Slide 1: Welcome to the Solar System
- Our Solar System is made up of the Sun, eight planets, and many smaller objects
- Everything in the Solar System travels around the Sun
- It formed about 4.6 billion years ago from a giant cloud of gas and dust
Speaker notes: Ask students if they can name any planets before moving on.
Slide 2: The Sun — Our Star
- The Sun is a giant ball of hot, glowing gas at the centre of our Solar System
- It gives us light and heat that make life on Earth possible
- The Sun is so large that about one million Earths could fit inside it
Speaker notes: Remind students never to look directly at the Sun.
Slide 3: The Four Rocky Planets
- Mercury, Venus, Earth, and Mars are the four planets closest to the Sun
- They are called rocky planets because they have solid, rocky surfaces
- Earth is the only planet we know of that supports life
Speaker notes: Point out where each rocky planet sits in order from the Sun.
Slide 4: The Four Gas Giants
- Jupiter, Saturn, Uranus, and Neptune are the four outer planets
- They are called gas giants because they are made mostly of gases, with no solid ground
- Jupiter is the biggest planet — more than 1,300 Earths could fit inside it
Speaker notes: Show a size comparison image of Jupiter next to Earth if available.
Slide 5: Moons, Rings, and Asteroids
- Many planets have moons — Earth has one, but Jupiter has more than 90
- Saturn is famous for its beautiful rings made of ice and rock
- The asteroid belt between Mars and Jupiter contains millions of rocky chunks
Speaker notes: Ask students what they think it would feel like to stand on Saturn's rings.
Slide 6: Dwarf Planets and Pluto
- A dwarf planet is a round object that orbits the Sun but shares its path with other objects
- Pluto was once called the ninth planet but was reclassified as a dwarf planet in 2006
- Other dwarf planets include Eris, Ceres, and Makemake
Speaker notes: Encourage a quick class debate — should Pluto be a planet again?
Slide 7: Exploring Space
- Humans first landed on the Moon in 1969 during NASA's Apollo 11 mission
- Robotic rovers like Curiosity and Perseverance have explored the surface of Mars
- Space telescopes like Hubble and James Webb help us see billions of kilometres into space
Speaker notes: Show a famous space photo, such as the Pale Blue Dot or a Hubble image.
Slide 8: Amazing Solar System Facts
- Light from the Sun takes about 8 minutes to reach Earth
- A year on Neptune lasts 165 Earth years because it is so far from the Sun
- Scientists believe there could be liquid water — and possibly life — on some of Jupiter's moons
Speaker notes: End with an open question: "Which planet would you most like to visit and why?"
