This Exploratorium activity explores size and scale. Through four levels of screen sizes, learners can sort out objects of different sizes.

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

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).

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 discover that a material can act differently when it's nanometer-sized.

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 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 build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

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.

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 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.

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

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

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

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

In this activity, learners explore how the application of nano-sized "whiskers" can protect clothing from stains.

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

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
