Diffusion and Osmosis Challenge
Challenge your biology class to analyze an experimental setup, in which a selectively permeable membrane separates two distinct solutions. They consider the concentration of the contents and answer ten questions pertaining to the...
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...
Curated OER
Investigating Osmosis
A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

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.
Curated OER
Diaper-Wipe Diffusion
Explore osmosis through art. Learners use paper towels and markers to create beautiful designs. Although a simple activity, the results are quite remarkable. Your class will love this lesson!

Osmosis, Diffusion, and Active Transport
No, it really is okay to play with your food! Emerging scientists manipulate popcorn, eggs, and other household objects as they demonstrate multiple cellular processes. The activity, capable of modifications, is designed to reflect the...
Curated OER
Osmosis
High schoolers investigate osmosis and diffusion in a liquid environment. In this osmosis lesson plan, students use dialysis tubing made into bags and filled with 3 different solutions. They observe the movement of water molecules into...
Curated OER
Osmosis and Diffusion
In this science worksheet, high schoolers investigate the cell and the process of osmosis and diffusion across the cell membrane and then perform an experiment.
Curated OER
Diffusion across a Selectively Permeable Membrane
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...
Curated OER
Basic Cell Structure
Initially, general details about cells and single cell organisms are provided. Next, the concentration becomes cellular processes such as respiration, osmosis, diffusion, fission and mitosis. This is an attractive PowerPoint which gives...
Curated OER
The Cell Membrane
Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...
Curated OER
Observing Osmosis
Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...
Curated OER
Osmosis and the Cell Membrane-part 2
Students participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

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
Osmosis
Fifth graders explore osmosis as they watch organisms divide. In this organism instructional activity, 5th graders use potatoes to experiment with the effects of salty water in the body. Students discuss what osmosis is and record what...
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
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
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....
