Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Digit's Cyber-Dough
Source Institutions
In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.
Two Washers
Source Institutions
In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Pinball Wizard
Source Institutions
In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.
Make Maracas
Source Institutions
Make a rattle-like musical instrument! Shake it, hit it, spin it any way you want to!
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.
Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.
Pop Bottle Whirligig
Source Institutions
Learn about friction and kinetic energy with this cool spinning toy.
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.
Ramp Racers
Source Institutions
In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Achieving Orbit
Source Institutions
In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat
Up Periscope!
Source Institutions
This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.
Bobbing Eyeballs
Source Institutions
In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.
Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.
Some Sums
Source Institutions
In this math game, learners solve a mind-twisting puzzle using dominoes. Use this activity to help learners practice counting, adding, and solving problems.
Swinging Yo-Yo
Source Institutions
Learners build a pendulum from a yo-yo, and then design their own experiment to determine what affects the pendulum's period of swing.
Lava Lamp
Source Institutions
In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.
