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.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

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

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

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

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.
