This is an activity about similarities and differences between the Earth and Mars. Learners will investigate how Mars compares to the Earth, working together to create an Earth-Mars Comparison Poster to post in the program facility/library and share... (View More) with their community. Their poster will feature basic facts about Mars and the Earth, as well as a scale model using balloons to represent the two planets. It also includes specific tips for effectively engaging girls in STEM. This is activity 2 in Explore: Life on Mars? that was developed specifically for use in libraries. (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 model the gravitational fields of planets on a flexible surface. Children place and move balls of different sizes and densities on a plastic sheet to develop a mental picture of how the mass of an object influences how much effect it... (View More) has on the surrounding space. 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 experiment to create impact craters and examine the associated features. Then they observe images of lunar craters and explore how the mass, shape, velocity, and angle of impactors affects the size and shape of the crater. This... (View More) activity is part of Explore! To the Moon and Beyond! - a resource developed specifically for use in libraries. (View Less)
This interactive website engages children in a story-based scenario that emphasizes concepts of remote sensing and how NASA scientists use satellite imagery to better understand the Earth's environmental changes. The story features a pigeon named... (View More) Amelia and is set in New York City. Amelia's owner, a young girl named Maria, receives a gift from her grandfather-a camera specially designed for strapping on to a pigeon along with copies of old photographs taken of New York City landmarks. Suddenly, Amelia's flights around the city take on new relevance; she visits the Bronx Zoo, Central Park and Battery Park to take updated pictures of those same landmarks from her "birds-eye" perspective. Through Amelia's adventures, and with some help from a NASA scientist, Maria learns about the history of aerial images, the use of images to detect changes over time, the significance of color, texture and shape in interpreting those images, and the importance of images taken from today's NASA satellites to our understanding of Earth. The story is set in New York City, chosen for its size, diversity and the visibility of prominent features in satellite imagery. (View Less)
This is an activity about comparing images of the Sun in different wavelengths of light. Learners will examine solar images taken by the SOHO spacecraft to look for differences in the features that are visible in the various wavelengths of light.... (View More) This activity requires access to the internet to view or print images of the Sun. This is Activity 7 of the Sun As a Star afterschool curriculum. (View Less)
