Evolution of Fur Color in Mice – Mutation, Environment and Natural Selection
Most species of animals include a variety of fur or hair color, but why? Scholars watch a video about a changing environment for mice. As the rocks around them change hues, different colors of mice begin to thrive. Discussion questions...

How Do We Sense the Flavors of Food?
We taste with our taste buds, so why do flavors change when we have a stuffy nose? Scholars experiment with taste testing while holding their noses and then while smelling. They record their observations in pairs and come together to...

Understanding El Niño Using Data in the Classroom
Are weather troubles caused by El Nino? An installment of a larger series presents a five-part lesson on El Nino. First, scholars learn to read sea surface temperature maps. Then, they compare them to data on graphs before determining if...
Harvard University
Cosmic Questions
Scholars learn the stories of the universe with a unit study on the cosmos. They model the universe, learn about the relationship with the electromagnetic spectrum, understand the big bang theory, and debate the existence of life on...
NOAA
Investigating Sea Level Using Real Data
The news reports on rising sea level, but how do scientists measure this rise? Scholars use NOAA data including maps, apps, and images to work through five levels of activities related to sea level. Each level in the series adds a new...

Finding the Crater
A mass extinction event caused by an impact usually leaves a crater. Scholars use data from 10 different sites around the world trying to determine where to look for the crater. They use data, listing the amount of various minerals to...
Howard Hughes Medical Institute
The Making of a Theory—Fact or Fiction
Two scientists, two independent studies, two similar theories! A video lesson presents the work of Charles Darwin and Alfred Wallace that led to their theories on evolution. Scholars then evaluate statements and provide evidence to...
