Hurumanu - The Greenhouse Effect

Aim: To look at Climate Change and the Greenhouse Effect.


Materials:
1. Plastic bottle
2. 1 Teaspoon Baking Soda and Citric Acid
3. 1 heat lamp
4. 1 thermometer.
5. 100 ml water
6. 1 rubber bung


Steps:
1. Collect materials from Mr Palmer.
2. Setting up the lights, bottles, thermometers and bungs.
3. Mr Palmer adds the Baking Soda Mix with 100 ml of water.
4. Wait for 5 minutes and start recording the temperature.


Variables:

All the water added to the bottles was from the classroom tap.



Findings: The Greenhouse Effect data.

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.
