Proportionality: The X-Plane Generation
Source Institutions
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.
What is a Nanometer?
Source Institutions
This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.
Shrinking Cups
Source Institutions
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.

Cutting it Down to Nano
Source Institutions
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.
Comparing Sizes of Microorganisms
Source Institutions
In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete
