Lagging Sound
Source Institutions
In this group activity, learners see and hear the speed of sound. A learner designated the "gonger" hits a gong, once every second, as the rest of the group watches and listens from a distance.
Big Wave
Source Institutions
This is an activity about waves. Using marbles, paper clips and rubber bands, learners explore how waves behave.
Waterless Snow Globe
Source Institutions
In this activity, learners will investigate static electricity as they create waterless snow globes.
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.
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.
The Game of Life: Stem Cell Edition
Source Institutions
In this activity, learners play a game that models what happens as stem cells differentiate into different cell types.
Shell Shifts
Source Institutions
Ocean acidification is a big issue due to the amount of carbon dioxide humans release. CO2 in the atmosphere is absorbed into the ocean thus changing its acidity.
Spaghetti Bridge
Source Institutions
Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.
Submarine: Soda Cup Lander
Source Institutions
In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.
Homemade Snow
Source Institutions
In this sensory activity, learners enjoy the fun of a snow day any season of the year.
Floating Dry Erase Creations
Source Institutions
In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.
Fruity Electricity
Source Institutions
In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.
Heat Speeds Up Reactions
Source Institutions
In this activity, learners investigate the effect of heat on a reaction.
Oily Ice
Source Institutions
In this activity, learners experiment with the density of ice, water, and oil. Learners will discover that the density of a liquid determines whether it will float above or sink below another liquid.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
DNA Extraction
Source Institutions
Learners use a simple process to extract DNA from strawberries.
Shake It Up!
Source Institutions
Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.
Iron for Breakfast
Source Institutions
Did you know that some breakfast cereals are fortified with ferric phosphate, while others contain tiny pieces of reduced iron?
Light Combinations
Source Institutions
In this activity about magnetism (page 17 of the pdf), learners experiment with magnets, exploring the concept of diamagnetic materials by seeing how a grape reacts to a magnetic field.
