Super Sounding Drum
Source Institutions
In this activity, learners construct drums out of everyday containers (like bowls or food containers) and shrink wrap. Learners use a hair dryer to affix and tighten the shrink wrap to the container.
Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.
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.
Exploring Shadows
Source Institutions
This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
Stereo Hanger
Source Institutions
In this activity, learners investigate sound wave science, in stereo! Learners construct a "stereo" out of a metal coat hanger and piece of string to explore sound vibrations.
Penny Cup Game
Source Institutions
In this optics activity, learners conduct an experiment to find out why two eyes are better than one!
Peripheral Vision
Source Institutions
In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.
Train Your Brain
Source Institutions
In this activity, learners play a trick on their own brain to see if the brain can learn to ignore distracting input. Colors and words are used to play the visual trick, known as a Stroop Test.
What's the Buzz?
Source Institutions
In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.
Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.
Design a Flavor: Experiment to Make Your Own Ice Cream Flavor!
Source Institutions
In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.
Reaction Time
Source Institutions
In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.
Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.
Phenakistascope
Source Institutions
In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.
Kaleid-o-mania
Source Institutions
In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.
Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.
Magic Disc
Source Institutions
In this activity, learners create an optical illusion by spinning two attached cups. A round ball seems to magically appear when the cups spin.
