Petri dishes in the Styrofoam Styrofoam box with thermometer The picture at the top shows how we placed the petri dishes in the Styrofoam box along with the light bulb to maintain a temperature in the Styrofoam box between 25 – 30 °C. The picture at the bottom shows the Styrofoam box and the thermometer we used to record the temperature Readings / Data: We repeated the experiment three times, so we could look for trends and anomalies. Set 1 reading I touched sector 1 with a finger, straight after playing with the dog. This means hands were not washed before touching sector 1.
