CO2 Science Experiment

To warm up or not too. Are we having a severe effect on global warming? We have looked at science behind climate change and learnt what keeps the planet warm – Greenhouse gases, Carbon Dioxide, Methane, Nitrous Oxide and water vapour.

Carbon Dioxide is being examined in-depth. What levels of Carbon Dioxide do emitters actually emit? To reduce the amount of Carbon Dioxide should we all hold our breath? Stop driving cars? Plant more trees? Or not worry about it?

The experiment purpose is to detect the presence of CO2 (carbon dioxide) in a sample gas. We compared concentrations of CO2 in human breath, room air, a chemical reaction, and car exhaust.

Your task is to write up a scientific report of the experiment. Below are the results from 3 classes.

10 07 Drops of Ammonia G1 Drops of Ammonia G2 Drops of Ammonia G3 Drops of Ammonia G4 Drops of Ammonia G5 Drops of Ammonia G6 Drops of Ammonia G7
Control 0 0 0 0 0 0 0
Breath 11 N/A 2 2 4 10 3
Room Air 2 2 1 1 0 1 0
Chemical Air 5 12 N/A 8 12 7 13
Car Exhaust 7 N/A N/A 4 4 4 4
10 05 Drops of Ammonia G1 Drops of Ammonia G2 Drops of Ammonia G3 Drops of Ammonia G4 Drops of Ammonia G5 Drops of Ammonia G6
Control 0 0 0 0 0 0
Breath 6 2 3 2 2 4
Room Air 1 0 0 0 0 2
Chemical Air 5 3 18 N/A 15 6
Car Exhaust N/A N/A N/A N/A N/A N/A
10 06 Drops of Ammonia G1 Drops of Ammonia G2 Drops of Ammonia G3 Drops of Ammonia G4
Control 0 0 0 0
Breath 2 2 2 3
Room Air 0 0 0 0
Chemical Air 11 20 11 20
Car Exhaust 6 6 7 6

Some things to consider is why do the results vary? Is this what you expected? What errors could have occurred in the experiment? What does this show about emitters of Carbon Dioxide emitters?

    Tidal power is the generation of electrical power through the harnessing of the ebb and flow of the tides.

    A barrage is built across a river estuary or bay.The barrage has gates,which allow water to flow into the barrage with the incoming tide.The ebb and flow of the tides turn a turbine which generates electricity.
    Advantages:
    1) Offshore turbines and vertical-axis turbines are not expensive to build and do not have a large environmental impact.
    2) The barrage can help to reduce the damage of very high tidal surges or storms on the land.

    Disadvantages:
    1) A barrage across an estuary is very expensive to build and affects a very wide area-(the environment is changed for many miles upstream and downstream.Many birds rely on the tide uncovering the mus flats so that they can feed.Fish can’t migrate,unless “fish ladders” are installed.

    2) Needs a very big piece of sea to be cost effective and only produces power for about 10 hours of the day

    Hello Mr G, i wasn’t sure if you can send messages on this. I’ve been sick since Wednesday so I didnt have my science books at home, i’ve tried to do the climate change assignment and the carbon dioxide expirement write up but i need my books so i havent been able to do much. Would i be able to talk to you about an extention tomorrow ? Sorry if this is the wrong place to send messages, you can email me if thats easier.

    thanks, emily.

      Hi Emily,

      I’m sorry to hear you’ve been sick. There’ve been a few nasty colds going around; I hope you get over it soon. You have done the right thing by posting here; I will be happy to discuss an extension with you on Monday. If you hadn’t posted here, I would have not granted you an extension without a lot more requirements.
