Lava Lamps
Source Institutions
Learners observe working lava lamps to understand how they work (included in PDF link).
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.
Dark Adaptation
Source Institutions
In this activity (6th on the page), learners investigate how photoreceptors in the eye (rods and cones) "adapt" to low light conditions.
Density Stacker
Source Institutions
In this physics activity (page 8 of the PDF), learners will explore the property of density.
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.
Beam Me Up!
Source Institutions
This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.
Checking For Starch
Source Institutions
In this chemistry activity (page 3 of the PDF), learners will observe a chemical change, specifically what happens to iodine when it is applied to ripe and unripe apples.
How Loud is Too Loud
Source Institutions
In this activity (described on pages 39-42 of PDF), learners make a paper wheel (on pages 57-60 of PDF) that shows them the relative loudness of different sounds.
Homemade Snow
Source Institutions
In this sensory activity, learners enjoy the fun of a snow day any season of the year.
Oil Slick
Source Institutions
Can you think of ways to collect and dispose of spilled oil without causing further harm to the environment?
Floating Dry Erase Creations
Source Institutions
In this activity, learners will create a drawing with dry erase markers and watch it come to life. Learners will explore chemistry, art and storytelling through this activity.
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.
Electric Highway
Source Institutions
In this design challenge activity, learners design and build a circuit: an "electric highway" that connects a battery and buzzer at least three feet apart using four types of materials.
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.
Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.
Bend It, Break It
Source Institutions
In this activity (on pages 25-32 of PDF), learners make models of the inner ear out of pipe cleaners.
Colors, Colors?
Source Institutions
In this activity related to the famous "Stroop Effect," learners explore how words influence what we see and how the brain handles "mixed messages." Learners read colored words and are asked to say th
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.
The Blind Spot
Source Institutions
In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.
