Investigation  Two

 

How does the temperature change in our classroom over an Afternoon?

Investigating Temperature Changes In Year Six

Aim   We are trying to find out how the temperature changes over a period of a day.

Method We 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.Near the outside door. 2.Middle of the classroom. 3.Near the window.

 

 

 

Predictions

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 wont 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.

Results

The sensor readings were displayed on a laptop.

 

 

 

Explanation of results

    1.Door Area. The temperature rose from 11C--16C between 1pm and 2pm, it then dropped to 7C at 2:45. The temperature then rose again to 10C at 3:05, after that it dropped to 2C at 3:15, our survey stopped at 3:30 when the reading was still 2C.

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 19C--19.5C, then at 3:05 it rose to 20C, straight after that at 3:30 the temperature dropped suddenly to 18C At the end of our survey when it was 3:45 the temperature was 19C.                                                                                                                                                                                              3.Window. The temperature stayed roughly the same all the way through the survey. The readings show the door temperature was 15C at 1pm and at 3:30 the temperature was 14.5C. The biggest drop was at 2:30 when it dropped to 14.5C the temperature then rose back to 15C.

Conclusion

   1.Door Area. At 2pm the temperature rose dramatically to 16C because the door was shut, the temperature dropped at 2pm to 7C because the door was opened allowing the cold temperature outside to come inside. The temperature then rose at 2:45pm to 10C 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 15C because the glass is a thermal conductor which allowed the temperature outside to come into the classroom.
