How does the temperature change in our classroom over an Afternoon?
Investigating Temperature Changes In Year Six
AimWe are trying to find out how the temperature changes over a period of a day.
MethodWe set up the sensors and left them to run between 1pm and 4pm of a school day.
1.Near the outside door.
2.Middle of the classroom.
3.Near the window.
Plan of Class 6 showing the position of the sensors.

1. I think this sensor will pick up the coldest temperatures. I also think it will rise and fall when the doors open and close.
2.I think the temperature will rise and then get even hotter as bodies come in to the classroom. Then colder as the bodies leave.
3.I think the same will happen to the temperature as no.2. I also think it won’t change as much and be more or less the same all the way through because glass is a conductor and cold from outside will be able to come through.
The sensor readings were displayed ona laptop.
Explanation of results
1.Door Area. The temperature rose from 11°C--16°C between 1pm and 2pm, it then dropped to 7°C at 2:45. The temperature then rose again to 10°C at 3:05, after that it dropped to 2°C at 3:15, our survey stopped at 3:30 when the reading was still 2°C.
2.Middle of the Classroom. The temperature stayed roughly the same all the way through the 3 hours. The only changes were : at 1:15 the temperature rose from 19°C--19.5°C, then at 3:05 it rose to 20°C, straight after that at 3:30 the temperature dropped suddenly to 18°C At the end of our survey when it was 3:45 the temperature was 19°C. 3.Window. The temperature stayed roughly the same all the way through the survey. The readings show the door temperature was 15°C at 1pm and at 3:30 the temperature was 14.5°C. The biggest drop was at 2:30 when it dropped to 14.5°C the temperature then rose back to 15°C.
1.Door Area. At 2pm the temperature rose dramatically to 16°C because the door was shut, the temperature dropped at 2pm to 7°C because the door was opened allowing the cold temperature outside to come inside. The temperature then rose at 2:45pm to 10°C because the door was shut.
2. Middle of the Classroom. The temperature stayed roughly the same, through the three hours, because there was nothing to disturb it. It only changed when the children left the building (people give off heat), also when the door was opened affecting the temperature even when the door was along way away.
3.Window. The temperature was around 15°C because the glass is a thermal conductor which allowed the temperature outside to come into the classroom.
