Welcome to our March 2015 Issue of our CoolStuff Newsletter. This month, we are featuring a simple, safe and Cool device called an Energy Stick. Physics teacher James Lincoln demonstrates several experiments that help students understand the principles of electric current and light. James has authored many of our past CoolStuff Newsletters, and teachers [...]

10 thermal conductivity demos for less than $12
Watch Physics Teacher James Lincoln use the simple, inexpensive Liquid Crystal Sheet to visually demonstrate:
-the temperatures of varying light sources
-how styrofoam insulation works
-the wavelength of a microwave
-plus much more!

Galileo claimed that all objects fall toward Earth with the same acceleration. Modern measurements indicate that this acceleration is about 9.8m/s2
. Using the G-Ball by Arbor Scientific, you can measure this value and compare the acceleration of other objects with different masses and in different states of motion.
