In this activity, learners play a card game that explores the relative sizes of various objects. Learners compete to organize their hand of cards into lists of objects from largest to smallest.

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 investigate how inkjet printers produce tiny, precise drops of ink.

Learners make their own simple slide rules out of paper and learn how they work.

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).

Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.
