Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
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.
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
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.
Spinning Illusions
Source Institutions
In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Bubble Sculpting
Source Institutions
In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.
Measurement: Bubble Mania
Source Institutions
In this math lesson, learners practice measurement skills as they examine a soap bubble print. Learners follow a recipe to make a soap bubble solution.
Exploring Bouncing Balls
Source Institutions
Learners explore the physical properties of a variety of balls and how they bounce.
Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.
Topological Puzzles
Source Institutions
In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.
Two-String Yo-Yo
Source Institutions
Learners build a yo-yo using a piece of wood, PVC pipe, and string. In doing so, learners explore the force of gravity and angular momentum.
Hovercraft
Source Institutions
In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.
