Basic Cell Structure

For Teachers 7th
Initially, general details about cells and single cell organisms are provided. Next, the concentration becomes cellular processes such as respiration, osmosis, diffusion, fission and mitosis.  This is an attractive PowerPoint which gives...

How do Hypotonic, Hypertonic, and Isotonic Solutions Affect the Water Movement of a Cell?

For Teachers 7th - 12th
After removing the shell from a raw egg, cell biologists soak the egg in either a hypotonic, hypertonic, or isotonic corn syrup solution. They calculate the percent change in mass and compare it to the strength of the solution in a...
Lesson Planet

Semipermeable Membranes and Bioaccumulation

For Teachers 7th - 12th
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....

WET Science Lesson #5: Pass the Salt Please! (How Road Salt Affects Wetlands)

For Teachers 7th - 12th
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...

Passive Transport

For Students 9th - 12th
Not only will beginning biologists write the answers to questions on this worksheet, they will analyze diagrams of what happens in different situations considering cell transport. Although you will find the text a little blurry and one...

Osmosis and Plant Cells

For Students 7th - 12th
Aside from obviously being a photocopy and a couple of minor formatting problems, this is a laudable lab activity for exploring osmosis. Biology groups cut potato chunks into equal volumes and record the mass of each. They place two...

AP: Chapter 8: Membranes

For Students 9th - 12th
AP biology buffs dismantle the mystery of the cell membrane by explaining its structure and function. They decipher membrane fluidity, define the roles of membrane proteins, and analyze a diagram of a selectively permeable membrane...
Lesson Planet

AP Chapter 9: Respiration - Extra Credit 3 Peter Mitchell & How Cells Make ATP

For Students 10th - Higher Ed
Critical thinking is required to answer these five questions on cellular respiration. Advanced biology learners consider transport across the mitochondrial membrane and the metabolic pathway in ATP synthesis.

Membranes

For Students 9th - Higher Ed
Biology pupils take the cell membrane apart piece-by-piece as they complete this worksheet. They describe the structure of the cell membrane and explain the processes that transport materials across it. This phenomenal resource even has...
Lesson Planet

The Cell

For Students 8th - 12th
Critical thinking questions accompany a data chart and vocabulary terms about cell structure and function. By completing this two-page worksheet, your class reviews fundamental concepts about the cell. Though it was intended as a chapter...
Lesson Planet

Starch

For Teachers 7th - 12th
Students examine the basics of starch and how it is used in food. In this photosynthesis lesson students experiment with variables that affect starch production in photosynthesis.
Lesson Planet

Diffusion and Osmosis Challenge

For Students 9th - 12th
Challenge your biology class to analyze an experimental setup, in which a selectively permeable membrane separates two distinct solutions. They consider the concentration of the contents and answer ten questions pertaining to the...
