In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

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).
