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

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

In this activity about scale, learners investigate the world of the very small by cutting a 28 centimeter strip of paper in half as many times as they can.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

In this activity, learners will plot the distribution of various oozes using information from sediment maps.
