Why are Compact Fluorescent Bulbs More Efficient?
Source Institutions
In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.
Spaghetti Bridge
Source Institutions
Play with your food while learning about engineering! Build a spaghetti bridge, then test its strength by piling on the marshmallows, raw spaghetti, raw linguine and coins.
Does Sunscreen Protect My DNA?
Source Institutions
In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.
Submarine: Soda Cup Lander
Source Institutions
In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density.
Solar Powered Cooking
Source Institutions
In this activity, learners make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!
Water Filter
Source Institutions
In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
Cook Food Using the Sun
Source Institutions
Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.
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.
Fruity Electricity
Source Institutions
In this activity, Frankenstein's lab is running out of electricity! Learners use fruit to help Igor find a temporary source of energy to turn on a light.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Measuring Wind Speed
Source Institutions
In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.
DIY Pasta Rover
Source Institutions
In this activity, learners design and build a NASA rover using raw pasta and candy with a limited imaginary budget.
Critical Angle
Source Institutions
In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
NEWspaper: Make Your Own Paper
Source Institutions
Learners make their own paper using old newspaper. Learners can make their paper colorful by adding construction paper.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
Electric Switches
Source Institutions
In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.
Folding Matters
Source Institutions
In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.
Make Ziff's Carpenter's Square
Source Institutions
In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.
