Science / Design & Technology KS2: Experimenting propulsion with water rockets
Children from Links Primary School in London investigate water rockets.
Dr Yan Wong explains the theory behind rocket power, and the children use plastic bottles filled with water and air pumps to see who can get theirs the furthest.
The most streamlined rocket shape is the most effective.
This short film is from the series The Bloodhound Adventure.
This clip has detailed instructions and guidelines that could be used prior to initiating an investigation into simple water rocket design and construction.
It explains how rockets work and suggests modifications that could help the pupils when predicting their own results in further tests.
A focus on the importance of fair testing and safety could be made, with the latter part of the clip being used to draw together evidence and support findings.
This clip will be relevant for teaching Science or Design and Technology at Key Stage 2 in England, Wales and Northern Ireland, and Level 2 in Scotland.
