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...

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...

Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

Teach your class how to get out of a cell — or break in. The third installment in a seven-part series introduces the class to cell membranes and their functions. The lesson plan includes information to present to the class,...

I can move about freely, but you cannot. The class models the movement through cell membranes by way of passive and active transport. Members of the class play the roles of various proteins, atoms, compounds, and cell actions and mimic...

Young scientists demonstrate their understanding of cell transport on this comprehensive instructional activity. Focusing on cellular structure and the different processes that allow materials to move into, out of, and...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

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...

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....

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...

Students study diffusion and how it applies to the human body.  In this diffusion instructional activity students complete a lab activity and discuss what they learned. 

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;...

Students investigate the concept of diffusion and how materials enter and leave a cell. In this movement across a membrane lesson plan, students use perfume, food coloring in water and a sugar cube in water to observe diffusion. They...

High schoolers 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...

In this diffusion through a membrane instructional activity, students fill in the blanks to complete 27 statements about cell membranes, the movement of molecules across the cell membrane, concentration gradients and diffusion.

Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

Students apply the science of chemistry to soil and plant relationships. They define diffusion and indicate for which of these nutrient(s) would you expect diffusion to be the most important for movement to the plant root? Pupils...

High schoolers calculate the SA/V ratio and volume of phenophthalien agar that are cut into different shapes. They then let ammonia diffuse into the various pieces of agar and determine the effect that SA/V had on the rate of diffusion.

Students demonstrate Graham's Law by observing a gaseous diffusion. After a lecture/demo, students perform an experiment then complete a write up activity which is imbedded in this plan to reinforce what they have observed during the...

Students investigate how water passes through cell membranes. In this biology instructional activity, students differentiate osmosis and diffusion. They illustrate the movement of water in both processes.

Sixth graders read the book My Great-Grandmother's Gourd and answer short answer questions about the change of culture in the book. In this culture lesson plan, 6th graders discover culture diffusion, invention, and innovation.

Seventh graders explore science topics using a SMART board. In this respiration lesson, 7th graders see how and why cells use cellular respiration. They see a cellular respiration recipe on the SMART board and watch as the cells produce...

For this transport worksheet, high schoolers compare and contrast the characteristics and examples of active transport and passive transport. This worksheet has 1 graphic organizer and 11 short answer questions.

High schoolers are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher...
