This series of investigative activities for Cadette Girl Scouts begins with an overview of our inner solar system, emphasizes the planetary histories of Mars, Earth and Venus, then concludes with evidence for the greenhouse effect on Earth. The... (View More) activities introduce and reflect the scientific goals of NASA's Mars Atmosphere and Volatile Evolution Mission (MAVEN), which reached Mars on September 21, 2014, and began its study of the Martian atmosphere. Cadettes will simultaneously learn about new technologies and gain new knowledge as they explore career pathways and develop potential service projects linked to the Cadette leadership journey.

Microscopic meteorites routinely reach Earth's surface. While challenging to find and identify, this activity provides techniques for searching for them in the local environment.

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)

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)

Learners model how the Moon's volcanic period reshaped its earlier features. The children consider that the broad, shallow impact basins contained cracks through which magma seeped up. A plate in which slits have been cut is used to represent an... (View More) impact basin and a dish of red-colored water is used to represent the pockets of magma within the Moon's upper layers. When the model impact basin is pressed into the "magma," "lava" fills in the low areas through the same process that produced the dark patches, or maria, on the Moon. Children may examine a type of Earth rock (named basalt) that is also found on the Moon and that would have been shaped by the processes explored here. This station investigates the Moon's "teen years," when it was one to three billion years old. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

Learners model how impacts throughout the Moon's history have broken rocks down into a mixture of dust, rocks, and boulders that covers the lunar surface. They consider how the dust will continue to hold a record of human exploration - in the form... (View More) of astronaut bootprints - for countless years in the future. Children may examine a type of Earth soil ("lunar soil simulant") that is similar to what is found on the Moon's surface and that would have been shaped by the processes explored here. The children create their own records of exploration by making rubbings of their shoes. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

Learners will model ancient lunar impacts using water balloons. By measuring the diameter of the crater area, they discover that the Moon's largest impact basins were created by huge asteroids. The huge basins formed on the young Moon, but through... (View More) processes investigated in Moon Ooze, they later became filled in by the dark maria now visible on the Moon. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)

Learners model how an ocean of molten rock "magma" produced the Moon's oldest rocks. Dense materials in the molten mixture sank, while the least dense materials floated to the top and cooled to form the light-colored areas we see on the Moon today.... (View More) Children create a simple model of this process by mixing household materials of different densities in a bottle and allowing them to settle into separate layers. They decide which materials make the best model for the infant Moon. This activity is part of Explore! Marvel Moon, a series of activities developed specifically for use in libraries. (View Less)
