  • CER – How Effective Are Masks at Preventing Disease

    CER – How Effective Are Masks at Preventing Disease

    Students examine data that show the effectiveness of mask wearing and the prevention of disease. The activity is a CER format (claim, evidence, reasoning.)

  • DNA Lesson Using PTC as an Anchoring Phenomenon

    DNA Lesson Using PTC as an Anchoring Phenomenon

    Describes how using anchoring phenomenon can improve lessons on teaching DNA and how the sequence of DNA determines structure and function.

  • Error Bars, Carl Sagan, and the Demon Haunted World

    Error Bars, Carl Sagan, and the Demon Haunted World

    Read an excerpt from Carl Sagan to discuss uncertainty in science. Students learn how to use error bars to determine validity.

  • Construct a Chordate Cladogram – Guided Learning

    Construct a Chordate Cladogram – Guided Learning

    Students learn how to construct a cladogram with this guided learning activity that focuses on the chordate group.

  • Modeling Meiosis and Independent Assorting Using Slides

    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…

  • CER and Data Analysis

    CER and Data Analysis

    CER introduction to scientific argumentation (claim, evidence, reasoning), Analyze a graph showing ACE2 receptors by age group.

  • Medical Errors – Don’t Use Pure Water Intravenously

    Medical Errors – Don’t Use Pure Water Intravenously

    I created this mini case study from a story about a patient given sterile water instead of saline in an intravenous drip solution. Students should probably have a learned about tonicity (hypertonic, hypotonic, and isotonic) before attempting this activity. The worksheet describes a scenario where a patient was hyperglycemic and the doctor ordered water be…

  • Podcast – Good Vibrations and Treehoppers

    Podcast – Good Vibrations and Treehoppers

    Introduce your students to the world of science podcasts! Listen to a short audio clip on treehoppers and how they use sound to attract mates.

  • Evolution and the Peppered Moth Game

    Evolution and the Peppered Moth Game

    Based on experiments showing moths evolve in response to pollution. Play a game where you try to catch moths in different environments

  • Label Digestive System

    Label Digestive System

    This worksheet was designed for anatomy students to practice labeling the organs of the digestive system. It is a little more advanced than what is typically seen in health or basic biology classes because it includes the three sections of the small intestine (duodenum, jejunum, ileum) and the three sections of the colon. (Note: I…

  • Jim Allison: Breakthrough

    Jim Allison: Breakthrough

    The film, “Jim Allison: Breakthrough” can be streamed through online platforms, like PBS or from Amazon Prime Video. Teachers can sign up for a free license at  https://www.breakthroughdoc.com/for-educators The film is 1 1/2 hours long, which is longer than most class periods, and many teen attention spans, so I split the worksheet into two halves.…

  • Can Plants Learn?

    Can Plants Learn?

    An experiment to determine if plants could learn by association Identify key features, such as variables, controls. Based on a real experiment in Nature.com.

  • Population Genetics in a Fishbowl

    Population Genetics in a Fishbowl

    Students learn about Hardy-Weinberg equilibrium by exploring a virtual population of koi fish. This virtual lab allows students to run experiments where they can change variables, like population size, migration rate, mutation rate, and fitness of two separate alleles. The alleles being studied control the coloration of the fish. Fish can either be white, gold,…

  • Understanding the Evolution of Limbs in Snakes

    Understanding the Evolution of Limbs in Snakes

    Where did snakes come from? There’s a popular story about snakes in Ireland and how they were lead away by St. Patrick. From a science perspective, snakes likely never were in Ireland to begin with. Many islands don’t have snakes. Why? Because they haven’t had time to evolve there. The activity is adapted from Understanding…

  • How Can Changes in a Population Lead to New Species?

    How Can Changes in a Population Lead to New Species?

    This lesson explores the two models of speciation: allopatric and sympatric. You can also assign a simple print version that explores speciation modes. Students first read about allopatric speciation and apply it to the finches on the Galapagos islands. Each finch species became isolated on its own island, which resulted in each island having a…
