Biomolecules
An informative lesson has learners read about, discuss, and study the classification, structure and importance of the following biomolecules: carbohydrates, proteins, lipids, nucleic acids, and enzymes.Â

Inquiry into Consumer Products
Students recognize different consumer products, found in and around the home, that have reactive or denaturing properties when used together. They explore chemical and physical properties of each product by identifying chemical formulas...

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....

Wolves: DNA Pawprinting
A mystery canine was shot and killed near Yellowstone National Park in the early '90s. Genetics whizzes explain how they might go about identifying whether the animal was a true grey wolf or a hybrid. A drawing of the animal's DNA bands...
Curated OER
Pesticides and Eggshell Thinning.
Students analyze the calcium content of egg shells as an introduction to the toxic effects of pesticides on biological systems.
Curated OER
Risk Factor Roulette
Students examine "multiple chemical sensitivity" and how it relates to genetic variation and environmental factors. They read an article, conduct research, and identify risk factors related to chemical sensitivity, asthma, breast cancer,...
Curated OER
Funky Fungus
Students discuss decomposition, bacteria, fungi and other microscopic organisms. They participate in an experiment to grow fungus on bread. As the fungus colonies grow, students observe them under a microscope to identify and locate...

Microorganisms: Good Guys or Bad Guys?
Students discover the role microorganisms play in our lives. In this decomposition instructional activity, students examine decaying foods and plants in order to analyze the different bacteria that grows. Students discuss the good and...
Curated OER
Genetic Engineering/Biotechnology
Pupils create a paper model of a plasmid and insert a DNA molecule that contains a specific gene into the plasmid. They complete an actual transformation involving E. coli bacterium and relate the two activities to one another.

"Who Done It?" Analysis of Molecular Fingerprints Left At the Scene of the Crime
Learners examine different types of DNA fragments. They record and analyze their results. They determine who is the criminal in the story.
Curated OER
Wolves: DNA Pawprinting
Learners explore and research the most widely distributed terrestrial carnivore, the wolf. They critique the true mystery of this animal and then form an opinion about this creature. The restriction-site analysis of mitochondrial DNA is...
Curated OER
Rotten Truth
Students complete activities to study decomposition. In this decomposition lesson, students work in pairs to observe a decay buffet experiment. Students keep compost bag journals. Students define and discuss the process of decomposition.
Curated OER
What's on Your Plate?
Students demonstrate the path of food in the body. In this biology lesson, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
