Discovery Primary Science Activities 2

In Room 4 we are conducting lots of experiments! We are learning about Space and this week we looked at how to launch a rocket. We had so much fun. We are super scientists and rocket launchers!

Rocket Launch

Equipment:

• large balloons
• string
• drinking straw
• clothes-peg
• sellotape
• 2 chairs

Skills:Investigating and experimenting

Activity:

1. Make predicitions about what will happen
2. Blow up a balloon and let it go
3. Note what happens
4. Now control the path of the balloon by connecting it to a piece of string
5. Pull the string through a drinking straw
6. Tie the string to two chairs and pull it tight
7. Blow up a balloon and keep the air in it using a clothes peg
8. Using sellotape attach the balloon to the side of the straw
9. Pull the whole thing back to the beginning of the string and take off the clothes peg....launch your rocket!

Results:

• The first balloon flew all over the room when the air was released
• The second balloon whizzed along the string and flew in a straight path

Conlcusion:

The air coming out of the back of the balloon pushes the balloon forward. this is how rockets work- the hot burning gases rushing out the back of the rockets push them forwards.
