- Planets
Experiment: Make your own craters!
Let’s make our own craters in cocoa and flour to learn how these features form throughout the solar system — and why they’re different sizes.
- Physics
Experiment: Making music with bottles
In this study, we investigate how the volume of air inside a bottle affects the pitch of the musical notes it can create.
- Humans
Experiment: Why does the moon look larger on the horizon?
In this experiment, let’s investigate Emmert’s law, which may explain the full moon optical illusion.
- 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?
