The heat of the sun

Year 5 have been looking at the Earth, the Sun and moon in our latest topic. We did an experiment looking into the heat produced by the sun and how it spreads over the suraface of the Earth. 

We had a test tube tilted to a particular angle to reflect the tilted axis of the Earth.

To make our test fair we made sure the lamp was at the same distance from each of our boiling tubes.

We also made sure that each boiling tube contained the same amount of water.

We started the timer and turned on the lamp (representing the Sun).

We then measured the temperature of the water to see how it changed.

We were sure to record our results.
