Year 5 enjoy science afternoon
Posted on: 02 Mar 2017 by Weston Green School | Category: Key Stage 2, Year 5
Year 5 were treated to a workshop by the head of Chemistry and the head of Physics from Epsom College on Wednesday afternoon. First the students were set the task of designing the best and lightest insulation to protect a transmitter that was to be launched by a high altitude balloon. Surprisingly polystyrene balls in a polystyrene cup proved to be the most insulating!
Next the students were given a lesson in basic programming using the ASCII programming language. They were able to show how letters and symbols could be turned into binary code. This is how their transmitter was going to send data on the balloon's height, GPS position, speed and external temperature.
Finally it was launch time. The 1m diameter helium balloon was launched from the playground. It was last recorded at an altitude of 3,689m, so we wait in anticipation to see if it will beat Epsom's current record of nearly 24,000 metres (twice the cruising height of a Jumbo Jet).
