Standard 1.1 Develop a model based on evidence to illustrate the life span of the Sun and the role of nuclear fusion that includes: ● Hydrogen as the sun’s fuel ● Helium and energy as the products of fusion processes in the sun ● The sun, like all stars, has a life span based primarily on its initial mass ● The sun’s lifespan is about 10 billion years ● The energy transfer mechanisms that allow energy from nuclear fusion in the sun to reach Earth
