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.
Launch It
Add to list DetailsIn this design challenge activity, learners use a balloon and other simple materials to design an air-powered rocket that can hit a distant target.
Basking Basics
Source Institutions
In this activity, learners will explore reptile biology by taking temperature readings in various places and comparing them.
Sandy Samples
Source Institutions
In this collecting/comparing activity, learners work with samples of sand from different places like a lakefront, river, or ocean beach.
Gumdrop Dome
Source Institutions
In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.
Kool Colors
Source Institutions
Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.
Spaghetti Bridge
Source Institutions
In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.
Evaporation
Source Institutions
This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.
Comparing the Density of Different Liquids
Source Institutions
Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.
Animal House
Source Institutions
The goal of this activity is to design, build and test a house or toy for an animal.
Hidden Color Chemistry
Source Institutions
In this activity, learners will discover what colors are in different markers, and may be surprised at the results.
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.
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.
What Gives?
Source Institutions
In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.
Paper Towel Strength
Source Institutions
In this activity, learners will test the strength of different brands of paper towels.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.
Make a Speaker: A Coil, a Magnet, and Thou
Source Institutions
Make your own simple speaker so you can listen to your favorite radio station. Just wind a coil, attach it to a piece of cardboard or Styrofoam, hold a magnet nearby, and listen.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
