Curated OER
Cell physiology and chemistry
Young scholars design an experiment to discriminate between chemical diffusion, osmosis, facilitated diffusion and active transport through a membrane. Be specific about predictions and interpretations!
Curated OER
Cell Cookies
Fifth graders, in groups, create a plant or animal cell out of cookies, frosting, and candy pieces.

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...
Curated OER
Cell-ebrations in Science
Students recognize that all living things are made up of cell and that they cannot easily be seen by the naked eye. Students become familiar with the use of microscopes as a tool for investigation.
Curated OER
Schools and Cells
Fourth graders create analogies in poster format between a cell's organelles and their school. For example, 4th graders coul say a cell's mitochondria is like the cafeteria, both are a source of energy.
Curated OER
Fighting Infection
Students study immune responses and the structures that are related to immune cells functions. In this fighting infection lesson students construct antibody complexes and model the interaction of the immune system when it is...

Prokaryotes
Lead your biology class on a cell-sized adventure! Emerging scientists construct models of prokaryotes, then design an experiment to properly grow a bacterial culture. They conclude the activity by viewing the culture under a microscope....
Curated OER
Extraction of DNA from Onion
Young scholars experiment with DNA by isolating it from plant tissue. They investigate whole onions to prepare DNA. They complete the experiment to examine the structural characteristics of DNA.

The Keepers of the Gate Challenge
Help your class make a connection between salt water and nanoscience. In the introductory activity of a seven-part unit, the class explores why salt water helps a sore throat feel better. Pupils conduct preliminary research about the...
Curated OER
The Great Archeological Dig
Learners explore biology by identifying a diagram. In this cell anatomy lesson, students read a story about archeology and conduct a fictitious archeology dig in class in which they search for animal cells. Learners define a list of...
Curated OER
Protists - The Protozoans
Five pages provide thorough coverage of three protozoans: euglena, amoebae, and paramecia. For each, junior biologists read factual text, label the organism, and write answers to several questions. This neatly organized assignment is...
Curated OER
EGG MAZE: COUNTING BY TWOS, THREES AND FIVES
Students successfully count by twos, threes and fives, using pictures of eggs and poultry as points of interest. They orally review the types of counting (twos, threes, or fives). Students are introduced the idea of a dozen eggs.
Curated OER
Rubber Egg
Students demonstrate the semi-permeability of a cell membrane. In this rubber egg lesson plan, students measure and record egg data, place the egg in jar with vinegar and close the lid, observe immediately and periodically for the next 3...
Curated OER
Using Microscopes
Students do an experiment using a microscope. In this lesson, about cells, students examine different slides using a microscope. Students look at an onion skin, cheek cells, and potato cells. In each of these, students find cell walls,...
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
DNA Extraction
Students are able to extract and observe a visible amount of DNA from Escherichia coli cells. They discuss the properties of DNA. Students confirm the presence of DNA by a reaction with an indicator.
Curated OER
Molecular Recognition and the Immune Response
Learners explore the importance of molecular shape and charge in molecular-recognition. They examine the interaction between antigens and antibodies. Students design and build 3-D visual models to represent molecular-recognition...
Curated OER
Your Body's Defenses When Microbes Attack
Students study how being exposed to a harmful microbe doesn't automatically make them ill. They discover the lines of defense against microbe invaders and explore the roles of skin and mucus membranes, white blood cells, and lymphocytes...
Curated OER
How Genes Work Lesson Plan
Students define the key terms that are the structure and function of DNA. In this genetics lesson plan students complete a lab activity in which they construct a model DNA structure.
Curated OER
Chloroplasts
Students study chloroplasts, their structure and evolution. In this photosynthesis lesson students experiment with polarized light and the production of chlorophyll.
Curated OER
A Hands-On Paper Activity Examining The Relationship Between Hierarchical Levels Of Structure And Function
Students investigate how complex functions arise in biological systems through the creation of several paper structures to accomplish various tasks such as remaining suspended in air for the longest time, making the loudest noise and...
Curated OER
Surface to Volume Ratios
Students measure the rate of diffusion and to calculate the surface area to volume ratios of varying cell sizes. The lesson is very clearly organized with a useful student worksheet provided. They perform a lab experiment which is...
Curated OER
Teaching Multiple Alleles
Students view a simple ABO blood system for the introduction of this subject using concrete models of eythrocytes (red blood cells, or RBC's), antigens, and antibodies. They can physically see the antigens that result from certain...
Curated OER
How do things flow in and out of a cell?
High schoolers revise thier partner's essay. They also write the second draft of their essay for homework. Students use the Protein Explorer web site to visualize molecules, ATP, DNA, proteins and lipid bilayer. They are able to see...
