  • Use Beets to Explore Membrane Permeability

    Use Beets to Explore Membrane Permeability

    Students test the effects of pollution on membrane permeability using beetroot cores.

  • Brazilian Wasp Venom Kills Cancer Cells  – CER

    Brazilian Wasp Venom Kills Cancer Cells – CER

    Students complete an CER on how Brazilian wasp venom can disrupt the cell membrane of cancer cells which can potentially be used to treat disease.

  • Cell Membrane Transport Graphic Organizer

    Cell Membrane Transport Graphic Organizer

    Label a graphic that compares the types of transport in a cell, such as osmosis, diffusion, and active transport.

  • How Do Legionella Bacteria Cause Disease?

    How Do Legionella Bacteria Cause Disease?

    Analyze a graphic that shows how legionella bacteria are taken up by cells through phagocytosis and reproduce in the phagosome.

  • Investigation: Determine Molarity of Unknown Solution

    Investigation: Determine Molarity of Unknown Solution

    Students determine the mass of water beads after soaking them in solutions. They use the change in mass to determine the molarity.

  • Case Study: Cystic Fibrosis Mutations

    Case Study: Cystic Fibrosis Mutations

    This case study is a follow-up to the Cystic Fibrosis Case Study where students explore how changes in transport proteins affects the movement of ions, resulting in a build-up of chloride ions and the symptoms of the disease. Students were introduced to the idea that different mutations can cause differences in the transport proteins, but…

  • Osmosis Practice with Slides

    Osmosis Practice with Slides

    Practice identifying hypotonic and hypertonic solutions and determining which direction water will flow with these slides. You can assign this activity on Google Classroom, and students can complete the activity on their own or in groups. The activity features 4 slides with cells in various solutions of glucose or glucose + sodium. Next to each…

  • Reinforcement: Cell Transport

    Reinforcement: Cell Transport

    This reinforcement worksheet was designed for introductory biology, to help students learn concepts related to cell transport across the membrane. Words include osmosis, diffusion, hypertonic, and hypotonic, semipermeable, and active and passive transport. The exercise has vocabulary terms and a list of sentences or definitions for students to match to the words. I use google…

  • Cell Membrane Coloring

    Cell Membrane Coloring

    Color the cell membrane with a focus on diffusion, osmosis and transport proteins. Students color the structures of a cell membrane according to the directions. Then they answer questions about cell transport. I designed this worksheet for an introductory biology course to reinforce concepts related to cell transport. An image shows the phospholipid bilayer with…

  • 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.

  • Cell Structures: A Graphic Organizer

    Cell Structures: A Graphic Organizer

    This graphic organizer (concept map) organizes the cell structures around three main parts of the eukaryotic cell: the nucleus, cytoplasm, and cell membrane.

  • 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…

  • Cell Membrane and Transport

    Cell Membrane and Transport

    This reinforcement worksheet displays a graphic of the cell membrane showing the phospholipid bilayer and embedded proteins.    Students identify structures within the bilayer and use reasoning to determine how molecules are moving across the membrane in response to a hypertonic solution. Worksheet was designed for freshman level biology classes who are studying osmosis and…

  • Case Study – Cystic Fibrosis

    Case Study – Cystic Fibrosis

    This case study explores the relationship between the cell membrane and breathing difficulties that occur as a result of the genetic disorder cystic fibrosis.

  • Student Guide to Frog External Anatomy

    Student Guide to Frog External Anatomy

    Lab handout over the external anatomy of the frog. Can be used as part of a frog dissection unit. Includes instructions and images to label.
