  • Boxing Biomolecules – A Game for Organics

    Boxing Biomolecules – A Game for Organics

    AP Biology students usually start the year learning about biological macromolecules. I often get students wondering why they are learning chemistry in biology class. I assure them that living things are really just bags of chemicals! If you want to understand how they work, you need to understand the chemicals. We start by going through […]

  • Investigation:  Meiosis in Sordaria Fungus

    Investigation: Meiosis in Sordaria Fungus

    I find that my students really have difficulty with meiosis. I’m not as concerned with them memorizing the phases (though that is part of the lesson) as I am with them understanding how the process contributes to variability. I have several worksheets the model the process, like the “meiosis label” slides where students view images, […]

  • Biomolecules – Guided Learning

    Biomolecules – Guided Learning

    This lesson was inspired by a POGIL lesson on proteins, though I have made this one for remote learning and shortened it. Like other process oriented guided learning activities, this one gives students graphics and information and then has them perform tasks to build their knowledge and understanding of the topic. The slides start with […]

  • The Calvin Cycle

    The Calvin Cycle

    I created this activity for my AP Biology students on a day that I had to be out of the classroom. The activity uses a TED-ED video on the Calvin Cycle that explains how the cycle works to create glucose and to regenerate RuBP. The TED video goes into specific details about how RuBP used in the process […]

  • Pedigree Analysis – AP Bio

    Pedigree Analysis – AP Bio

    This worksheet was designed for AP Biology students studying genetics. Students are not given the inheritance pattern for diseases like Marfan Syndrome and Charcot-Marie-Tooth disease. Students must determine whether the disorder is dominant, recessive, or sex-linked from the diagram. Questions ask students to provide reasoning for their choices and they must indicate the genotypes of […]

  • Falling Cats – CER

    Falling Cats – CER

    Students practice Claim, Evidence, and Reasoning (CER) while examining the relationship between falling height and cat injuries. The graphs show that cats who fall 2-7 stories often suffer more injuries than cats who fall from greater distances. Not much information is given about how the data was collected, though the original source is included, I […]

  • DataClassroom


    High school biology classrooms often lack the time and resources to do long term studies and data collection that researchers engage in. Luckily for us, many projects make their data available for use by schools. Organizations like HHMI and Data Nuggets have created student resources that focus on analyzing real scientific data. One of these […]

  • 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.

  • Create a Concept Map of Biomolecules

    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.

  • Case Study:  How to Survive a Cholera Epidemic

    Case Study: How to Survive a Cholera Epidemic

    In this case, students explore how cholera is spread and how it affects the body.  The case is divided into four sections, with the first part focusing on the role of clean water supplies and the spread of bacteria.   In the second part, the affects of the bacteria are examined, with attention on how the […]

  • Investigation:  Mitosis and Cancer Cells

    Investigation: Mitosis and Cancer Cells

    The first part of this investigation, students examine slides of mitosis in an onion root tip and count the number of cells in each phase of the cell cycle.  An equation is then used to estimate the percentage of time the cell spends in each phase and students  create a bar graph to display results.  […]

  • Review with Whiteboard Panels

    Review with Whiteboard Panels

    In order to review for final exams and to also tie together the semester, I had my students create boards that summarized the labs they did during the semester.   I choose 6 labs so that each group of three would be able create a whiteboard panel and do a mini presentation to the rest of […]

  • Investigation:  Taste Buds and Signal Transduction

    Investigation: Taste Buds and Signal Transduction

    As a part of the chapter on cell signal pathways, students perform a lab that examines how their taste buds are affected by Gymnema.    For this lab, I simply placed a question on the board “How does Gymnema tea affect your ability to taste sweet foods?”    I provided them with a list of […]

  • Demonstration:  Can Yeast Digest Lactose?

    Demonstration: Can Yeast Digest Lactose?

    This activity can be performed as student lead inquiry lab or as a class demonstration activity.  Students should have a basic understanding of how enzymes work and the relationship between lactose and lactase.  If you use Openstax, this is a great lesson to bridge the chapter on enzymes to the next one on respiration and […]

  • Macromolecules: Sketchnotes

    In the past, I’ve had students create concept maps to help them organize the four macromolecules and related details.  This year, I modified the assignment to try to encourage the use of sketching to help students remember the details.  Students were asked to focus on one of the four macromolecules:  lipids, carbohydrates, nucleic acids, or […]
