigh more than the seeds they came from, whereas plants that grow in the dark weigh less than the seeds they came from. The first attached file has the Student Handout and the second attached file has the Teacher Notes.

Photosynthesis & Cellular Respiration

Students use puzzle pieces representing the components of the equations for photosynthesis and aerobic cellular respiration and answer questions about these processes. The attached file has the Student Handout.

Barley and Oat's Brewing Backfire

In this worksheet/discussion activity, students compare aerobic cellular respiration and alcoholic fermentation and then interpret evidence to figure out why a micro-brewer’s beer has no alcohol.  The first attached file has the Student Handout and the second attached file has the Teacher Notes.
