6th Grade Science / Lesson 3 - Sun an Important Energy Source

Sun an Important Energy Source

What will we be learning today?

  • In this lesson, we are going to learn about how the sun is an important energy source.

  • How Is the Sun an Important Energy Source?

    The Sun is the energy source for life on Earth. Light from the Sun is necessary for the growth of plants. Plants and other of Earth's producers trap the Sun's energy and use it in their food-making process. Food made by producers is necessary to pass energy on to all other
    living things.


    Fossil fuels that we use today-coal, oil, and natural gas-were formed over time from the decay of ancient living things. It is a chain of energy from the past to today. The Sun's energy became trapped in ancient producers, which became food for other living things. The energy was stored in the fuels that formed over time.


    The Sun also provides energy for events involving nonliving things. For example, the Sun is the source of energy for the water cycle. The Sun's energy causes ocean water to evaporate. As the evaporated water rises, it forms clouds. Water eventually returns to the ground when it rains. This water may fall into oceans, rivers, and lakes. It may also fall on land. Uneven heating of Earth's surface causes winds and contributes to surface ocean currents.
