During this module, students take a virtual mobile lab drive with scientists to investigate and learn about atmospheric carbon gases, their sources, and impacts on air quality.
Move point charges around on the playing field and then view the electric field, voltages, equipotential lines, and more. It's colorful, it's dynamic, it's free.

This new version of the CCK adds capacitors, inductors and AC voltage sources to your toolbox! Now you can graph the current and voltage as a function of time.
Build circuits with capacitors, inductors, resistors and AC or DC voltage sources, and inspect them using lab instruments such as voltmeters and ammeters.
An electronics kit in your computer! Build circuits with resistors, light bulbs, batteries, and switches. Take measurements with the realistic ammeter and voltmeter. View the circuit as a schematic diagram, or switch to a life-like view.

Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.
Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.
Humans have been affected by severe drought throughout history; in this lesson students explore this concept by analyzing environmental data to classify patterns and practice communicating their findings.
Students build an understanding of flooding in Colorado using multiple data sources in a jigsaw format.
Wildfires are occurring more frequently and increasing in size in the western US; in this lesson students will explore this concept by analyzing environmental data to find patterns and practice communicating their findings.
In this sub-unit, students will learn more about their community’s resilience plans, choose a specific topic to focus on, and develop a product to communicate the plan to their peers and/or their community.
The Community Resilience Expo is a culminating event for the HEART Force curriculum, where students will develop and present original ideas to increase resilience in their community.
Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!
Experiment with conductivity in metals, plastics and photoconductors. See why metals conduct and plastics don't, and why some materials conduct only when you shine a flashlight on them.

Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.
In this lesson, students create a compass and apply their reasoning about magnetism to how compasses work to help us navigate around the globe while utilizing the Earth’s magnetic field.
With your mouse, drag data points and their error bars, and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, cubic, or quartic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.
