Biodiversity and Evolutionary Trees
Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...
Cold Spring Harbor Laboratory
Mendelian Laws Apply to Human Beings
Why are so many inherited diseases more prevalent in populations of specified races? Scholars learn about pedigrees and genetics using a reading, an animation, primary sourced letters, a short video, a biography, a guided practice...

Using DNA to Explore Lizard Phylogeny
On the Caribbean islands, lizards expanded into different niches instead of competing for resources. Scholars discuss and learn from experts in a video how scientists prove the theory. They build phylogenetic trees based on appearances...
Howard Hughes Medical Institute
Beaks as Tools: Selective Advantage in Changing Environments
How does nature select some adaptations over others? Scholars experiment picking up seeds with two different types of tools simulating beaks. After practicing, they experience a drought where one type of seed suddenly isn't available....
Howard Hughes Medical Institute
Testing a Hypothesis
Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...
Cold Spring Harbor Laboratory
RNA Was the First Genetic Molecule
Can organic molecules come from a pre-biotic environment? Stanley Lloyd Miller proved it is possible when exactly the right conditions exist. Learn about his experiment and the other experiments later building off of it that changed the...

How Do Fibers Form?
The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...
Howard Hughes Medical Institute
Icefish Blood Adaptations: Viscosity
Most fish freeze to death when the water is too cold, yet some fish live in the Southern Ocean where the water is often below freezing. Scholars use two models representing the blood from most fish versus the blood from Antarctic fish....

Biochemistry and Cell Signaling Pathway of the Mc1r Gene
How do mice have so much fur color variation over generations? Scholars illustrate protein structures based on amino acid sequences. Then, they analyze the signaling pathway in different-colored mice populations. This allows them to...
Howard Hughes Medical Institute
Color Variation Over Time in Rock Pocket Mouse Populations
While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...
Howard Hughes Medical Institute
Molecular Genetics of Color Mutations in Rock Pocket Mice
Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...
Howard Hughes Medical Institute
Pedigrees and the Inheritance of Lactose Intolerance
What, exactly, causes lactose intolerance? Scholars view a video describing a Finnish study that determined why some people are tolerant while others are intolerant. They then use the data from the study to reenact the experiment and...
Howard Hughes Medical Institute
Fact Patterns: A Film Guide
What does it take to create a scientific theory? Learners attempt to answer the question by studying the work of Charles Darwin and Alfred Russel Wallace. While watching a video, they track observations from each scientist and then look...
