In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
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.
Human-powered Orrery

Light on Other Planets
Source Institutions
In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe
Introduction to Ocean Zones
Source Institutions
In this activity, learners will create a diagram of the ocean zones and determine what organisms live in each zone.
Solar System in My Neighborhood
Source Institutions
In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
Dinosaur Flesh and Bones
Source Institutions

Jump to Jupiter
Source Institutions
In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.
Stuck on You: Adhesion
Source Institutions
Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others.
Where in the World is the Terra Cotta Army?
Source Institutions
In this activity, learners find Xi'an, the archaeological area in China where the Terra Cotta Army was discovered, on a map or globe and look more closely at the relationship of the warrior site to ot
