The Effects of Osmotic Balance and Imbalance In Living Cells
Learners 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...
Curated OER
EggCELLent Diffusion
Pupils 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.

Enhancing Uptake of Glucose in Rabbit Muscle Cells
Students observe diffusion of glucose through a cell membrane and research the function of chromium picolinate in glucose uptake into a cell. They conclude and understand the role of insulin and chromium picolinate in the uptake of...
Curated OER
Diffusion
Learners develop the concept of diffusion. In this science lesson plan, students demonstrate diffusion of molecules of matter in various states.
Curated OER
Cells Study Questions and Definition
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.
Curated OER
Plasmolysis in Elodea Plant Cells
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.
Curated OER
Cells
Students learn about cells. In 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.
Curated OER
Cell physiology and chemistry
Young scholars design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
Osmosis
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...
Curated OER
Sugar Solutions
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.

Observing Osmosis in a Chicken Egg
Tenth graders develop a hypothesis and explain what they observed on an activity. In this investigative instructional activity students observe osmosis and report their data using a graph.
Curated OER
Surface to Volume Ratios
Students measure the rate of diffusion and to calculate the surface area to volume ratios of varying cell sizes. The lesson is very clearly organized with a useful student worksheet provided. They perform a lab experiment which is...

Molecules Rock
Fourth graders engage in this interactive lesson 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.
Curated OER
Energy, Matter, and Organization
Tenth graders review the Energy, Matter, and Organization unit. They have one week to complete an essay. Students must submit a concept map or drawing. The activity is introduces by reading a short story line which presents a simple...

Osmosis Demonstration Lab
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...
Curated OER
Osmosis
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...

MITOSIS
Tenth graders examine the process of mitosis on a laser disc. They examine mitosis in an onion utilizing the microscope.
Curated OER
Discovering the Structure of the Atom
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.
