In this activity, students create a scale model depicting the vertical distance from Earth’s surface to various features and objects, including Earth’s atmospheric layers, the Van Allen Radiation Belts, and geocentric satellites. Students also... (View More)

This collection of math problems is based on a weekly series of space and Earth science problems distributed to teachers during the 2013-2014 school year. The problems were intended for students looking for additional challenges in the math and... (View More)

This is an activity about scale. Participants will arrange imagery of Earth and many other space objects in order of their size from smallest to largest, their distance from Earth's surface, their temperature from coolest to hottest, and/or their... (View More)

The Cosmic Times Gallery Walk and Cosmic Times Jigsaw lessons serve as extensions to the Cosmic Times suite of curriculum support materials. They are intended to provide an introduction to Cosmic Times as a whole, giving students the larger picture... (View More)

Learners select from a variety of fruits to construct a scale model of the Moon, Earth, and Sun. After determining the correct sizes and distances for their models, they remove the Moon. They consider what it would be like if the nearby Moon were no... (View More)

This is a demonstration about the density of the planets. Learners will compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods. They will then dunk the "planets" in water to highlight the fact... (View More)

Learners will shrink the scale of the solar system to the size of their neighborhood and compare the relative sizes of scale models of the planets, two dwarf planets, and a comet as represented by fruits and other foods. This activity requires... (View More)
