Modeling the Greenhouse Effect

Aim:
The aim behind this experiment is to investigate the consequences of greenhouse gases by recording and comparing the change in temperature every 3 minutes of a flask filled with CO₂ in comparison to a flask filled with air. Introduction:

The purpose of this experiment is to impersonate the greenhouse affect in our own lab by comparing and measuring the temperatures of greenhouse gases CO₂ compared to air. The experiment will recognize the difference in temperature between the two flasks, and conclude if green house gases CO₂ are actually the main causes for global warming. Hypothesis:

I believe that the flask filled with CO₂ will become hotter then the flask filled with air. The reason is because CO₂ is a greenhouse gas and therefore traps heat. This experiment was done to show the effect of greenhouse gases and prove that they contribute to the rise in temperature of the Earth. By comparing the room temperature air filled and CO2 filled flasks, I will be able to determine whether greenhouse gasses do or not effect global warming.

Matterials:
The materials needed to carry out the experiment were:
A bottle of water
A bottle of sodium bicarbonate,
A bottle of vinegar,
1 tube
1 x data-logging thermometer
Standard lab thermometer
3 one-holed stoppers
Paper and pencil to record the data
Variables:
Independent variable
The distance the flask from the lamp
The amount of sodium bicarbonate
The amount of vinegar
Dependent variable
The change in temperature of the CO and air.

Controlled variable
The heat of the lamp;
The time of the experiment
The time when the temperature will be recorded
Methods:
1) Gather the materials needed.
2) Fill flask one with water.
3) Place it faced down in a bucket of water.
4) In flask two, place 5 g of sodium bicarbonate and 15 ml of vinegar to create a reaction that makes CO₂. 5) Then, place a one-holed stopper with tubing in the flask two. 6) Insert the other end of the tubing into the upside down flask filed with water in the bucket of water. 7) Once the CO₂ has displaced the water in flask one, put a one-holed stopper in it. 8) As a control, have one clean flask, which will be filled with regular room air and place one-holed stoppers in each of them. 9) In your stopper holes of one flask of air and one flask of CO₂ insert a data-logging thermometer and in the other two flasks insert standard lab thermometers. 10) Position the flasks an equal distance away from a 100 watt light bulb and them record the initial temperature, and then changes over 15 minutes at 3 minute intervals.
