Conclusion:
This week in Science, we have been focusing on Climate Change. We did a experiment on the Greenhouse Effect and we had to get in a group of nine. We wrote all of the materials from the teachers blog down and also followed the steps from Mr Palmer.
The bottle of water didn't heat up as much as the bottle with gas in it. Its the same with Climate Change.
