In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

In this activity, learners place cards featuring biological structures in order by their relative size from largest to smallest.

In this activity, learners explore a scale by comparing objects, which look similar but have different weights. Learners predict and then measure the weights of various objects using a scale.

In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.

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

In this activity, learners explore their eye pupils and how they change.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this physics activity, learners explore how sound is created by vibrations.

In this activity, learners will construct a device to blow bubbles. By adding corn syrup to the bubble solution, we can increase the surface tension of the bubbles--and their size.

In this activity, young learners will describe objects by their properties and sort by color, weight and texture. This activity uses household items and toys for materials.

In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

In this activity, learners engineer a flying glider using paper hoops and a drinking straw.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity, learners compare different types of salt crystals under a magnifying glass.

In this activity, learners investigate static electricity using everyday objects at four different stations.

This is an activity about circular motion. Learners will explore the laws of motion and force by observing circular motion.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

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