Estimate a Person’s Height from the Bones
In this activity, students use tape measures to estimate the length of their femur, ulna, and tibia. These lengths are then with an equation to estimate their height which can then be prepared to their actual height.

The Tardigrade Project
This project was created for AP Biology students where they scrape lichens from trees near campus and filter them over night so that tardigrades and other microorganisms can be collected from the water.

Cells Alive Worksheet
This worksheet follows diagrams and activities at CellsAlive.com which focuses on the size of cells compared to other objects, such as viruses and pollen. Students view interactive plant, animal, and bacteria cells to learn about the different structures associated with each.

What Causes Mitochondrial Disease – CER
Describes genes in the nuclear DNA and in the mitochondrial DNA and proteins found in the inner membrane of the mitochondria. Mutations can lead to disorders.

Investigation: The Effect of Salt on a Potato
Students observe how the mass of a potato slice changes when soaked overnight in salt water. The activity is intended to be done as part of a lesson on osmosis and hypertonic and hypotonic solutions. Students will need about 15 minutes to set up their cups, weigh their slices and make predictions about what they…

Mitochondria, DNA, and the Aging Process
This short article was designed for anatomy and physiology students studying the cell. The class focuses on how disease states can often be traced back to problems with cells. Senescence, or aging, has been linked to a build-up of mutations in mtDNA.

Investigation: How Does a Water Strider Stay Afloat?
This lab was modified from the “Penny Lab” to focus more on the properties of water and how surface tension is important for aquatic organisms like the water strider. The instructions were designed for an intro (vocational) biology class that only meets for a semester.

Microscope Introduction – “e” Lab
This lab is similar to the “e” lab used with freshman biology, but designed for students in the vocational track. It has less reading and more detailed steps for using the microscope as well as a larger font and bigger spacing.

Teddy Graham Lab Modeling HW Equilibrium
Model Hardy Weinberg equilibrium using Teddy Grahams. Compare happy bears to sad bears.

Investigation: Exploring Cells
While biologists might find the history of the cell theory fascinating, I notice that many of my students seem to tune-out when you bring up the history of scientific discoveries. In order to save time and improve engagement, I created this lab to include a short history of the cell theory as students explore prepared…

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.

Video Lessons Graphic Organizer
This lesson introduces students to the idea of watching videos at home, taking notes, and then coming to class with understanding and knowledge to apply to a classroom activity, like a lab or discussion. Students watch a 4.5 minute TED Ed video and complete a chart on the main ideas and details.

Investigation: How Can Diffusion Be Observed?
This investigation provides a hands-on way to observe what happens when a chemical moves across a semipermeable membrane. In this case, a cheap plastic bag serves as a model for the cell membrane and shows that iodine will move into the bag and turn the contents purple.

Create a Concept Map of Biomolecules
This activity asks students to work in groups to create a concept map (graphic organizer) on the biological macromolecules: carbohydrates, lipids, fats, and nucleic acids. Students are given brief instructions and a sample map to get them started, but they are responsible for determining what details are important in each section.
