Color Vision Genetics Evolution Simulation
At one point, all mammals carried only two color receptors, but now most humans carry three. An informative presentation and hands-on activity demonstrate how this evolved through genetics. By participating in the activity, pupils...

Looking Into Lactase: Guided Inquiry
Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Fibers, Dyes, and the Environment
Nanofibers can be made through electrospinning or force spinning in order to reduce the negative impact on the environment. Pupils study the role of fibers and dye on the environment through a series of five hands-on activities. Then,...

The Tide is High, but I’m Holding On… Using ICESat Data to Investigate Sea Level Rise
Based on the rate of melting observed from 2003-2007 in Greenland, it would take less than 10 minutes to fill the Dallas Cowboys' Stadium. The 17th instructional activity in a series of 21 has scholars use the ICESat data to understand...

Conductors and Insulators
Why did the orchestra director use a copper baton? She heard it makes a great conductor. Scholars select six items to test in a circuit to determine if each is a conductor or an insulator. Clear instructions for using electricity allow...

Quantifying Land Changes Over Time Using Landsat
"Humans have become a geologic agent comparable to erosion and [volcanic] eruptions ..." Paul J. Crutzen, a Nobel Prize-winning atmospheric chemist. Using Landsat imagery, scholars create a grid showing land use type, such as urban,...

Is It Getting Hot in Here, or Is It Just Me?
Currently, only 2.1% of global warming is felt on continents, while over 93% is felt in the oceans. The fourth lesson in the series of 21 on global warming is composed of three activities that build off one another. In the first...

John Travoltage
Did you get to play with electric currents or were you grounded? An electrifying simulation shows how building up a charge of electricity creates a static shock once grounded. Pupils rub John's foot across the carpet and view the buildup...

Conceptualizing Module III
Many researchers focus on one impact of climate change in isolation, but researchers gain a global perspective when they come together. A timely lesson teaches scholars about the projected impacts of global temperature increases. Then...

When It Rains It Pours More Drought and More Heavy Rainfall
Which is worse — drought or flooding? Neither is helpful to the environment, and both are increasing due to climate change. The 16th lesson in a series of 21 covers the average precipitation trends for two different climates within the...

Wherefore Art Thou, Albedo?
In the sixth lesson in a series of 21, scholars use NASA data to graph and interpret albedo seasonally and over the course of multiple years. This allows learners to compare albedo trends to changes in sea ice with connections to the...

Forces in 1 Dimension
A realistic simulation uses charts to show forces, position, velocity, and acceleration versus time based on how the simulation is set up. Once those concepts are mastered, scholars use free body diagrams to explain how each graph...

Faraday's Law
Could a flux capacitor really work? An engaging simulation encourages scholars to investigate Faraday's law. They experiment with various speeds, magnitude, voltage, and different-sized coils. Hopefully experimenters will be able to...

Quantifying Land Changes Over Time in Areas of Deforestation and Urbanization
Is qualitative or quantitative research more convincing when it comes to climate change? In the eighth lesson during this 21-part series, scholars begin by performing a quantitative analysis of deforestation and urbanization. Then, they...

Get Your Techno On
Desert regions are hotter for multiple reasons; the lack of vegetation causes the sun's heat to go straight into the surface and the lack of moisture means none of the heat is being transferred into evaporation. This concept, and other...

Planet Designer: Retro Planet Red
What does the atmosphere on Mars look like? This fourth lesson in the series of five is designed for high schoolers. Scholars apply previous knowledge to add atmosphere to Mars in an online simulation. This comprehensive lesson includes...

The Making of the Fittest: Natural Selection in Humans
Sickle cell disease only occurs when both parents contribute the trait, and mostly in those of African descent. Where did it come from? How did it evolve? Tony Allison, a molecular biologist, noticed a connection between sickle cell and...
