How would a pendulum work on the moon or Jupiter? To answer that question scholars control up to two pendulums including their location, length, mass, and amplitude. Added controls include changing the friction and strength of gravity....

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

Three main factors determine the wave height experienced in the ocean. Scholars use a virtual simulator to alter wind speed, fetch, and duration. Each combination creates a unique wave measured in significant height.

Talk about a cool tool! Convert between units with the click of a mouse using a handy online resource. Enter the starting measurement and units for quantities such as torque, speed, and inertia, then sit back and relax while the computer...

How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength...
