In this activity, learners describe an object they can’t see. After someone picks outs a few mystery objects and places them in a pillowcase, learners will investigate using only their hands.

In this activity on page 1 of the PDF, learners compare the relative sizes of biological objects (like DNA and bacteria) that can't be seen by the naked eye.

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 explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity, learners will create a magnifying glass called a waterscope, using water and household items, to examine various objects.

This simple activity uses paper and scissors to convey two key concepts to learners: the nanoscale is very small and working on the nanoscale requires special tools.

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

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?
