Structure and Function of Cell Membranes
Lead your high school class on an exploration inside the cell. Individuals investigate the relationships between cells structure and function given their relative locations on the cell membrane. They explore the concept of homeostasis...
Curated OER
Diffusion across a Selectively Permeable Membrane
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...

Comparing Plant and Animal Cells
In this comparing plant and animal cell worksheet, students use a microscope to observe cheek cells and onion cells. They compare their observations and answer 3 questions about their discoveries.
Curated OER
Biology: Cells and Chemical Changes
Students explore the numerous functions of cells in both plants and animals. Following a pre-assessment, they construct cell models and examine onion cell slides stained with iodine or dye. After participating in experiments on how to...

Cells Are Us
Students explore cells. In this science lesson plan, students investigate how the cell is the basic unit of life, that cells divide slowly to become mass of cells, and that there is a gradual loss of cells throughout life.
Curated OER
The Cell: Unit of Life
Students identify the parts of plant and animal cells, how samples can be obtained and what the differences are.

Diffusion Through a Membrane
In this diffusion through a membrane worksheet, students fill in the blanks to complete 27 statements about cell membranes, the movement of molecules across the cell membrane, concentration gradients and diffusion.
Curated OER
Observing Osmosis
Students investigate osmosis using egg cells with the shells removed. In this osmosis lesson plan, students remove the shell of an egg by letting it soak in vinegar for two days. They take measurements and observe the cell. They soak the...
Curated OER
Movement Across the Membrane (Diffusion)
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...
Curated OER
Cells, The Structural and Functional Units of Life
Pupils observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.
