Digestive Concept Map
Students use this concept map to reinforce their understanding of the digestive system and how structures within that system are related. The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down food. The esophagus is a muscular tube that connects the mouth to the stomach. The…

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
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…

Anatomy of the Heart by Number
In this exercise, read about the structures of the heart and how blood flows through the systemic and pulmonary circuit. The text describes each structure (by number), you label with the names of the vessels and chambers of the heart. Use arrows to trace the flow of blood from the body, to the heart, then…

The Lion in Your Living Room
A video worksheet to follow the documentary The Lion in Your Living Room. Includes multiple choice questions to keep students focused while watching the film.

How is Glucose Taken Up by Cells?
This worksheet takes a closer look at the cell membrane and how insulin binds to the receptor on the cell membrane which creates a signal cascade, resulting in the movement of the Glut-4 transport protein to the surface of the cell. Students interpret a graphic showing the membrane, receptors, and the Glut-4 transport protein.

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.
-
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.

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.

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…

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.
-
Investigation: How Can Diffusion Be Observed?
This investigation provides a hands-on way to observe what happens when a chemical moves across a semipermeable membrane. In this case, a cheap plastic bag serves as a model for the cell membrane and shows that iodine will move into the bag and turn the contents purple.

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.

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.
