This is an activity in which learners will find that they can detect differences in concentration better with their nose (smelling) than with their eyes (seeing). Our sense of smell allows us to...

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. This is a fun (and tasty!) way for...

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup. They learn that size can affect the way materials like...

In this activity, learners use their sense of smell to explore the world on the nanoscale. Learners discover that we can smell some things that are too small to see, and that a nanometer is a...

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales. Use...

In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see. The activity...

In this activity, learners explore materials through paper chromatography. This process highlights the properties of different pigments blended together in a marker by creating a colorful...
