Curated OER
Protoplast Production (Plant Cells Without Walls)
Students explore the spherical protoplasts of plants. Students observe that plant cells have a plasma membrane in addition to the cell wall. Students plasma membranes, solutes and organelles.
Curated OER
Chloroplasts
Students study chloroplasts, their structure and evolution. In this photosynthesis lesson plan students experiment with polarized light and the production of chlorophyll.

Osmosis and Dialysis
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 a potato...
Curated OER
Osmosis
Pupils 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 the...
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.
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.
Curated OER
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
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
Commonly Asked Questions on Vision and Color Perception
Students commonly ask question about vision and color perception which may be difficult to answer without taking. They use this module that contains a list of questions which often arise when biology students are studying the nervous...

Serc: How Do Different Liquids Affect Movement of Materials Across a Membrane?
Learners investigate the movement of different materials across the cell membrane of a raw egg once the egg shell has been dissolved in vinegar.

Alex: Rubber Egg Diffusion
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...
