Aim: To look at climate change and the greenhouse affect

Materials

1. 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

4.  Wait for 5 minutes and start recording the temperature.

Variables:

All water added to the bottles was from the classroom tap

Minutes	Bottle 1: Water	Bottle 2: CO2 Gas
0	18.c	18.c
5	25.c	18.c
10	26.c	25.c
15	No Recording.	No Recording.
20	No Recording.	No Recording.
25	No Recording.	No Recording.
30	No Recording.	No Recording.
35	No Recording.	No Recording.
40	28.c	38.c

Conclusion:

The normal bottle of water didn't get as hot as the CO2 water. This is just the same as climate change. I also found this experiment interesting.
