B2 Inclusion: Greenhouse effect in a drinking cup (student instructions for lower level)

Experimentation instructions:support students in conducting the "B2 Inclusion: Greenhouse effect in a drinking cup” experiment at different levels For each subexperiment, the students are first provided with an overview of the materials to be used and safety information. This overview is followed by the detailed, step-by-step instructions for conducting the experiment. Afterwards, the students are asked to note their observations. Specific questions are used to guide the students as they analyze the results of the experiments. At the end, the students are asked in-depth questions related to the experiment.

Is the greenhouse effect caused by people?

%nformation module:Without the natural greenhouse effect, there would be no life on earth. But the greenhouse gases such as carbon dioxide and methane are reinforcing the effect in a way that is harmful.The aim is for students to recognize that life on earth as we know it would not be possible without the greenhouse effect. Three scenarios are presented for this: the earth without the greenhouse, the natural greenhouse effect and the anthropogenically enhanced greenhouse effect. The module shows how the complete lack of a greenhouse effect would affect the earth, how the natural greenhouse effect works and why there is an additional, undesired anthropogenically enhanced greenhouse effect. In the case of the anthropogenically enhanced greenhouse effect, an animation shows where the rise in greenhouse gases comes from and how this affects the average temperature on the earth's surface through increased counter-radiation. For the individual greenhouse gases, information can be accessed interactively on the wavelength range within which the thermal radiation is scattered back to the earth.Information and ideas:For the direct reflection of the incoming radiation, an albedo (reflection capacity of diffusely reflecting surfaces such as ice and snow) of approx. 0.30 is assumed with and without atmosphere, since the earth is not an ideal black-body radiator.The anthropogenically enhanced greenhouse effect and changes in solar activity are the main causes of climate change! Scientists have agreed that both effects influence the earth's climate. What has not yet finally been determined is the percentage effect of each factor on the changes in the climate of the earth. In terms of specialist teaching, this subject involves some complex physics. One of the most difficult questions is the matter of radiation balance: Why does it get warm on earth although almost 100% of the earth's energy is radiated away%

B2 Greenhouse effect (worksheet 1)

Worksheet for subject teaching in English:
For the student experimentation instructions of the same name. Methodology tool: cloze test developed by Josef Leisen and Heinz Klippert.


Note: This worksheet has been developed especially for subject teaching in English and for language-sensitive subject teaching. It uses the cloze test methodology tool developed by Josef Leisen and Heinz Klippert. The cloze test is used to review and summarize a topic. It is also suited for internal differentiation.
Students whose native language is not English and who do not have strong English skills receive support and training in understanding the technical vocabulary. They work with the specialized vocabulary and in this way acquire the ability to communicate about specific subjects.

The greenhouse effect and climate change

Information sheet:The heat radiated by the earth does not reach outer space unimpeded; some of it is absorbed and reflected in the earth's atmosphere. Without this effect, we would be living in a permanent ice age on earth.This information clears up the prejudice that the greenhouse effect is basically something negative. Without the natural greenhouse effect, life on earth would not be possible at all. The gradual increase in global warming, however, is the result of an anthropogenically caused greenhouse effect. The differences are explained. In addition, the fundamental physical facts are presented, i.e. the radiation balance and the radiation absorption of molecules.Information and ideas:You can have your students look for possible ways of reducing the anthropogenically enhanced greenhouse effect in the short, medium or long term. Political, economic and personal aspects can be discussed separately.
