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...
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
Osmosis and Dialysis
How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...
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....

Thirsty Rocks: Please "Porous" a Drink!
A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...
Curated OER
The Membrane Potential
Give this summary of 16 pages of a text to your class to deepen understanding of cell permeability, diffusion, ions, and more. The handout portion includes vocabulary clarifications, detailed color diagrams, and important information;...
Curated OER
The"Dirt" on Soil
Learners examine the three different types of soil and their physical properties. In this soil lesson students design and implement a model of a water treatment plant.
Curated OER
Activity #4 Ground Water Model In a Jar
Students devlop a model, which they illustrate a water table and allow for the discussion of common terms and illustrate what those terms mean. They comprehend that a flow rates, removal of contaminants, and the amount of water stored...
Curated OER
Diffusion
In this diffusion worksheet, learners review the terms associated with diffusion and osmosis plus answer questions based on a passive transport lab they completed. This worksheet has 8 short answer questions.
Curated OER
Navvies/ Canals
High schoolers investigate the concept of water permeability in order to help find the best material to line a canal. The goal is to find a material that does not allow water to escape. They also conduct an experiment and record the...
Curated OER
What's The Level?
Students examine the movement of the water table and saturation zones. They describe the movements of the water table and locate the saturation zones. Students identify the function of each saturation zone. They develop a model of the...
