Gravity And Orbits
Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....
Physics Classroom
Spectrum
Scholars relate each of the colors in the spectrum, except indigo, by comparing their frequencies, wavelengths, and energy levels. Then, they compare each section of the electromagnetic spectrum when considering the same three variables.

Stow Lake
Does the depth of a pond matter to the waves created when rain is falling? Many people assume the answer is no, but interestingly, it does matter. Pupils explore this concept and other variables related to wave behavior through a...
Physics Classroom
Case Studies: Impulse and Force
Why are gym walls padded and cars required to have air bags? Scholars observe two similar situations, such as those listed above, with only one variable altered. They identify the different variable and determine how the variation...
