Curated OER
Investigating Factors That Affect Cell Membrane Permeability
Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...
Curated OER
Modeling the Cell Membrane
In this membrane permeability activity, students read introductory information about the cell membrane structure as it pertains to permeabillity and draw a representation of the membrane as they complete a lab. Students record the...
Curated OER
Cells and the Cell Membrane
Students investigate the properties of cell membranes by isolating the membrane surrounding chicken eggs. They set up an experiment by placing eggs in a vinegar solution for three days. A powerpoint lecture emphasizes the structure of...

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...
Curated OER
Investigating Osmosis
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...

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)
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...
Curated OER
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology lesson, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Osmosis and Diffusion: Egg Lab
Students examine why diffusion and osmosis happen in an egg cell. In this diffusion lesson students demonstrate a semi permeable membrane.
Curated OER
Understanding Cells
Students identify and define several related vocabulary terms. Students complete a short lab and complete the questions. Students create a cell crossword puzzle and play cell computer games through the included links.
Curated OER
Study of the Cell
Students draw a diagram to show the fluid mosaic model of a membrane. They explain how hydrophobic and hydrophilic properties help membranes hold their shape. They identify the functions of different cell membrane proteins as well.
Curated OER
Cell Community
Seventh graders use technology to review cell structure and function. In this cells less, 7th graders review the parts and functions of a cell, and use photography/video and PowerPoint to enhance their explorations.
Curated OER
An Egg-cellent Osmosis Experiment
Students investigate the problem of osmosis by conducting an experiment. They use eggs with the shells dissolved to tell whether fluid can move across the membranes. The experiment provides high interest for all kinds of students to keep...

What is DNA? DNA Extraction from Kiwifruit
Learners isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.
