On Thursday 6th June, Year 4 had an extremely exciting afternoon. They have been learning about the effects of pressure build up and investigated this through a rocket launch.

Year 4 began by looking at the effect that pressure build up has on the movement of objects. They designed an experiment which would involve seeing if pressure build up would propel a rocket. First, they had to construct rockets in groups using 2litre plastic bottles and card. Through research, they designed their rockets to include a coned nose and fins to enable it to travel the furthest. One of the children said that it was so much fun creating their rocket designs. Once the rockets were constructed they just had to select a fun and imaginative name, such as The Fantastic Four and The Goblet of Fire!

They were now ready for the experiment. Each rocket was half filled with water then a pump was used to create air pressure in the top of the rocket. Whilst waiting for the launch of their rocket a child was heard saying, “I am so excited to see how high our rocket goes, I hope it makes it to the moon!” The rockets were all very successful and managed to soar really high into the air.


 The children really enjoyed their investigation and were able to draw their conclusions on the effect that pressure build up has on a rocket. They are very excited for future science experiments!
