We’ve improved the Capacitor Lab sim with a new “Multiple Capacitors” tab, where you can explore series and parallel relationships.
Try the new Build-a-Molecule sim. Starting from atoms, see how many molecules you can build. Collect your molecules and see them in 3D! You’ll learn the differences between atoms and molecules, and how to construct them.
Are all atoms of a given element the same? How can you tell one isotope from another? Learn about isotopes, and about how to calculate the average atomic mass of an element.
Explore bending of light between two mediums with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
After more student testing, we’ve improved the Gravity and Orbits sim as well as fixed some bugs. (If you find more, please let us know!) Grab the planet and change the planet-star distance or the planet’s velocity, and explore how that impacts the orbit.
Try our new Balancing Chemical Equations sim.
How do you know if a chemical equation is balanced? What can you change to balance an equation? Play a game to test your ideas!
After more student testing, we’ve improved the Buoyancy sim. And, don’t forget that you can lift the blocks out of the water by using the underwater scale.
Watch different types of molecules form a solid, liquid or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.
Insert channels in a membrane and see what happens. See how different types of channels allow particles to move through the membrane.
Wow! We are so excited to announce that we now have over 100 sims at our website. And, look for more to come.
