Green house effect experiment

Objective The objective is to build a simple and small greenhouse and investigate how trapped infrared radiation affects the temperature within. Share your story with Science Buddies.

This is why we are warm, instead of a lifeless and frigid planet. Secondly, the atmosphere acts as a heat store placed between the relatively warm ground and the cold space, and thereby lessens in a high degree the annual, diurnal, and local variations of the temperature.

Abstract Has the temperature in your house felt hotter or colder recently. He created two black boxes, one with a glass lid and another with a salt lid see illustration below.

Go inside and look over the data. Our atmosphere absorbs the heat coming from Earth, called infrared radiation, and radiates some of it back to Earth. He called this the greenhouse effect.

The greenhouse effect

It also shows the effect of a black surface absorbing the energy from visible light. Suitable software should be used to display the temperature data as a function of time as three lines of different colour on screen s visible to the class.

Observe the Greenhouse Effect in a Jar

History of climate change science The existence of the greenhouse effect was argued for by Joseph Fourier in In part 2, however, replacing the plastic bottles with open beakers removes the restriction on convection. A complex interaction between light, heat, and chemicals make up the greenhouse effect and the chemicals known as "greenhouse gases" in the environment.

The greenhouse effect

Adult supervision is required. However, in the atmosphere there is no door to the outside that one can open. Two of the temperature sensors will be required again in part 2, but without the lead flags.

Recommended for Middle School through High School. Discuss how the container affected the temperature of thermometers. Lay the thermometers in direct sunlight. The thermometer outside of the container is constantly being exposed to air that is constantly changing temperature, as the warm air mixes with passing cooler air.

The trace from that beaker should soon show a higher temperature than the beaker with only air — typically up to 8 degrees higher. Do you know why the last ice age started and why it ended. Did the speed of the increase or decrease of temperatures differ.

Within the region where radiative effects are important, the description given by the idealized greenhouse model becomes realistic. You may build multiple cubes to test how a thicker wrapping of plastic affects the temperature. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision.

Wood tested his hypothesis in a rather fun way. Fourier reasoned that energy, in the form of visible light from the Sun, can easily penetrate the atmosphere to reach the surface of Earth and heat it up, but heat can't easily escape back into space.

Replace the thistle funnel shown with a tap funnel or an unstoppered separating funnel.

Greenhouse effect

Wood reasoned that if trapped heat caused the greenhouse to warm up, then the one with the glass lid should be hotter than the one with the salt lid. Arrhenius predicted that at that rate, there would be global warming in a few centuries. On a larger scale, the greenhouse effect helps keep our planet warm.

The bulb should be fitted in a plain bulb-holder suitably stabilised so that it stands securely on the demonstration bench, and is easily switched on and off by the demonstrator without disturbing the bulb. Now introduce a slow stream of methane from the gas tap into the beaker and observe the effect on the temperature trace.

Now introduce a slow stream of methane from the gas tap into the beaker and observe the effect on the temperature trace. Do you know why the last ice age started and why it ended.

Use your watch, clock or timer to write down the temperature inside and outside the cube every 1 minute. In part 1 the lead foil pieces are for making the 'flags' around the temperature sensors Note 3. InJoseph Fourier, the famous French mathematician and physicist, discovered that gases in the atmosphere might affect the surface temperature of Earth.

The more CO2 in the atmosphere, the more slowly the Earth cools, resulting in a net heating of the atmosphere. Gerlich and Tscheusner had a great example of this, which is, as far as Eli can see, the simplest experiment which captures this key element of the greenhouse effect, put an empty pot on the stove and then put a pot with water on the stove.

Oct 30,  · Greenhouse Project ( ratings) by Danny A. The greenhouse effect is the trapping of heat in the atmosphere. Without the gases in the air, heat from the sun would bounce back into space. Too much gas in the air causes too much heat to be absorbed into the atmosphere, therefore disrupting the earth’s equilibrium (balanced /5().

The experiment showed a clear correlation between greenhouse gases and a raise in temperature. This shows that with increased levels of greenhouses gases, the climate is, without a doubt, rising in temperature.

The Greenhouse Effect Experiments by: Dennis Randall With all the talk about global warming these days, do you know how to explain the greenhouse effect to your kids?

What experiments prove the greenhouse effect? The parameters of a simple experiment will differ from greenhouse effect on a planetary scale, but the presence of the effect is the same for both.

The Greenhouse Effect

The absorption bands specific to the greenhouse gas (and in particular CO2) are well established by science. Prelab: 1. What is the Greenhouse effect?

Is it Getting Hot in Here? Investigate the Greenhouse Effect

The Greenhouse effect is the results of greenhouse gases (methane, water vapor, carbon dioxide, and nitrous oxide) causing some infrared radiation to be trapped in the atmosphere.
