Unit 11 – Science and Humanity Sept Title: Describe long-term changes that have occurred in our universe to our solar system and earth • Prior learning – The solar system is made up of the sun and 9 planets – The sun is our star • Key words – Star, solar system, planet, distance, temperature, Unit 11 – Science and Humanity Describe long-term changes that have occurred in our universe to our solar system and earth By the end of this lesson we should be able to: • State the components of the solar system (C) • Describe the difference between Comets and meteors.(C) • Explain early thoughts about the solar system (C) Success Criteria: • I have drawn a diagram to show the parts of the solar system • I have described the structure and formation of comets and meteors • I have explained how Copernicus dispelled may peoples theories Unit 11 – Science and Humanity Starter • Do you know the order of the solar system??? • What method do you use to remember this??? Unit 11 – Science and Humanity Hundreds of years ago, people thought that the Earth was the centre of the Universe and that the Sun and planets rotated around the Earth! I don’t think so! Copernicus Nicholas Copernicus, was a Polish astronomer who lived in the 17th century, He studied the stars and discovered that the Earth and the other planets actually rotate around the Sun. Unit 11 – Science and Humanity Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto My Very Easy Method Just Speeds Up Naming Planets Unit 11 – Science and Humanity A01 Describe long-term changes that have occurred in our universe to our solar system and earth Describe the early thoughts about the center of the universe? Unit 11 – Science and Humanity Most of the planets travel around the Sun in near-circular orbits. Comets also travel around the Sun but in very elliptical orbits. For most of its orbit, a comet is a long way from the Sun. The head of the comet is a lump of ice and dust a few kilometres across. The tail only appears when the comet is near the Sun. It consist of gas and dust which are released by the heat of the Sun. Comets Unit 11 – Science and Humanity As the Earth moves Meteors and meteorites through space, it collides with lumps of material which burn up in the atmosphere. These are called meteors and can be seen as streaks of light in the night sky. A large meteor may not burn up completely and hits the Earth with a lot of energy. This is called a meteorite. A meteorite impact is one theory to explain why the dinosaurs became extinct. Unit 11 – Science and Humanity Plenary Unit 11 – Science and Humanity Describe long-term changes that have occurred in our universe to our solar system and earth By the end of this lesson we should be able to: • State the components of the solar system (E/D) • Describe the difference between Comets and meteors.(C) • Explain early thoughts about the solar system (B) Success Criteria: • I have drawn a diagram to show the parts of the solar system • I have described the structure and formation of comets and meteors • I have explained how Copernicus dispelled may peoples theories
