Using a plastic tray filled with sand to represent a planetary surface, learners simulate the effects of wind, water, and impacts. They will compare the surface effects they create with actual images of planetary surfaces- and determine the causes... (View More) of the features in the images. This activity was designed to be used in a library program. (View Less)

Students "observe" an imaginary new planet in our galaxy from the relative distances of a ground-based telescope, the Hubble Telescope, and a fly-by mission. After recording their observations and discussing the differences, they compare their... (View More) observations to actual images of Pluto taken from the New Horizons spacecraft during its July 2015 fly-by. (View Less)

Learners create scale models of Earth, the moon, and Mars out of playdough. Based on the size of the models, they must determine the relative distance between them and then display them at that scale. This activity was designed for use in a library... (View More) program. (View Less)

In this activity, children use common craft materials and ultraviolet (UV)-sensitive beads to construct a person (or dog or imaginary creature). They use sunscreen, foil, paper, and more to test materials that might protect UV Kid from being exposed... (View More) to too much UV radiation. Includes background for facilitators. This activity is part of the "Explore!" series of activities designed to engage children in space and planetary science in libraries and informal learning environments. (View Less)

Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different... (View More) frequencies/wavelengths of the electromagnetic spectrum and matter as they investigate the different ways scientists gather and understand remote sensing data, using Dawn instruments as examples. This module is organized around a learning cycle, engaging students through several experiences to activate students' prior knowledge and assess conceptual understanding, informing next steps.

This paper model shows the orbit of Comet ISON (late 2013) with respect to the innermost planets of the solar system. After reading background information about comets - how they form and where they come from - students cut out and tape together the... (View More) pieces of the model provided to show its orbital pathway (a single page of parts that can be assembled using just scissors and adhesive). Links are provided to related classroom activities and additional resources. (View Less)

Learners color images of the latest scientific data depicting the Moon's formation to create their own comic strips of our Moon's birth. The children use different-colored balls of Play-Doh® to model the impact between Earth and a small planet 4.5... (View More) billion years ago. "Debris" from both "planets" is rolled into a small ball to model how our Moon formed through the process of accretion of smaller particles. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

Learners model how Earth's tilt creates the seasons. They use their bodies to review the Earth's daily motions before investigating the reason for Earth's seasons in this kinesthetic exploration. The motion of the Earth about its axis (rotation) and... (View More) in orbit around the Sun (revolution) is related to the appearance of the sky over the course of the day and year. Next they model that if the Earth's tilt was not stabilized by Moon, Earth's axis would slowly wobble between straight up (0° tilt) to nearly on its side (80° tilt). The resulting seasonal extremes would be unfavorable for life. Note that this activity is appropriate for children who are able to explore the geometry of Sun-Earth-Moon relationships in three dimensions. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

This module focuses on ultraviolet radiation on Earth and in space and how it affects life. Learners will construct their own "martian" using craft materials and UV beads. They will explore how UV radiation from the Sun can affect living things,... (View More) comparing conditions on Earth and Mars, and then discuss ways in which organisms may protect themselves from UV radiation. They will then take part in a Mars Creature Challenge, where they will change their creature to help it survive harsh UV conditions — like on Mars. They will then test their Mars creatures by subjecting them to different environmental conditions to see how well they "survive" in a martian environment. This investigation will explore shelter and protection as one of life’s requirements and how Earth’s atmosphere protects life from harmful UV radiation. It also includes specific tips for effectively engaging girls in STEM. This is activity 5 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)
