In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners create a "Jam Jar Jet" based on Francois Reynst's discovery of a pulsejet engine, which uses one opening for both air intake and exhaust.

In this activity, learners use a flexible magnet as a model for a scanning probe microscope (SPM). They learn that SPMs are an example of a special tool that scientists use to work on the nanoscale.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, learners use chemistry to “self-assemble” gummy shapes. Learners discover that self-assembly is a process by which molecules and cells form themselves into functional structures.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

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.

In this activity, learners are challenged to design and build a miniature tree house in a potted plant. This activity uses engineering concepts to encourage creativity.

The Let's Do Chemistry "Build a Battery" activity lets participants learn how batteries work and how materials behave, change, and interact by building their own simple battery out of metal and felt w

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 play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

This is a hands-on activity exploring how nanoscale particles are used in mineral sunblocks to increase their transparency.

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

In this activity (on page 14 of PDF), learners use a pan full of flour and some rocks to create a moonscape.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?
