Circuit Game
Source Institutions
In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.
Carousel Pump
Source Institutions
In this activity, learners build a carousel toy that spins when pushed down.
Where Will It Go?
Source Institutions
In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.
Magnetic Spinner & Compass
Source Institutions
Learners use shop tools and various materials to construct a magnetic spinner and a compass.
Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Ball Bounce Experiment
Source Institutions
In this activity, learners investigate the properties of different types of balls.
How Can Gravity Make Something Go Up?
Source Institutions
In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.
Electric Paddle Boat
Source Institutions
In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.
Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.
Sled Kite
Source Institutions
In this activity, learners build a sled kite that models a type of airfoil called a parawing.
What Shape Is It?
Source Institutions
In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.
Bouncing Balloons
Source Institutions
In this sports-themed engineering activity, learners create super bouncy balls out of balloons. Learners brainstorm, test their designs, and share results.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Parabola Basketball
Source Institutions
In this activity, learners build mini-basketball courts and explore the laws of physics. Learners discover that everything you throw or shoot on earth travels in a parabola.
Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Get-Moving Game
Source Institutions
In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
Kaleidoscope
Source Institutions
In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.
Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.
