Investigation: How Do Enzymes Affect Gelatin
This lab explores enzymes using fresh and canned pineapple to observe enzyme-substrate reactions.
-
Cell Membrane Transport Graphic Organizer
Label a graphic that compares the types of transport in a cell, such as osmosis, diffusion, and active transport.
-
How Do Legionella Bacteria Cause Disease?
Analyze a graphic that shows how legionella bacteria are taken up by cells through phagocytosis and reproduce in the phagosome.

Investigation: Water Potential and Carrot Molarity
Determine the molarity of baby carrots by soaking them overnight in different solutions. The point at which the carrot does not change mass is the molarity.
-
Investigation: Viewing Stomata in Zebrina Plants
View the stomata of plants with this simple activity that uses tape and fingernail polish. Great for beginning biology students!

Boxing Biomolecules – A Game for Organics
AP Biology students learn the four biological macromolecules by playing a game with boxes which have descriptions on each side.
-
Investigation: Algae Beads and Photosynthesis
Students use algae beads to observe photosynthesis and respiration. Algae beads are placed in an indicator solutions to measure CO2.
-
Investigation: Meiosis in Sordaria Fungus
Students determine cross-over frequency in sordaria by examining an image. showing how meiosis results in unique combinations.
-
Investigation: Determine Molarity of Unknown Solution
Students determine the mass of water beads after soaking them in solutions. They use the change in mass to determine the molarity.

Modeling Meiosis and Independent Assorting Using Slides
Meiosis is a difficult topic for beginning biology students. There’s a lot going on in the cell to ensure that each new gamete receives half the DNA of the parent cell. In addition, each new cell is completely unique. This is the result of independent assortment and crossing over. Lessons on meiosis generally involve labeling…

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.…

Investigation: Mitosis
This mitosis investigation was created during the 2020 pandemic for remote learning. In previous years, biology students would view slides in the lab and analyze data on cancer and mitotic index. This at-home activity only looks at the mitosis of onion cells and I plan to add cancer and mitotic index as a separate activity.…
