Greenhouse Model Temperature

Aim

To investigate the effects of radiation on temperature using the greenhouse model.

Hypothesis

As the greenhouse models are exposed to radiation, both will result in an increase of temperature with the temperature in the closed-ended model increasing at a faster rate than the open-ended model.

Variables

Independent: The open end and the closed end of the model

Dependent: The temperature of two different conditions

Controlled: The distance between the lamp and the greenhouse models, the same type of light, the amount of clay to seal the air and the amount of heating time.

Method

1. 3 microscope slides were fitted together to form a prism, resembling the greenhouse model, shown below. Tape was required in order to stick the microscope

The triangular cardboards that were not attached to the sides resemble there are fewer greenhouse gases affecting the air inside the model and it is a representation of the natural greenhouse effects. On the contrary, the close-ended model is there to show that there are more greenhouse gases that trap more heat in the model than the open-ended model. When radiation passes through the microscope slides in the open-ended model, the air molecules inside absorb the heat like the greenhouse gases, and there’s a little change in temperature over time because there’s no barrier for the heated air molecules to escape and heat energy is lost during the process. Comparatively, the air molecules in the close-ended model absorb more heat than the molecules in the open-ended model because, the cardboards that are attached acts like an extra blanket of atmosphere preventing heat to escape, increasing kinetic energy and affecting the extreme increase of temperature. This can be related to the increase in temperature caused by the

As the greenhouse models were exposed to radiation from the lamp, the close-ended model absorbed more heat and the temperature increased at a faster rate than the open-ended mode supporting the hypothesis. It can be concluded that the knowledge that was gained from conducting this experiment, the activity mirrors the greenhouse effect, but not exactly since it is taken place in the atmosphere. This is related to the real world because there's an interaction between light, heat and air molecules which contribute to the greenhouse gases that are trap representing the air inside the prisms causing an increase in the Earth’s
