Half Life Lab
Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
Curated OER
Are You Gellin
Students conduct an investigation of differentiating between different types of DNA. This is done with a simulation activity of being a scientist in charge of selling different sets of DNA for research which requires different...
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...

Pasta Genetics
Four different-shaped and dyed pasta types represent four different alleles. Following a guide sheet, young geneticists practice randomly selecting alleles and discover the traits of the resulting offspring. This is a fun and solid...
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
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.
