Catalase: A Bioinformatics Case Study
Pupils investigate the physical structure of a protein by using a computer simulation tool. They record its primary amino acid structure while viewing it in three dimensions for a better visual recognition. There is also a comparison to...
Curated OER
Physiological Adaptations
Students investigate the concepts of genetics and how it is tied to the variations found within different species and how it is tied to adaptations. They review the theory of evolution and factors found to help create variation. The...

Consumers Get Energy From Other Living Things
How do plants and animals get their food? Learn about where energy comes from, how animals store energy, and aerobic respiration, in a lesson that allows scholars to diagram energy flows.
Curated OER
The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...
SRI International
Nanofiltration
How can everyone in the world have access to clean drinking water? Throughout the lesson, learners read about and listen to how water is filtered, what the filtration process removes, and the best ways to filter. They explore the...

Taxonomic Keys
Seventh graders create their own dichotomous key. In this biology lesson, 7th graders classify animals based on their observable features. They explain how to use their dichotomous key.
Curated OER
Natural Selection in Action
Students demonstrate natural selection through a lab activity. In this biology instructional activity, students explain how natural selection leads to speciation. They complete their lab report and discuss results in class.
Curated OER
Consider the Issues
Learners develop and express opinions on personal and societal issues in biology through journal entries (written and other forms), oral position statements and group discussions.
Curated OER
What Happens When A Cell Divides?
Students investigate the cycle of mitosis. In this biology lesson plan, students discuss the different stages of mitosis through cell reproduction. They further their investigation through laboratory analysis.
Curated OER
Cell Reproduction and Inheritance
Pupils determine their inherited characteristics from their parents. In this biology lesson, students study the life of Mendel using an interactive website. They differentiate dominant and recessive characteristics.
