How Do Viruses Infect Cells (Coloring)?
A simple worksheet that explains how viruses infect cells which include diagrams to label and an image of a typical virus for students to color the envelope, proteins, DNA, and the capsid.
-
Reinforcement: Cell Division
This worksheet was created for an introductory biology class because they struggled with the difficult vocabulary associated with mitosis and the cell cycle.
-
Cell Membrane Captions
Students examine images of transport across the cell membrane and identify key features such as the phospholipid bilayer, channel proteins, and receptors. Students then provide a title, such as “osmosis” and create a caption that describes the process being shown.
-
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.

Zoo Scavenger Hunt
A scavenger hunt for the zoo. Students to find animals from the list and photograph them with their cell phones and upload them to Google classroom.
