EarthComm Earth System Evolution: Astronomy and Your Community Activity 7

Here you will find resources to help educators and their students understand the place of our solar system in the Milky Way galaxy; study stellar structure and the stellar evolution (the life histories of stars); understand the relationship between the brightness of an object (it's luminosity) and its magnitude; estimate the chances of another star affecting the Earth in some way.

Here you will find resources to help educators and their students explain electromagnetic radiation and the electromagnetic spectrum in terms of wavelength, speed, and energy; investigate the different instruments astronomers use to detect different wavelengths in the electromagnetic spectrum; understand that the atoms of each of the chemical elements have a unique spectral fingerprint; explain how electromagnetic radiation reveals the temperature and chemical makeup of objects like stars; understand that some forms of electromagnetic radiation are essential and beneficial to us on Earth, and others are harmful.

Here you will find resources to help educators and their students explore the structure of the Sun and describe the flow of solar energy in terms of reflection, absorption and scattering; understand that the Sun emits charged particles called the solar wind, and how this wind affects "space weather."; explain the effect of solar wind on people and communities; understand sunspots, solar flares, and other kinds of solar activities and their effects on Earth; learn to estimate the chances for solar activity to affect your community.

Here you will find resources to help educators and their students measure the major axis and distance between the foci of an ellipse; understand the relationship between the distance between the foci and eccentricity of an ellipse; calculate the eccentricity of the Earth's orbit; draw the Earth's changing orbit in relation to the sun, explain how the Earth's changing orbit and its rotation rate could affect its climate; draw the orbits of a comet and an asteroid in relation to the Earth and the Sun.
