Science is a process of asking questions, investigating and finding ways to explore and reach new understandings. Like what causes day and night? The rising of the Sun and the Moon are daily reminders of the awe and wonder, beauty and power of the universe. Studying the relationships between the Sun, Earth and Moon helps us understand how we experience day and night on Earth.
This term, students have been investigating Earth Space Science. The key ideas develop our understanding of Earth’s dynamic structure, its place in the Universe and the immense scales associated with space.
Students will explore how changes on Earth, such as day and night and the seasons, relate to Earth’s rotation and its orbit around the sun. Students will investigate the processes that result in change to Earth’s surface, recognising that Earth has evolved over 4.5 billion years and that the effect of some of these processes is only evident when viewed over extremely long timescales. Students will explore the ways in which humans use resources from the Earth and appreciate the influence of human activity on the surface of the Earth and the atmosphere.
1. What is the largest planet in our solar system?
2. Where is the world’s largest rock?
3. How much of the water in the world is salt water?
4. Which country was the first to launch a satellite into space?
5. The speed of light is faster than the speed of sound? True or False?
6. Which planet is closest to the Sun?
Did you know?• The Light from the Sun reaches Earth in around 8 minutes.
• The Sun produces a solar wind which contains charged particles such as electrons and protons. They escape the Sun’s intense gravity because of their high kinetic energy and the high temperature of the Sun’s corona (a type of plasma atmosphere that extends into space).
• Planets with strong magnetic fields such as Earth manage to deflect most of these charged particles as they approach.
• While living on Earth might be thought as a little expensive sometimes, at least you get a free trip around the Sun every year.
1. Jupiter (11 x bigger than Earth)
2. In Australia. It is called Uluru (previously Ayer’s Rock)
3. 97% ; Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking
4. USSR /Russia in 1957 called Sputnik 1 satellite.
5. True. The speed of light is faster than the speed of sound.
6. The closest planet to the Sun is Mercury.
