  • Genetics Practice Problems – Easy Mode

    Genetics Practice Problems – Easy Mode

    This worksheet was created for an introductory level biology class. This worksheet is designed to move through difficulty levels, so students start with “easy mode,” then moving to “normal” and then finally “hard mode.” Students can move at their own pace, which instructors can help students who are struggling.

  • Cellular Respiration Graphic Organizer

    Cellular Respiration Graphic Organizer

    Students complete a graphic organizer that shows the process of cellular respiration. 

  • Karyotype of Tasmanian Devil Chromosomes

    Karyotype of Tasmanian Devil Chromosomes

    Students cut out each chromosome and organize them in pairs based on their patterns and size, they number them to determine the diploid number for the species and then consider a situation where the animal has an extra chromosome.  Students must determine which set has the extra chromosome and consider the concept of trisomy.  

  • How Do Viruses Infect Cells (Coloring)?

    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

    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

    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

    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

    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

    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

    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

    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

    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?

    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 – Basic “e” Lab

    Microscope Introduction – Basic “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

    Teddy Graham Lab Modeling HW Equilibrium

    Model Hardy Weinberg equilibrium using Teddy Grahams. Compare happy bears to sad bears.
