TI staff educator Eric Muller shows me how to carbonate my tongue. Blech!
A detailed demonstration of how to do the Color Chromatography activity, which lets you see the colors hidden in black ink. Includes a discussion of materials needed. An introduction to how to make your own simple speaker, which transmits sound from a radio or MP3 player and demonstrates the principles of electromagnetism and vibration. A detailed demonstration of how to make a cup speaker, including a discussion of materials needed. The science behind the Cup Speaker activity, including how electromagnets work, and how in this activity the magnet pushes the bottom of a cup back and forth, vibrating the air and creating sound. TI teacher coach Jennifer Paillet explains how to fit in more labs, and get students thinking creatively by using take-home labs. Exhibit developer Erik Thogersen backs away from the Giant Mirror. Watch his image change as he passes through the focal point, then continues on past the center of curvature. At the Giant Mirror, Senior Staff Scientist Paul Doherty demonstrates a simple way of locating a real image—an image that floats in space in front of the mirror. An introduction to an activity that lets you discover the secret colors hidden in black ink. With a paper towel, a black marker, and a cup of water, create a rainbow of colors while exploring capillary action and chromatography. Explore the science behind this activity, including capillary action (how the water moves up the paper) and chromatography, or how different elements of the ink are carried along at different rates, allowing you to see that black ink is actually made up of many different colors.
