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.
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
Infant Moon: Moon Mix!
Source Institutions
In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Exploring the Universe: Orbiting Objects
Source Institutions
“Exploring the Universe: Orbiting Objects” is a hands-on activity that invites visitors to experiment with different sized and weighted balls on a stretchy fabric gravity well.
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.
Particle Detection
Source Institutions
By tossing, collecting, and sorting beanbags, learners understand how the IBEX spacecraft uses its sensors to detect and map the locations of particle types in the interstellar boundary.
Make a Comet Model and Eat It!
Source Institutions
In this activity, learners build models of comets, using edible materials, to learn about comets' structure.
The Thousand-Yard Model
Source Institutions
This is a classic exercise for visualizing the scale of the Solar System.
