• Space Science Education Resource Directory - hundreds of resources by science type (earth, physical, or space) or by grade range. Topics include algebra, atoms, big bang, black holes, comets, cosmic distances, energy, force and motion, geometry, graphing, gravity, heat, light and color, measurement and estimation, planets, satellites, solar energy, solar system, space missions, stars, telescopes, and waves.
• Space Weather Center - explores the solar cycle, solar wind, Earth's magnetic field, the ionosphere, auroras, states of matter, plasma (which makes up 99% of visible matter in the universe), & other sun-earth topics. Online games let students launch solar particles at Earth, bowl with protons, & watch charged particles move in magnetic fields. Information is provided on space weather research, space weather modeling & forecasting, & the National Space Weather Program.
