Lesson Plan - Get It!
It's a hot summer day and you are enjoying an ice cream cone. It starts to melt! What is making your ice cream melt?
Did you know the sun is a star?
The sun is the closest star to Earth. This is where people on Earth get their heat and light from. If you were to eat ice cream out in the hot sun, the heat from the sun would cause your ice cream to melt. How do you feel when you stand directly in the sunlight? Share your story with your parent or teacher.
You may have said the sun would make you warm up or feel hot. Without the sun, people would not be able to live on Earth. The Earth would be completely frozen! Happily for all living things, the sun is hot enough to give all living things on Earth the heat and light they need to survive. Even though the sun is ninety-two million miles away from Earth, it is still hot enough to make Earth a livable place for plants, animals, and people.
You know the sun gives Earth light and heat, but how does this heat and light reach Earth? The sun has a core that is extremely hot. The core of the sun is in the middle of the sun. This core transfers energy to the outside layer of the sun. The energy (heat and light) travels through space and to Earth in about eight minutes.
The sun can be found in the middle of the solar system. Everything in our solar system revolves around the sun. This means the Earth moves around the sun. Did you know it takes the Earth 365 days to revolve around the sun one time? Do you know what 365 days is called? A year!
The Earth's revolution around the sun affects the seasons. Do the seasons change in your area? How do they change? Share your answers with your parent or teacher.
The sun is the reason living things are able to live on Earth. Tell your parent or teacher what two types of energy come from the sun.
After sharing the two types of energy that come from the sun, move on to the Got It? section.
