The Pull of the Planets
Source Institutions
In this activity, learners model the gravitational fields of planets on a flexible surface.
Dunking the Planets
Source Institutions
In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.
Build a Solar System
Source Institutions
In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei
Construction and Destruction
Source Institutions
In this three/four-day lesson, learners calculate perimeters and areas and draw the castle plan to scale.
Life Size: What's in a microbe?
Source Institutions
In this activity on page 3 of the PDF, learners visualize the relative size and structural differences between microbes that have the potential to cause disease.
Human-powered Orrery
Source Institutions
In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.
Plankton Feeding
Source Institutions
This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.
Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.
Slimy Cells
Source Institutions
In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.
Garden Poles
Source Institutions
In this activity, learners build large-scale structures and cantilevers in a series of "building out" challenges with garden poles and tape.
Cylinders and Scale
Source Institutions
In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.
Looking Back Through Time
Source Institutions
In this activity, learners create their own archaeological profiles.
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.
Our Solar System to Scale
Source Institutions
In this activity, learners plan and create a 24-foot long, two-dimensional model of our solar system, and compare and contrast the differences between planets and the sun.
The Size and Distance of the Planets
Source Institutions
In this activity, learners investigate the concepts of relative size and distance by creating a basic model of the solar system.
Atmosphere Composition Model
Source Institutions
In this activity, learners create a model using metric measuring tapes and atmosphere composition data.
Toilet Paper Solar System
Source Institutions
In this activity, learners build a scale model of the solar system using a roll of toilet paper.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
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.
Eclipse: How can the little Moon hide the giant Sun?
Source Institutions
In this activity, learners explore how distance can affect the way we perceive the size of an object.
