Study Notes
Unit 0: Science
- Science is a method of learning about the natural world, encompassing the knowledge gained through this process
- Scientific inquiry involves various approaches scientists use to study the natural world and propose explanations supported by evidence
- Manipulated variable: In an experiment, the variable that is deliberately changed by scientists
- Responding variable: The variable that changes in response to the manipulated variable
Unit 1: Space Systems
The Earth in the Solar System
- Rotation: The Earth's spinning motion on its axis
- Revolution: The Earth's movement around the Sun in an elliptical orbit
- Orbit: A path an object takes around another object in space
- Earth's orbit is elliptical, averaging 149.597 million kilometers from the Sun
- Gravity: The force that attracts all objects towards each other
- Newton's Law of Universal Gravitation: Every object in the universe attracts every other object
The Sun in the Solar System
- The Sun's interior consists of the core, radiation zone, and convection zone
- The core generates energy through nuclear reactions
- The radiation zone transfers energy primarily through electromagnetic radiation
- The convection zone transfers energy through the movement of hot gas and cooler gas
The Moon
- The Moon rotates and revolves around Earth
- Rotation: The Moon's spin on its axis (approximately 27.3 days)
- Revolution: The Moon's orbit around Earth (approximately 27.3 days)
- Phases of the Moon are caused by the positions of the Sun, Earth, and Moon, and the sunlight reflected on the Moon's surface
- Eclipses occur when the Sun, Earth, and Moon align, casting a shadow on one another (Solar and Lunar Eclipses)
- Tides are caused primarily by the Moon's gravitational pull on Earth's water, creating high and low tides
The Earth's Moon
- Maria (dark flat areas): Hardened rock formed from ancient lava flows
- Craters: Large pits on the Moon's surface
- Highlands: Light-coloured features on the Moon, mainly mountains
- Comparison to Earth: The Moon is smaller and has lower surface gravity compared to Earth
Unit 1: Part 5: Traveling into Space
- Rocket: A device that expels gas in one direction to propel itself in the opposite direction
- Rocket function: Rocket engines burn fuel to create hot gas, expelling the gas to create thrust
- Orbital velocity: The velocity a rocket needs to achieve to orbit Earth
- Escape velocity: The velocity a rocket needs to reach to escape Earth's gravitational pull
- Space Race: Competition between the U.S. and the Soviet Union to achieve space supremacy in the 1950s and 1960s
- Satellite: An object that orbits another object in space
- Space shuttle: A reusable spacecraft capable of carrying astronauts and equipment to and from space, and returning to Earth
- Space station: A large artificial satellite where people can live and conduct scientific research for extended periods
- Space probe: A spacecraft that carries instruments to collect data but does not carry a crew
- Rover: A robot operated remotely or autonomously that moves across the surface of another planet
Battle of Planets
- Mars: A planet with a dry, cold, and rocky surface that is red/orange in colour, named after the Roman god of war for its reddish color
- Potential for life: Whether or not life can inhabit the given planet, looking at the conditions of each planet
