Students are tasked with virtually designing a spacecraft to withstand the harsh environment of the Van Allen Radiation belts- the location of many communication, GPS and weather satellites. The details of the challenge, along with videos on... (View More) radiation, a materials list (including descriptions, densities, costs, and testing), and subsystems information are included.

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 activity allows participants to build a paper model of the GPM Core Observatory and learn about the technology the satellite uses to measure precipitation from space. Directions explain how to cut, fold and glue the individual pieces together... (View More) to make the model. The accompanying information sheet has details about the systems in the satellite including the Dual-frequency Precipitation Radar (DPR), the GPM Microwave Imager (GMI), the High Gain Antenna, avionics and star trackers, propulsion system and solar array, as well as a math connection and additional engineering challenges.

Materials Cost: 1 cent - $1 per group of students
This lesson was developed to give participants an understanding of Earth's water cycle. In this one-hour long activity, students participate in a webquest to learn about the water cycle, and then build a mini-model of the water cycle to observe how... (View More) water moves through Earth's four systems. The activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons. (View Less)
Materials Cost: 1 cent - $1 per group of students
In this activity, participants learn about the hydrosphere by making observations and taking measurements. They will go outside and use scientific equipment to investigate temperature, pH and transparency of a body of water. They will use this... (View More) qualitative and quantitative data to understand why it is important to know about the condition of freshwater sources in many places in the natural environment and how these places are connected in the water cycle. Data collection is based on protocols from The GLOBE Program. This activity uses the 5E instructional model and is part of the "Survivor Earth" series of one-hour lessons. (View Less)
Materials Cost: $1 - $5 per group of students
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 an activity about magnetic fields. Learners will study magnetic fields at four separate stations: examining magnetic fields generated by everyday items, mapping out a magnetic field using a compass, creating models of Earth's and Jupiter's... (View More) magnetic fields, and observing aurora produced by magnetic fields on both planets. This activity is part of Explore! Jupiter's Family Secrets, a series designed to engage children in space and planetary science in libraries and informal learning environments. (Note: the activity was adapted for informal education from Magnetic Globe, by Sonoma State University, and Exploring Magnetism, by Space Sciences Laboratory, University of California at Berkeley) (View Less)
In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and... (View More) eventual death. Students discuss the physical concept of equilibrium as a balancing of forces and observe an experiment to demonstrate what happens to a soda can when the interior and exterior forces are not in equilibrium. An analogy is made between this experiment and core collapse in stars, to show the importance of maintaining equilibrium in stars. Finally, students participate in an activity which demonstrates how mass is ejected from a collapsed star in a supernova explosion, thereby dispersing heavier elements throughout the Universe. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive or easily found. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible.

Students are introduced to the periodic table and the concept of atomic elements. The group discusses how all material in the Universe is composed of elements and that the atom is the smallest particle that still has the physical and chemical... (View More) properties of any given element. As an exercise in statistics, the students participate in a counting experiment in which they sample a 'Universe bead mix' (where each bead color represents a different element present in the Universe) to estimate the overall composition of the Universe. They compare their findings of the Universe's overall composition with the composition of various different objects in the Universe that are represented by mixtures of rice, beans and other dried goods in jars. Finally, students are introduced to the idea that hydrogen fusion creates heavier elements inside a star. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive; however, some portions of the preparation can be time intensive. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible. (View Less)
Students are introduced to the scientific tool of spectroscopy. They each build a simple spectroscope to examine the light from different light sources, particularly the Sun (Warning: Do not look directly at the Sun) and artificial lights (e.g.,... (View More) fluorescent or sodium lamps). Students compare the continuous spectrum of incandescent lights and the solar spectrum with the clear spectral lines of the fluorescent or sodium room lights and discharge lamps. They learn how the spectral "fingerprints" of each particular element help astronomers recognize the presence of specific elements in distant astronomical objects. Students are also introduced to the broader electromagnetic spectrum beyond what is visible with our eyes and how scientists observe distant objects using multiple wavelength bands. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive. (View Less)
