Soap Bubble Shapes
Source Institutions
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Rocket Launchers
Source Institutions
In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.
Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.
Wrap It Up!
Source Institutions
In this Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.
Shaving Cream Marbling
Source Institutions
In this activity, learners will create beautiful greeting cards by marbling with shaving cream and food dye. They will explore the chemistry behind the art of marbling.
Magnets are Marvelous
Source Institutions
In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.
Float or Sink?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
COSI's Bubble Recipe
Source Institutions
Everybody loves bubbles, and this is the best bubble recipe ever!
Zip Line Zoo
Source Institutions
In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.
Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.
Silver Crystals
Source Institutions
This is written as a static display, but can easily become a hands-on experiment for learners.
Kosher Dill Current: Make Your Own Battery!
Source Institutions
This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.
Buoyancy Bulls-Eye
Source Institutions
In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ
Strange Attractor: Observe Chaotic Motion
Source Institutions
In this activity, learners can observe chaotic motion. A magnet tied to a piece of string makes a pendulum, which swings over three sets of fixed magnets.
Cook with a Solar Oven
Source Institutions
In this activity, learners make their own solar oven to bake s'mores and learn about how solar energy is absorbed on Earth.
Pulleys
Source Institutions
In this physics activity, learners experiment with pulleys and find that they can decrease the effort needed when using a pulley to lift or move different loads.
Sink or Float?
Source Institutions
In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.
Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.
Push Me a Grape
Source Institutions
In this physics activity, learners experiment with the attractive and repulsive power of magnets.
