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

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

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

This activity introduces learners to the structure and properties of carbon nanotubes.

In this activity, learners investigate what happens when you build up static electricity on plastic balls.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.
