Investigating Factors That Affect Cell Membrane Permeability
Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Structure and Function of Cell Membranes
Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...
Curated OER
Cell Size and Shape; Diffusion and Osmosis Processes
Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Cell Parts
What do a bird, an egg, a rabbit, and a toad all have in common? This fun-filled resource explains the similarities and differences between cells and how all cells are similar, yet all are different. Learners begin by depicting a...
Curated OER
Dissecting Frog Embryos: Cell Membranes and Mitosis
Students use high powered dissection microscopes to dissect and examine frog embryos as well as see balls of cells that were produced by rapid division. The concept of mitosis links to the lesson.
Curated OER
How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...
Curated OER
String Cells
Use this resource to have your class learn about the cell. This resource walks learners through the construction of a model of a cell. This project is completed in a cooperative learning group, and reinforces the higher-order...
Curated OER
Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

Observing Osmosis, Plasmolysis, and Turgor in Plant Cells
Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.
Curated OER
Cell (Biology)
High schoolers conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Acting Potential
Students set up a cell membrane with the material provided by their teacher and then arrange beads properly to show how the sodium and potassium ions are arranged. They then make a model representing the axon of a neuron.

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)
As an anticipatory set, biologists listen to the story of Ruth Patrick, a scientist who used algae to detect water quality. They observe a demonstration of osmosis and diffusion. In their lab groups, they place Elodea stalks in...
Curated OER
The Cell
Young scholars visualize plant and animal cells, explain the parts of a cell and their functions and distinguish plant cells from animal cells. Working Students, in groups, must present a particular portion of a cell to the entire class.
Curated OER
Cell Size Changes
High schoolers examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.
Curated OER
How Can We Study the Differences in Animal and Plant Cells Using the Compound Microscope?
Students examine their cheek cells with a compound microscope. They identify different parts of the cell. They compare and contrast animal and plant cells with the microscope as well.
Curated OER
PROTOPLAST PRODUCTION
Students are allowed to strip away the cell walls of plants cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). They see that plants cells indeed have a plasma membrane in...
Curated OER
Cell Swelling and Shrinking
Students examine the concept of osmosis in relation to dehydration. They identify the function and structure of semi-permable membranes. They predict how certain processes can affect the characteristics of an organism.
Curated OER
Cytoskeleton of a Cell
Students examine the cytoskeleton of a cell. They work together to build a structure with a certain number of materials. They share their "cell" with their classmates.
Curated OER
A Cell Is Like A City
Students create analogies that help them remember the cell parts as well as their respective functions.
Curated OER
Cell Cookie Lesson Plan
Students review the structure and fuctions of plant and animal cells. They use various types of materials such as sugar cookies and cake frosting for this instructional activity.
Curated OER
Parts of the Cell
Students examine plant and animal cells to observe the organelles present in the cell, to match the function of each to the organelle on a cell model and to build a model of the plant or animal cell.
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.

Cell Theory Rap
All that this will link you to is a rap about cell theory and organelles. Use it as an example for a creative assignment in your biology class. Divide the class into groups and assign them a topic for which they write and perform a skit,...

Using Molecular and Evolutionary Biology to Understand HIV/AIDS and Treatment
HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...
