BONUS: How to Teach the Solar System to Kids

Your young students may find it difficult memorising the planets of our solar system in order. To make easier and more entertaining, here is an effective method of memorizing all nine planets and their location from the sun, all thanks to Tony Buzan and his wonderful book ‘Master Your Memory‘.

“Imagine that you are standing in front of Sun. See it clearly, feel its heat and admire its orange glow. And there is this planet thermometer, filled with that liquid metal that measures temperature: MERCURY.

The Sun heats up and eventually it bursts the thermometer. All you see is that tiny balls of that liquid metal Mercury on the floor.

Next you see is this most beautiful little goddess standing right next to you. What shall we call her? Yes, VENUS.

Then you see Venus playing with this scattered Mercury. Finally manage to pick up one of the Mercury Globules. She throws it in a giant arc way up in the sky. And this lands in your garden with a big thump. Your garden is on planet EARTH.

Because of the big thump, it effected your next-door neighbor who is a little red faced and about to fume up. Who is this God of War? MARS.

Mars is really furious that he is just about to attack you when, striding you on the scene comes a giant. He calms Mars down. He has an initial J on his forehead that stands for JUPITER.

As you look up to Jupiter, he is wearing this T-shirt with the word ‘SUN’ emblazoned in golden letters. Each of this letters stands for the first letter of each of the three big Planets of the Solar System: SATURN, URANUS and NEPTUNE.

Sitting on Jupiter’s head is this barking dog called PLUTO, laughing his little heart out.”

Now whenever your children want to remember the planets, they simply re-run this story in their minds and voila!
