The Case of Darwin's Finches
One of the most striking pieces of evidence for Darwin's Evolution of Species was his observations of finches and how their beaks differed from island to island, depending on their primary food sources. So what would happen to the theory...

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....

Cell Division
Searching for simple ways to teach mitosis to high schoolers? Using colored chalk and onion root tips, pupils visually demonstrate what they view when looking through the lens of a microscope. There are also various ways to expand the...

The Molecular Biology of Mutations and Muscular Dystrophy
Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

Soap Opera Genetics – Genetics to Resolve Family Arguments
Did she cheat on her husband? Did the hospital switch the babies? Should they have children? As much as this sounds like the plot for a soap opera, all of these questions fit into a single lesson on genetics. Scholars read about three...

Clay Planets
Why do scientists use models? In the first installment of 22, groups create scale models of our solar system. They then share and discuss their models.
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!

Study Guide for Chapter 12: The Cell Cycle
In this biology worksheet young scholars map out and describe the process of mitosis for the nine questions. The last four questions are several combined in each.
Curated OER
Mitosis & Cell Processes
Young scholars research the process of mitosis and how it progresses to the finished result of cell division. They reflect upon how this causes organisms to grow larger and helps tissues to be renewed.
