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
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Mystical Membrane
Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...

Introduction to Osmosis
A chicken egg is a very large cell—perfect for investigating osmosis! Scholars conduct an experiment with vinegar and eggs that helps them understand the process of osmosis. They follow the activity with an in-depth look at osmosis in...
Curated OER
Diffusion Across a Selectively Permeable Membrane
Students investigate how water passes through cell membranes. In this biology lesson, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.
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 Size Changes
Learners 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.

Bacterium Cell Label Me!
In this labeling a cross-section of a Bacterium cell worksheet, students use the glossary of Bacterium cell terms to help identify and label each cell part. Students label nine parts of the Bacterium cell.
Curated OER
The Plasma Membrane
In this plasma membrane worksheet, students will explore how cells are able to maintain homeostasis and the function of the plasma membrane. This worksheet has 6 fill in the blank and 7 true or false questions.
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
Understanding Cells
Students identify and define several related vocabulary terms. Students complete a short lab and complete the questions. Students create a cell crossword puzzle and play cell computer games through the included links.
Curated OER
Diffusion
Learners describe and illustrate the process of diffusion in selelctively permeable cell membranes. They are asked to respond to what they think will happen when food coloring is dropped in a bowl of water. Other activities will be...
Curated OER
Rubber Egg
Learners demonstrate the semi-permeability of a cell membrane. In this rubber egg lesson, students measure and record egg data, place the egg in jar with vinegar and close the lid, observe immediately and periodically for the next 3...
Curated OER
Cell 5 Diffusion and Osmosis
Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...
Curated OER
Osmosis and Diffusion: Egg Lab
Learners examine why diffusion and osmosis happen in an egg cell. In this diffusion lesson students demonstrate a semi permeable membrane.

Immune, Lymphatic System
A fantastic slideshow that has images, details, definitions and trivia to accompany each structure and response involved with the immune system. The slides are very useful for all levels of the immune response. A complete sets of notes...
Curated OER
Cell Transport
In this biology worksheet, 9th graders describe what osmosis is and how it explains the fact tat a watery syrup forms when you put sugar on strawberries. Then they describe how proteins made by ribosomes leave the cell. Students also...
Curated OER
The Effects of Osmotic Balance and Imbalance In Living Cells
Students investigate osmotic balance in living cells. In this osmotic balance lesson plan, students use elodea leaves to study the effects of salt solutions on the cell. They compare the changes in an elodea leaf with salt water on it to...

Generation of Action Potentials in Nitella Giant Algal Cells
Students observe cytoplasmic streaming in Nitella cells. They examine the conduction of a wave of depolarization across other membranes, such as the axons of neurons. Students predict the effects of sending a small electric current...
Curated OER
Osmosis
For this biology worksheet, students determine how many solvent and solute molecules there are in the red blood cell and the IV fluid. Then they determine whether the IV fluid is hypertonic, hypotonic, or isotonic to the red blood cell.

How Substances Get in and out of Cells
Although it contains some formatting issues, the Word document here contains good questions about osmosis and diffusion, and is easy to edit as needed. Designed as a study guide, you could use the information here for warmups, ideas for...
Curated OER
Bacterium Cells
In this bacteria worksheet, students read several elements of bacterium cells, their diet, types, locations, reproduction, resting stages, effects of, and classification. Students also study a cross-section of bacterium cells.
