Fifth graders explore osmosis as they watch organisms divide.  In this organism lesson, 5th graders use potatoes to experiment with the effects of salty water in the body.  Students discuss what osmosis is and record what...

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...

Young scholars are able to define the following terms: Osmosis, Isotonic Solution, Hypotonic Solution, Hypertonic Solution and Passive Transport. They read and complete a Mitosis worksheet, and play a Cell COmputer Game.

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson students observe osmosis and report their data using a graph. 

Students design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!

Students explore diffusion and active transport. They observe the effects of eggs in vinegar and predict what will happen when eggs are placed in corn syrup with food coloring. Students complete worksheets which lead them to describe...

Students examine and discuss the concepts of diffusion and osmosis. They observe the effects of diffusion on eggs by recording the change in an egg's size and the amount of liquid substance that remains.

Students explore principles governing diffusion and osmosis. Students perform a dialysis tubing experiment. They obtain core samples of potato in varying concentrations of sugar-water to measure water potential of the potato cells....

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 cells worksheet, students define 14 words associated with cells. They answer 12 short answer questions about the structure and function of the cellular system.

Young scholars microscopically observe various subcellular components. They determine the effects of different salt solutions on Elodea plant cells. Students explain the major function of a cell membrane and describe its structure.

Even though they were written for upper-level high schoolers or college pupils, the labs herein are possible to use even in middle school. In the activity, kids observe osmosis in both potatoes and elodea plants, then record and graph...

Students investigate osmosis, diffusion and a semi-permeable membrane. In this cell membrane lesson plan, students observe the movement of molecules out of a bag filled with sugar and starch into a beaker of water. They test the beaker...

Seventh graders study biological systems and how they reach equilibrium.  In this system balance lesson students divide into groups and complete an osmosis lab activity.

Students learn about cells. For this cells lesson plan, students take several days to learn about plant and animal cells and make their own edible cells with a cookie and icing.

Middle schoolers observe osmosis, a cellular process that normally can't be observed without a microscope, and use scientific method to observe osmosis in a chicken egg.

Students conduct various experiments on glucose. In this biology lesson, students differentiate the process of diffusion and osmosis. They test different foods for the presence of glucose and starch.

Fourth graders engage in this interactive instructional activity which illustrates diffusion and osmosis and shows them that molecules of life move dynamically and powerfully. They must analyze their lab orally and in writing.

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Students investigate atomic and nuclear structure of matter by researching historical atomic theories. Students examine Rutherford's studies and discover that many scientific conclusions change over time as new data is collected.

Students learn about the different structures that comprise cell membranes, fulfilling part of the Research and Revise stages of the legacy cycle. Students view online animations of cell membrane dynamics (links provided). Then they...

This lab will illustrate diffusion and osmosis through a semi-permeable membrane. A chicken egg will be used as the model cell, because the yolk is actually a single large cell. The surrounding egg white, or albumin, contains water and...
