Play with resistors, light bulbs, wires, switches, a battery, voltmeters, and ammeters in this interactive circuit simulation. Place elements on the grid and watch as electrons move and bulbs glow. This is a “sandbox” simulation where you can add and remove circuit elements however you like. Simulate parallel, series, or complex circuits with ease, and watch as the currents and voltage values instantly change.

Astronomical Images in Different Wavelengths

# data[].attributes.body
Explore astronomical objects shown at different wavelengths of electromagnetic radiation. Students can use the images as evidence for how various wavelengths provide different information about an object’s structure, composition, temperature, and other characteristics.

Change the location of the object and use the ray diagrams to determine the location of the image in this interactive simulation of a lens and mirror optics bench. You can toggle between a lens and a mirror and turn individual rays on or off. Both converging and diverging lenses and mirrors are included in this simulation.
