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.
Flashy Fish
Source Institutions
Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.
Are you a Square or a Rectangle?
Source Institutions
In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.
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
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.
Race for Survival
Source Institutions
During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
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.
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.
Eat Like a Bird
Source Institutions
Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.
Fingerprints
Source Institutions
In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.
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.
