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

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

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.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

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 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.

In this activity, learners complete a series of drawing activities to explore scale and powers of 10. Learners first trace each other on 1-meter-square pieces of paper.

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

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

In this classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.

In this activity/demo, learners examine a synthetic gecko tape with micron sized hairs that mimics the behavior of the gecko foot.
