All Stories by Science Buddies
- Physics
Experiment: Measure the speed of light with a laser
Grab a laser pointer and some Jell-O, because today we’re measuring the speed of light.
- Chemistry
Experiment: How to make the boldest, brightest tie-dye!
Clothes are made from a variety of fibers, from natural to synthetic ones. Let’s explore how different fibers react with dyes.
- Physics
Experiment: Make your own cents-able battery
Make your own ‘voltaic pile’ with pennies and nickels, and find out how many coins will make the most electricity!
- Earth
Experiment: Can plants stop soil erosion?
Soil erosion washes pollutants into streams and rivers — but plants may help limit that.
- Animals
Experiment: Are we there yet? Test how migratory birds navigate
In this experiment, use real data to figure out how migratory birds navigate from their breeding grounds to their wintering grounds.
- Physics
Experiment: Where does a bouncing basketball’s energy go?
Let’s explore whether energy loss to heat could explain why a basketball doesn’t bounce back to its original height.
- Physics
Experiment: How well do different materials create static electricity?
Why are some materials more susceptible to static cling than others? Investigate by making your own electroscope.
- Chemistry
Experiment: Kimchi chemistry
In this cooking and food science project, we make kimchi from scratch and investigate changes in pH and glucose as it ferments.
- Earth
Take candy core samples with this science activity
Act like a geologist as you drill ‘core samples’ from candy bars using a straw. Can you identify the type of candy bar just from a sample?
- Space
Experiment: A puzzling parallax helps stargazers
In this project, we explore how perspective, or parallax, can be used to measure the distances to objects such as stars.
- Chemistry
Experiment: Test the effect of temperature on reaction time
Alka-Seltzer tablets fizzle furiously when dropped into water. Can you make Alka-Seltzer fizz faster or more loudly by changing the water’s temperature?
- Chemistry
Experiment: Keep your candy cool with the power of evaporation!
In this science project, use the energy produced when water evaporates to cool down chocolate-covered candy so it doesn't melt.
