Labs & Activities

Hands-on labs and class activities for Biology and Foundations of Biology. Each page has a student procedure, a data table that draws your graph, analysis questions, and teacher notes. The labs follow the Biology sequence, and Foundations of Biology uses the same labs where its standards match.

Enzyme labs Biology Unit 2 (BIO.1B)

Choose the lab that fits your materials. All three test how conditions affect an enzyme. Short on time? Use the Quick Catalase Lab (virtual), or explore Enzyme Diversity from the simulations page.

Biology BIO.1B.2 · Foundations FB.2.6

Catalase in Liver or Potato

Foam height with changes in temperature and pH. The most common enzyme lab, with a no-mess potato version.

What Stops an Apple from Browning?

Test treatments on cut apple and score browning over time. Very low cost.

Biology BIO.1B.2 · Foundations FB.2.6

Why Fresh Pineapple Ruins Gelatin

A protein-digesting enzyme and the effect of heat. No smell.

Cells Biology Units 3–5 (BIO.1C–1E)

Biology BIO.1C.1 · Foundations FB.3.2

Organelle Speed Dating

Students write and read dating profiles as organelles while the class matches each profile. Paper only.

Biology BIO.1D.1, BIO.1D.2 · Foundations FB.3.3

Membrane Lab: What Passes Through?

Dialysis tubing as a model membrane: test selective permeability with starch and iodine, then measure osmosis with sucrose solutions.

Biology BIO.1E.1 · Foundations FB.3.1

Same DNA, Different Cells

Six cell cards show how cells specialize from the same DNA. Paper only.

Evolution Biology Unit 10 (BIO.4)

Biology BIO.4.4, BIO.4.5 · Foundations FB.5.4

Predators and Camouflage

Model natural selection with paper prey over several generations, then change the environment.
