Chromatography
Source Institutions
In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.
Canine House of Cards
Source Institutions
This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.
Floating Paper Clip
Source Institutions
In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.
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.
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.
Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.
Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.
All Wound Up
Source Institutions
In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.
Float My Boat
Source Institutions
In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?
Action Figure
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.
Roving on the Moon
Add to list DetailsIn this design challenge activity, learners build a rubber band-powered rover that can scramble across the room.
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.
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.
Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.
Under Pressure
Source Institutions
In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.
Mirror Messages
Source Institutions
In this activity, learners use mirrors to write secret messages to a friend. Use this activity to explore letters, optics, and/or symmetry.
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.
Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.
Fingerprints
Source Institutions
In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.
