Section 1
The Sun Produces Energy Through Fusion
In the Sun's core, hydrogen particles collide at temperatures of 15 million degrees Celsius, combining to form helium. This fusion process releases energy that powers our solar system.
In this Grade 6 Earth Science lesson from Chapter 22, students learn how the Sun produces energy through nuclear fusion, converting hydrogen into helium in its core. The lesson also covers how energy flows through the Sun's layers and explores solar features such as the corona, sunspots, and solar wind. Part of a unit on stars, galaxies, and the universe, this lesson builds students' understanding of the Sun's size, composition, and its role as the source of light and energy in our solar system.
Section 1
The Sun Produces Energy Through Fusion
In the Sun's core, hydrogen particles collide at temperatures of 15 million degrees Celsius, combining to form helium. This fusion process releases energy that powers our solar system.
Section 2
Energy Travels Through Sun's Layers
Energy moves from the Sun's core by radiation through the radiative zone, then by convection through the convection zone, finally radiating as light from the photosphere into space.
Section 3
Magnetic Fields Create Solar Features
Strong magnetic fields on the Sun produce sunspots (cooler, darker areas), flares (eruptions of hot gas), and prominences (loops of glowing gas extending into the corona).
Section 4
Solar Wind Interacts With Earth
Electrically charged particles stream from the Sun's corona throughout the solar system. Earth's magnetic field deflects most particles, but some enter the atmosphere, creating colorful auroras near the poles.
