Can Y5 find the best thermal insulator?

Y5 were set the task to investigate the best thermal insulator that could be used as an inner lining for a lunch box! They tested out paper, foil and felt! They used thermometers to check the temperature of ice (at regular intervals) placed in a beaker wrapped with each material. They then used 2graph on Purple Mash to present data in a line graph. They really enjoyed the investigation and worked well in their table teams.
