Curated OER
Semipermeable Membranes and Bioaccumulation
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....
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...

Cell Structure
Your accelerated biology learners will add to their understanding of cell structure with this resource. Taking them beyond the basics of mitochondria and chromatin, it also queries them about actin microfilaments and the extracellular...

Review of Cell Organelles
In this cell organelles learning exercise, students read the structure and function of different plant and animal cell organelles to determine what organelle is being described. Students write in the 15 organelles into a chart.
Nuffield Foundation
Observing Osmosis, Plasmolysis, and Turgor in Plant Cells
Create the perfect conditions for osmosis. Young scholars use a microscope to observe plant cells exposed to distilled water or sodium chloride. They observe how osmosis creates turgid or plasmolyzed cells.
Curated OER
Cell (Biology)
Students conduct a series of activities to explore the nature of cells. In this biology instructional activity, students observe plant and animal cells under the microscope and compare them. They differentiate osmosis and diffusion.
Curated OER
Acting Potential
Students set up a cell membrane with the material provided by their teacher and then arrange beads properly to show how the sodium and potassium ions are arranged. They then make a model representing the axon of a neuron.
Biology Junction
Introduction to Biology
Welcome to Biology! Introduce pupils to a subject conceptualized by Aristotle in 300 BC through a presentation and worksheet. It covers the themes of biology, characteristics of life, the scientific method, microscopes, and measurements.

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
Tour of the Cell 1
Each of these slides deals with an individual organelle and displays a diagram along with labels of the structures. The most useful components of this slideshow are the summaries of functions and descriptions of how the organelles are...
Curated OER
Review of Cell Respiration
In this cellular worksheet students complete a series of multiple choice questions on cell respiration, proteins and photosynthesis.
Curated OER
The Cell
Students visualize plant and animal cells, explain the parts of a cell and their functions and distinguish plant cells from animal cells. Working Students, in groups, must present a particular portion of a cell to the entire class.

7.012 Fall 2004 Section Self-quiz
This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

AP Biology Lab Review
A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...
Curated OER
The Cell Cycle: Cell Growth, Cell Division
Help your students understand cell division. Explore the topics of mitosis by examining the details of chromosomes at interphase, metaphase, anaphase, prophase, and telophase. Wonderful slides will keep your students' attention while...
Curated OER
Extracting DNA from Your Cells
Three steps are needed to extract DNA from learners' inner cheek cells. The procedure and reasons for each step are explained. As enzymes work on the cells, a series of questions are answered regarding the structure of the DNA molecule....
Curated OER
Cell Size Changes
Students examine the behavior of living cells treated with different types of stimuli. They watch an online movie, examine wet mount slides under a microscope, take an online quiz, and analyze data.

How Can We Study the Differences in Animal and Plant Cells Using the Compound Microscope?
Students examine their cheek cells with a compound microscope. They identify different parts of the cell. They compare and contrast animal and plant cells with the microscope as well.

Viral DNA Integration
How do viruses hijack our cells to produce more viral particles? Junior immunologists model how viral RNA integrates into a host cell's DNA using pop beads and use interactive tools to explore a virus' genome. The teacher's guide...
