Place the sheet of glass over the second container. Do not cover the cut out section of the third container. Make a small hole in the side of each container so as the thermometer can be inserted inside the container, use Blu-Tack or Plasticine to cover any gaps between the thermometer and the container. Leave the containers in the sunlight. Record the internal temperature of each container every 5 minutes for 20 minutes.
Display results and draw a conclusion from the data collected.
Students could draw a labelled diagram of their experiment to explain why the temperature changed inside the containers. Apply what happened in the experiment model to the atmosphere. Synthesising Graph the air temperatures recorded from the experiment and write an explanation of what occurred. Display the experiment and the results in the classroom, library or office foyer. Additional Learning Students could explain why people grow plants inside glasshouses in certain areas and why they need to be ventilated and present this to the class or other classes.
