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) longer reflecting the Sun’s light in the nighttime or daytime sky. This activity is part of Explore! Marvel Moon.

Learners will explore Jupiter's origins through three stories. First, they model their own lifetimes by tying knots in lengths of yarn to represent key events in their pasts. Then, children listen to and act out a cultural origins story, such as the... (View More) Skytellers stories told by Native American master storytellers. Finally, they explore Jupiter's story by modeling a timeline from today back to its "birthday." They use the timeline to visually demonstrate that the Big Bang occurred much earlier in the past. Children will discover how the Juno mission to Jupiter will help unveil how our solar system - including Earth - came to be. The activities are from Explore! Jupiter's Family Secrets, a series designed to engage children in space and planetary science in libraries and informal learning environments. (View Less)

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) that even a large, massive planet - such as Saturn - can have low density. They discuss how a planet's density is related to whether it is mainly made up of rock or gas. 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. (View Less)

Learners will shrink the scale of the solar system to the size of their neighborhood and compare the relative sizes of scale models of the planets, two dwarf planets, and a comet as represented by fruits and other foods. This activity requires... (View More) access to a large indoor or outdoor space (measuring at least 190 feet wide) where the children can model the orbit of Mercury around the Sun. It 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. (View Less)

This is a lesson about using light to identify the composition of an object. Learners will use a spectrograph to gather data about light sources. Using the data they’ve collected, students are able to make comparisons between different light... (View More) sources and make conjectures about the composition of a mystery light source. 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 an activity about constellations. Learners will make a "star finder" toy and play a game to find a constellation in the night sky.

This is a lesson about detecting atmospheres of planets. Learners will explore stellar occultation events (by interpreting light curves) to determine if an imaginary dwarf planet “Snorkzat” has an atmosphere. The activity is part of Project... (View More) 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 an activity about detecting elements by using light. Learners will develop and apply methods to identify and interpret patterns to the identification of fingerprints. They look at fingerprints of their classmates, snowflakes, and finally... (View More) “spectral fingerprints” of elements. They learn to identify each image as unique, yet part of a group containing recognizable similarities. 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 elemental spectra. Learners will compare known elemental spectra with spectra of Titan and Saturn’s rings from a spectrometer aboard the NASA Cassini spacecraft. They identify the elements visible in the planetary and lunar... (View More) spectra. 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 emission spectra. Learners will look at various light sources (including glow sticks and christmas lights) and make conjectures about their composition. The activity is part of Project Spectra, a science and engineering... (View More) program for middle-high school students, focusing on how light is used to explore the Solar System. (View Less)
