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...

From the scientific method to the function of a cell, the eBook has it all. A useful resource provides a free biology textbook with a focus on context. The text begins with an overview of the process of scientific inquiry and biology...

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...

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...

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...

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 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...

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...

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.

In this osmosis activity, students put a strip of potato in three different solutions and document the changes in the potato to determine is the solutions were hypotonic, hypertonic, or isotonic. This activity has 6 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...

Students conduct an experiment with potato cores and a sucrose solution to investigate how salt water fish process water. They develop a lab report of their experiment.

Students create an animation of a cell process and insert it into a presentation. They choose a cellular process such as mitosis, osmosis or DNA replication, and create a simple 2D animation.

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.

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.

This site gives information about energy needed for desalination. It gives formulas on how to determine these figures.

Brief text summary of what students learn in the Diffusion across a Selectively Permeable Membrane lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Main teaching points include...
