Helicopter Twirl
Source Institutions
Learners cut and fold a paper helicopter from the template in this PDF. They practice twirling the helicopter and observe what happens as they modify their tries.
Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.
Instant Ice Cream
Source Institutions
In this activity, learners make instant ice cream without using a freezer.
Aluminum-Air Battery: Foiled again!
Source Institutions
Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.
Cool Hot Rod
Source Institutions
If you have access to a copper metal tube, this activity does a great job demonstrating what happens to matter when it's heated or cooled. This activity requires some lab equipment.
Get the Porridge Just Right
Source Institutions
Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.
Snow Day!
Source Institutions
In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate.
Hot Spot
Source Institutions
In this activity, learners explore the invisible infrared radiation from an electric heater.
Waterless Snow Globe
Source Institutions
In this activity, learners will investigate static electricity as they create waterless snow globes.
Mix and Match
Source Institutions
In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.
What Smart Metal!
Source Institutions
In this activity (pages 3-4), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
The Unpoppable Balloon
Source Institutions
In this activity, learners explore polymer structure and their ability to reform around objects by attempting to stab a wooden skewer through a balloon without popping it.
Cup Speaker
Source Institutions
Make your own speaker with a magnet, wire, and paper cup! If you have a radio with a headphone plug and an old pair of headphones, this is a great tinkering activity.
Falling Feather
Source Institutions
In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall
Bubble Cups
Source Institutions
In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.
Two Lenses in One
Source Institutions
In this activity about light, learners explore how water can refract light and change the way they see things.
DNA Detective
Source Institutions
This activity is about collecting and analyzing DNA as part of a criminal investigation.
Soaring Satellites
Source Institutions
Working in small teams, learners try to build a satellite that can float for at least five seconds in the marked area of a vertical wind tube.
Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
