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. 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. An introduction to the Ice Balloons activity, in which learners explore globes of frozen water and learn how to ask and then answer 'investigable' questions. A detailed demonstration of how to do the Ice Balloons activity, including a discussion of materials needed and strategies for getting learners to ask and then investigate questions about what they are seeing. The science and pedagogy behind this activity, including a discussion of concepts such as density, temperature, thermal conductivity, center of mass, freezing point depression, heat capacity, and the characteristics of the states of water, water vapor, and ice. Also describes strategies for observing, asking questions, and then choosing a question to investigate further. In this activity, you'll explore a frozen water balloon to learn how to ask investigable questions and how to use everyday objects to do experiments to answer those questions.
