Electrical Fleas
Source Institutions
In this activity about electricity, learners explore how static electricity can make electric "fleas" jump up and down. Learners use a piece of wool cloth or fur to charge a sheet of acrylic plastic.
Make Your Own Sculpture Dough
Source Institutions
In this activity on page 7 of the PDF, learners follow a recipe to make a dough similar to the clay artists use to make sculptures.
CD Spinner
Source Institutions
In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.
A Funny Taste
Source Institutions
In this activity, learners explore the different salinities of various sources of water by taste-testing.
Newspaper Collage
Source Institutions
In this activity on page 3 of the PDF, learners create a collage by using vinegar to transfer color pictures from a newspaper onto a piece of white paper.
Rollback
Source Institutions
In this physics activity (page 10 of the PDF), learners will make a can that will roll back after it has been rolled away to observe the interactions of kinetic and potential energy.
Art with Salt and Ice
Source Institutions
This open-ended art project allows learners to create their own colorful ice sculpture by using rock salt and food coloring on a solid block of ice.
How Can Gravity Make Something Go Up?
Source Institutions
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.
Super Spinner
Source Institutions
In this activity (page 1 of PDF under SciGirls Activity: Pet Handedness), learners will construct a simple spinning top out of a circle of construction paper, a film canister lid, and a bamboo skewer.
Chew that Gum
Source Institutions
In this quick activity (page 1 of PDF under SciGirls Activity: Exercise and Memory), learners will investigate what happens to bubble gum when it is chewed for 5-10 minutes.
Bubble Tray
Source Institutions
In this activity, learners use simple materials to create giant bubbles.
Descartes' Diver
Source Institutions
In this activity, learners explore how changes in fluid pressure affect the buoyancy of a Cartesian diver inside a plastic soda bottle.
Exploring How Liquids Behave
Source Institutions
Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.
Exploring Liquids
Source Institutions
Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.
Cylindrical Mirror
Source Institutions
In this activity, learners create a cylindrical mirror to see themselves as others see them.
Iridescent Art
Source Institutions
This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.
Water Sphere Lens
Source Institutions
In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.
Eddy Currents
Source Institutions
In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.
Real Glass Xylophone
Source Institutions
In this activity, learners create a xylophone by filling glasses with different amounts of water and tapping them with a metal spoon.
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.
