News: Build Your Own Oscillating Wave Machine
Transverse wave motion is the beautiful rippling effect that occurs when a moving wave causes oscillations that travel perpendicular to the direction of energy transferred. (For example, via Wikipedia: "If a transverse wave is moving in the positive x-direction, its oscillations are in up and down directions that lie in the y–z plane.")

How To: Explore Density, Viscosity & Miscibility with a Colorful Layered Liquid Science Experiment
Ever wonder why Jupiter has those colored bands across its surface? Jupiter's enormous mass is made from an array of different liquids, and those fluids do not play well together because of their different makeup. All of the hydrogen- and helium-based fluids are thought not to be miscible, which means that they aren't homogeneous in nature, resulting in strikingly beautiful bands across the planet's surface. But what about viscosity and how that correlates to the development of planets? What ...
How To: Use a protractor to measure the height of any object
In this video, we learn how to use a protractor to measure the height of any object. First, attach a level to the protractor, followed by a straw at the 45 degree angle. Next, walk back form the object while looking through the straw. Keep walking back until you spot the top of the object through the straw, then measure to the base of the object. After this, you will have an isosceles triangle that has two equal sides. Use these sides to help find what the size of the object is. After this, a...
