Metal Reactions
Source Institutions
This is written as a static display, but can easily be adapted to a hands-on experiment for learners to conduct.
Exploring Materials: Nano Gold
Source Institutions
In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
Surface Area
Source Institutions
In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
The Power of Words
Source Institutions
This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.
Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
Luminol Test
Source Institutions
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Cartesian Diver
Source Institutions
In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.
Amazing Marshmallows
Source Institutions
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.
The Electric Squeeze
Source Institutions
In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.
Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.
Waterproof Hanky
Source Institutions
In this physics demonstration, learners will be surprised when a handkerchief holds water in an upside-down glass.
Inkjet Printer
Source Institutions
In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.
Forgotten Genius
Source Institutions
This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p
Transformation of E. coli Using Green Fluorescent Protein
Source Institutions
In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.
Lava Lamps
Source Institutions
Learners observe working lava lamps to understand how they work (included in PDF link).
Electrolysis
Source Institutions
Learners observe two joined glass tubes containing a conductive salt solution. Electrodes are passing an electric current through the water.
Musical Sculpting Machine: Squeeze Play-Doh to Make Music
Source Institutions
Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.
Fruit Xylophone: Fruit Salad Instrument of the Future!
Source Institutions
This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.
Egg-Citing Physics
Source Institutions
In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.
