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...

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 lesson 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...

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...

In this diffusion through a membrane worksheet, high schoolers 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...

Students 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 instructional activity, 7th graders see how and why cells use cellular respiration. They see a cellular respiration recipe on the SMART board and watch as...

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.

Students 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 sprays...

In this crossword puzzle worksheet, students read the clues that relate to diffusion and osmosis. Students then complete the 20 question crossword using the given clues.

In this biology instructional activity, students locate and identify various vocabulary terms relating to cells and microscopes listed on the right. There are 26 biology terms located in the word search.
