Any questions, use the same email address, or for parents; post in Facebook, or message a leader.

There are some extra activities which you could do below!

Fruit Salad Solar System

You might not be able to find some of the things that this activity suggests that you use, but have a look around the house to see what you can find that might be a similar size!

The whole of space

• We aren’t sure how big space is, because not all of it contains visible light – this means that we can’t measure it
But we do know that it is 13.8 billion years old!

• A galaxy is a large group of stars, held together by gravity
Our galaxy is called the Milky Way

• One of the stars in the MilkyWay is the Sun
8 planets (including Earth) orbit the sun and make up our solar system

Our Solar System

• Mercury (peppercorn) – this is the smallest planet, and the closest to the sun
• Venus (blueberry) – this planet spins in the opposite direction to the other planets and is covered in volcanoes
• Earth (grape) – ¾ of our planet is covered in water
• Mars (dried cranberry) – also known as ‘the red planet’, because it is covered in a mineral called iron oxide, which gives it it’s colour
• Jupiter (grapefruit) – the largest planet in our solar system, all the other plants in the solar system could fit inside it!
• Saturn (orange) – the second largest planet and the lightest planet because it is made almost entirely of gas
• Uranus (small satsuma) – the coldest planet in the solar system
• Neptune (plum) – this name comes from the Roman god of the sea because of it’s deep blue colour, it is roughly the same size as Uranus

Can you come up with a rhyme (a.k.a. mnemonic) to remember the order of the planets?
e.g. My Very Easy Method Just Speeds Up Naming

You might be thinking that we’ve missed Pluto, but in 2006 scientists decided on a clearer definition of the word ‘planet’, which Pluto no longer matched with. It is known known as a dwarf planet, it is smaller than our moon!

The sun is about 109 times the diameter of the Earth! In fact, it is so large that you could fit about 1,300,000 Earths inside it! (You probably won’t find a fruit big enough to represent that!)
