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)

This is a lesson about measurement and cratering. Learners will read about the origin of the foot as a standardized unit of measure, work collaboratively to conduct an experiment about cratering, and collect and record data to draw logical and... (View More) scientific conclusions. The lesson uses the 5E instructional model and includes: TEKS Details (Texas Standards alignment), Essential Question, Science Notebook, Vocabulary Definitions for Students, Vocabulary Definitions for Teachers, three Vocabulary Cards, and a Mini-Lesson. This is lesson 7 of the Mars Rover Celebration Unit, a six week long curriculum. (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. (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. (View Less)

This is a lesson about determining planetary composition. Learners will use a reflectometer to determine which minerals are present (from a set of knowns) in a sample of Mars soil simulant. Requires the use of ALTA II spectrometers (which may be... (View More) borrowed from the Lunar and Planetary Institute or purchased online) and Mars soil simulant. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)

This is a lesson about the shape of objects in space. Learners will observe the surface of rotating potatoes to help them understand how astronomers use variations in reflective brightness to determine the shape of asteroids.

This is a lesson about infrared radiation. Learners will investigate invisible forms of light as they conduct William Herschel’s experiment and subsequent discovery of infrared radiation. They will construct a device to measure the presence of... (View More) infrared radiation in sunlight, explain that visible light is only part of the electromagnetic spectrum of radiation emitted by the Sun, follow the path taken by Herschel through scientific discovery, explain why we would want to use infrared radiation to study Mercury and other planets, and explain how excess infrared radiation is a concern for the MESSENGER mission. This is activity 1 of 4 at the Grade 5-8 band of "Staying Cool." (View Less)
