Genetics of Sickle Cell
This assignment was created for students who miss class and can be completed independently. There are sections to read with questions to answer, focusing on how DNA provides the instructions to make protein. A single base substitution in the gene that codes for hemoglobin results in sickle cell anemia. Students are walked through the process…

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…

Learn the Animal Cell
This animal cell coloring worksheet can be used with freshman biology for years as a supplemental way to learn the parts of the cell. I assign it as a review or reinforcement exercise. It’s also a good activity for rainy days and sub days. This version of the cell coloring includes a cell diagram that…

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.

Cellular Respiration Graphic Organizer
Students complete a graphic organizer that shows the process of cellular respiration.

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
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.

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…

Cell Labeling: Simple and Complex
Students practice labeling organelles on a simple model (2D) and a more complex model. The idea is for students to gain an appreciation for how cell diagrams are created. They don’t all look alike, and are often artistically created. Cell organelles tend to follow basic design rules, like the mitochondria will generally look like a…

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.
-
Cell Cycle Labeling
Students label the image of a cell undergoing mitosis and answer questions about the cell cycle.

DNA, Proteins, and Sickle Cell
In this activity, students use a codon chart to compare the DNA sequence of HbA (normal hemoglobin) to HbS (sickle cell). The DNA differs in a single base, where the codon for normal hemoglobin codes for glutamine, and the mutant form codes for valine.

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: 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…
