In this week's spotlight: a pair of projects that put statistics in the palm of your hands. In these hands-on math projects and activities, students investigate to find out how often each color of M&M appears in a bag or group of bags. Have a guess as to which color appears most often? Put your guess to the test! What is the likelihood of pulling a yellow M&M from a brand new bag? After this activity, your student will be able to give you the odds—with some statistics to back them up!…

Even during a global pandemic like COVID-19, there are differences in how the epidemic unfolds within communities. Some communities see early, large waves of infected individuals, while others see smaller numbers of infections over a longer period of time, and others may not appear to have an epidemic at all. Could R₀ (pronounced R naught), account for some of this variation?
R₀, the basic reproduction number of a disease, quantifies how many people, on average, an infected…

A solution consists of a solute dissolved in a solvent. A solution is saturated when no additional solute will dissolve in it. Can a saturated solution of sodium chloride dissolve any Epsom salts? Can a saturated solution of Epsom salts dissolve any sodium chloride? How does solubility vary with temperature? How does solubility vary with the surface area of the solute? Design experiments to find out! (Gardner, 1999, 16-17, Stretton, 2004)

If you stare at a waterfall, or look at passing scenery from the window of a moving train, you will have a strange sensation when you turn your gaze to something stationary. You can investigate these types of motion after-effects
with simple equipment described by the Exploratorium.
How long does it take to induce the effect? How long does the effect last? Can the after-effect be canceled by viewing motion in the opposite direction? (Staff, date unknown)

Do you love to listen to your MP3 player while you're exercising, or listen to songs on the Internet? The relatively recent development of MP3 technology has made it possible to take a stack of CD's and store them on a device no bigger than a deck of cards. How does the MP3 format squeeze all those CD's down so well, and can it go too far? Try this music science fair project to find out!

In this week's spotlight: a pair of projects that bring the science behind Egyptian mummification into the kitchen or classroom. In these hands-on human biology projects and activities, students (and families!) simulate the process of mummification with a hot dog and baking soda. What does a mummified hot dog look like after seven days? After fourteen? Better yet, how does it smell! Experiment to find out what's really going on when something is mummified.
Minding your Mummies: The…

In this week's spotlight: a music-themed science activity that helps families explore the relationship between the sound an instrument like a clarinet makes and the length of the air column. When a sound wave travels down a longer or shorter distance, how does what we hear change? In this activity, students use glass bottles filled with differing amounts of liquid to experiment. With some careful listening and trial and error, you might be able to play a song by blowing on the bottles in a…

In this week's spotlight: a music-themed family science experiment and science fair project. With a set of ordinary drinking straws, you can create a group straw "oboes." Can you play them? Sure! By blowing air through them, similar to the way you play a reed instrument, you can produce musical notes. At the end of the activity, you should have a set of straws, each of which will play a different note on a musical scale. What is the secret to changing the note each one plays? In this music…
