Explore how Earth serves as our home and its unique place in the solar system, and learn hemispheres, time zones, longitude and latitude, country divisions, and early orbital insights.
Explore why Earth is our unique home and how space viewing changes our perspective. Learn how hemispheres, time zones, longitude, and latitude organize life on the blue sphere.
Explore how earth spins on its axis, undergoes axial procession, and how longitude and latitude pinpoint locations, with Polaris as the north star and auroras linked to solar activity.
Answer assessment questions as you listen, printing or typing responses and revisiting the lesson; the lesson has two slides of questions with on-screen answers shown in white.
Explore cross curricular and extension activities that relate the lesson to political science, history, and geophysics, with downloadable resources in the materials folder.
Explore how the curriculum aligns with state science and technology standards and credits NASA and public agencies for images, with acknowledgments and personal dedications to educators and family.
Discover how astronomy studies celestial objects beyond earth's atmosphere, using light to reveal distance, composition, and motion among stars, planets, comets, galaxies, and black holes.
Describe how solar and lunar eclipses occur when the moon, earth, and sun align, producing partial, annular, and total eclipses, with corona, umbro, and penumbra effects.
Learn how earth passes through comet debris to create meteor showers, and observe meteors as shooting stars with naked eyes from dark skies, lying down, for at least an hour.
Explore how the earth's magnetic field shields us from solar particles to create the aurora borealis and aurora australis, visible near the magnetic north and during solar activity.
The Earth is our home. How many of us can live here? How unique is the Earth in all the solar system? Investigate what the universe looks like from the surface of the Earth and why we divided our planet up into hemispheres, time zones, longitude and latitude. Find out how we took our first steps into orbit around this big blue marble we call the Earth and what it taught us about our own planet – Home.
