In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Learners combine hydrogen peroxide with three different forms of potato: raw chunks, ground chunks, and boiled chunks.

In this chemistry meets cooking activity, learners make carbonated, vanilla ice cream using dry ice and denatured ethanol, which are both inexpensive and accessible.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

This magic trick is based on how computers detect and correct data errors.

Break open that used musical toy and squish some Play-Doh over the circuit boards, and you will hear some weird and distorted sounds the manufacturer never intended!

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

Learners use a candle to investigate the products of combustion. When a glass rod is held over a lit candle, the candle flame deposits carbon on the rod.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

In this activity, learners perform a simulated blood test procedure.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this activity, learners discover that atoms and ions of different metals will change places.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

This paper describes a working-model demonstration of Ernest Rutherford's 1911 experiment about the nature of atoms.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.
