In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies.

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

Using information from the My Place in Space lithograph, learners write and/or draw a postcard to friends and family as if they had gone beyond the interstellar boundary of our Solar System, into the
