Iron in Cereal: Find iron in your food!
Source Institutions
Learners investigate an iron-fortified cereal by stirring it with a strong magnet. They discover that metallic iron is present in some cereals.
Cup Draw (Low Tech)
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves.
Cup Draw
Source Institutions
In this activity, learners construct drawing machines using a cup, some markers, and a cricket to control the movement. A programmed LEGO RCX or Cricket is required for this high-tech version.
Sizing Up Temperature
Source Institutions
In this activity, learners explore Charles' Law in a syringe.
Spicy Indicator: Use turmeric to test for bases in your home
Source Institutions
This activity uses turmeric, a common spice in curry, as an indicator for acidity and basicity. Turmeric is yellow in acid and neutral substances, but turns bright red with bases.
Depth Perception
Source Institutions
In this easy demonstration (3rd on the page), learners explore depth perception by conducting a test with two pencils.
Supernova Star Maps
Source Institutions
This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.
Chromatography
Source Institutions
In this activity (page 3 of the PDF), learners will observe a physical change.
How Thick is Your Hair?
Source Institutions
In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.
Demonstrating An Epidemic
Source Institutions
This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi
Shake and Match
Source Institutions
In this activity, learners create a hearing based memory game that they can share with friends.
Drag: Parachute from the Stratosphere
Source Institutions
This is an online game recreating the longest ever (at that point in time) freefall jump by Air Force Captain Joe Kittinger.
Spool Racer
Source Institutions
In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.
Self-Assembling Dessert Toppings
Source Institutions
This is an activity (located on page 3 of the PDF under Self-Assembly Activity) about self-assembly, the ability of molecules to assemble themselves according to certain rules.
Glow in the Dark
Source Institutions
Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
Two Ears are Better Than One: Sound Localization
Source Institutions
This activity (9th activity on the page) about hearing demonstrates to learners the importance of having two ears.
Rubber Band Car
Source Institutions
In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.
Solubility Test
Source Institutions
In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.
Butter Up
Source Institutions
In this activity, learners will discover how to make butter from scratch. One optional tips includes adding marbles to speed up the process.
Shrinking Spot
Source Institutions
In this activity, learners control the (apparent) size of a hole with their brain.
