hurumanu greenhouse effect


AIM: TO LOOK AT CLIMATE CHANGE AND THE GREENHOUSE EFFECT.


    THE GREENHOUSE GASES EXPLAINED.


    The Greenhouse Effect experiment

    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 


    Procedure

    step 1 collect 2 bottles,2 lamp and 2 thermometers from the teacher.

    step 2 set up bottles and lamps beside a power point on a flat surface

    step 3 pour 100ml water and baking soda mixture into one of the bottles

    step 4 start to record your findings taken from both thermometers these must be every five minutes. 





    1. Add 100 mL of water to each of the beakers.
    2. Prepare your lamps. Set them up next to each other with the necks angled so they will just fit over the tops of the bottles. Turn them on so they are ready.
    3. Add Baking Soda mix to one of the beakers, and immediately cover both beakers with cling a rubber bung and thermometer. A tight seal around the edge will work best, and make sure thermometers are left visible so you can record the temperature.
    4. Have students record the starting temperature – it should be the same in both beakers.
    5. Turn the bottles so the thermometer is visible.                             
    6. Record the temperature in both beakers every 5 minutes for 45 minutes or until the temperatures stabilize. At the end, have students answer questions at the bottom of their data sheets.
