Answer the following question in your Home Learning Journal.
On the surface, everything looked ordinary.
The boy in the boat was bored. He had lived beside this boring river with his boring family for his whole boring life. Nothing unexpected ever seemed to happen to him. He often went to bed at night and wished for something exciting in his life.
Little did he know, underneath the ground he walked on and the river he rowed his boat on, a marvellous, mysterious, magical menagerie of life stirred.
His life was about to become a lot more interesting…
Think about where there might be a hidden city in your school or home. A place where no-one would bother the inhabitants! It might be under the stairs or inside a bookshelf or even under the floorboards! Can you draw what you have imagined?

DO try this at home!
Before you start, decide how far you’d like your string to span, whether it’s all the way across the room or less. Choose a location so that everyone in your family will be able to see your rocket balloon fly!
A rocket is a vehicle that carries everything it needs with it. Our rocket balloon carries air inside it and that’s what makes it go.
To inflate the balloon you have to blow pretty hard. This is because once you put some air inside, it starts pushing back against you.
Air is made up of particles called molecules, moving around in all directions and at very high speeds. They push against anything they bounce off. When the balloon is inflated and closed off, there are loads and loads of air particles trapped inside. They’re whizzing about, crashing into each other and the insides of the balloon. All these tiny pushes add up to a force that is large enough to hold the balloon in its round shape. The air particles push equally to the left, right, up and down. Overall the forces cancel each other out, they are balanced forces and that’s why the balloon stays where it is.
When you let go, the air can’t push on the part of the balloon where the opening is. There’s nothing to push on. But on the opposite side, inside the balloon, the air is still pushing. The left and right forces aren’t balanced anymore, and it’s this unbalanced force – due to the air particles bouncing off the front the balloon – that sends it forwards.
Real rockets use fuel, but they work on the same principle called Newton’s third law of motion. You may have heard “for every action there must be a reaction”, which means that it’s impossible to move in any direction without pushing something else in the opposite direction. Our balloon rocket moves air backwards for it to move forwards. In a real rocket, the rocket must push fuel downwards (very quickly) to start moving upwards.
You could challenge your family to design the perfect rocket balloon. Here are a few top tips to get you started:
Once you’ve perfected your living room design, can you find a way to launch your balloon straight up like a real rocket?
The Russian Soyuz programme is the longest running and most successful way of getting rockets into space. The programme has been going since 1967 with over 1680 successful launches!
