Dispersement of Particles: Diffusion and Osmosis

Beginning biologists explore passive transport through two demonstrations and a hands-on inquiry. Spray air freshener from one spot in the classroom and have class members raise their hands as the scent reaches them. Also, place a teabag...

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...

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...

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...

Do you have early finishers asking what they can do next, or any budding scientists eager to learn more about plant and animal cells? Then here is a cell unit for you! The packet provides scholars with everything they need in order to...

You may find this presentation helpful in setting up the classic experiment where potato wedges are used for observing the effects of osmosis. You can view the experimental setup in the text and a lab sheet in the pictures, but you will...

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...

Learning through osmosis doesn't work, but learning about osmosis is simple. A biology video provides a clear explanation of osmosis through simple diagrams and explains the application of osmosis in multiple contexts. 

Students distinguish between diffusion and osmosis and describe ways that drugs can be administered.  In this diffusion instructional activity students research career paths and create a presentation to give to the class. 

[Free Registration/Login may be required to access all resource tools.] The process of molecules moving from an area where there are lots of molecules to an area where there are fewer molecules is known as diffusion. The diffusion of...
