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 about gravity (page 6 of the PDF), learners will come to understand how all objects will fall at the same rate, but that air will slow things down.

This demonstration activity models how Venus appears from Earth.

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

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

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.

In this activity, learners explore how distance can affect the way we perceive the size of an object.
