The whole of Year 2 looked at the effects of climate change on global warming. We found out that the earth is surrounded by an atmosphere and around the atmosphere is a layer of greenhouse gasses. We discussed the increase of greenhouse gasses and the effect this has on our planet.
We set up an experiment that compared two identical trays containing a house brick and two ice cubes. One tray was wrapped in cling film to represent this increased layer of greenhouse gas. Over the session we observed the change in the ice cubes and we times how long they took to melt.
We found that the ice cubes in the tray that had been wrapped in cling film, melted quicker than the tray without the cling film. This helped us to understand that heat that had been trapped under the cling film, just as heat from the sun is also trapped around the atmosphere, causing the planet to heat up.
We talked about the impact this has on the planet and how we can help slow this problem down!
