Academic Year 3

How can students stop a poison from reaching a dangerous temperature?

This week, Year 3s reached the fifth and final challenge in the Tomb Raiders series. Their task was most precarious. In their possession they had a poisonous liquid. It was frozen, but if it reached the temperature of 10° C it would be warm enough to explode and destroy the world.

The girls had to use their scientific knowledge and decide how best to insulate their poison and prevent it from melting. Small groups worked together, each trialling different materials and methods. Some used many layers of newspaper as insulation, while others opted for foil, cling film, bubble wrap or swathes of material.

At regular intervals they took the temperature of the formula with a thermometer and recorded the results on a graph to determine which insulation method worked the best and why.
