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)

This is an activity about solar energy. Learners will first use computers to research and learn how solar panels convert sunlight into electricity. Next, they will calculate the surface area of solar panels board a satellite and their total power... (View More)

This is a set of three activities about how scientists study other worlds. Learners will explore and compare the features of Mars and Earth, discuss what the features suggest about the history of Mars, and create a model to help them understand how... (View More)

Audience: Informal education

This is an activity about how much atmospheric pressure is needed on Mars to maintain surface water and why it does not have surface water today. Learners will use a computer interactive to learn about Mars past and present before exploring the... (View More)

This is a lesson about landing site selection. Learners will work in teams to determine a landing site for their Mars Rover that best relates to their scientific question. They use technology skills to research Gale Crater through an online... (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)

Learners will record detailed observations of a simulated surface and core sample of Mars, analyze a simulated surface and core sample of Mars, compare and contrast an unknown foreign object with the surface and interior of Mars, and learn... (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 model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it... (View More)
