    Tracing the Invisible
    Within the thematic complex of the optics, satellite images apply exceptionally well. The physical basics of satellite remote sensing reach from the recording to the completed satellite image. The goal of the teaching unit "Tracing the invisible" is to convey the interrelations among the electromagnetic spectrum, reflect ion, absorption and the processes of recording and developing satellite images. The teaching unit makes use of the computer’s potentials to effectively convey the subject matter by using and interaction. A computer-based interactive learning module allows a practical consideration of the thematic field and, thereby, shall ease the comprehension of the electromagnetic spectrum invisible for the human eye. Therefore, the pupils get the chance to visualise the spectrum’s infrared range in the satellite image by allocating a colour. Furthermore, the computer-based learning module covers the following aspects of modern learning: The module is science based and, thereby, fosters propaedeutic science learning The module promotes a type of teaching that emphasises the students’ self-activity and self-responsibility. The module considers the students’ life reality. The computer is applied as work equipment. Students learn to use the computer as a tool instead of an information and entertainment medium. Furthermore, the pupils learn how to handle modern media and gain media competence. The teaching unit Tracing the invisible is composed of three different parts: The first part introduces the pupils to the topic reflection by asking them to do trials on the reflection of different objects together with a virtual professor. This part aims at the characterisation of different objects with regards to their reflection patterns. To allow linkages to the everyday life, the first module part focuses on the range of visible light within the electromagnetic spectrum. In the second part, the pupils can then transfer the knowledge they acquired in the virtual lap to a satellite. The overriding goal of this second module part is the comprehension of a satellite’s mode of operation. Therefore, it revolves around the following question: How does a satellite transform the absorbed reflection signals to coloured picture information? In the last module part, the complete electromagnetic spectrum is in the focus and, thereby, the pupils learn about how satellites can process light information aside from the visible one. The active and independent working with the teaching module provides room for intensive dispute on the topic. The comprehension is to be fostered primarily through the various interaction options, and, therefore, interactive tasks have been integrated into the module. The students need to comprehend the contents before being able to advance to the next module part by successfully completing a quiz. This quiz is considered an assistance to the pupils since they are not immediately confronted with the whole matter to prevent over-straining. After successfully completing a module part, the pupils may switch among parts and, thereby, are enabled to look up facts to solve upcoming questions. It is recommended to work on the teaching units in small groups (2 persons) since the pupils can then reflect and discuss experiences and results together. Thereby, the pupils’ capacity for team work is fostered besides their linguistic competence. The pupils’ active involvement changes the role of the teacher to the one of a learning coach, supporting the learning process as a guide, supervisor, and tutor.

    Which of the objects does not have reflection symmetry?
    Multiple-choice test:From four photos or illustrations of everyday objects, the students are to pick out the object that does not have reflection symmetry.The students need to make a visual judgment: Symmetrical designs are incorporated into many objects, but they are not always rendered perfectly. For example, a pretzel actually has reflection symmetry, but some pretzels are a bit crooked.

    Crafts with reflection symmetry
    Craft instructions:Paper is folded once or multiple times and cut on the edges using scissors. Delightful inkblot pictures with reflection symmetry are created from drops of paint or ink on paper that is then folded and pressed.The folds in the paper are visible axes of symmetry, across which the patterns are reflected, whether they are cut or blotted. Multiple folds generate patterns reflected multiple times.

    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%

    Symmetry is everywhere
    Photo collage:Symmetrical objects such as those seen all over at home and outdoors.Symmetry is an everyday phenomenon that the students can recognize in many things in their environment if they only look more closely. Also suitable as an incentive for them to explore on their own and look for symmetry.Information and ideas:The jumping jack shown is not purely symmetrical with respect to reflection, but at first glance the students might think it is. The image can be used as a stimulus to motivate the students to design their own jumping jacks with reflection symmetry.

    6. Electricity – 6.1 Simple electrical circuit (teacher instructions)
    Experimentation instructions:Background information on the content and practical information on conducting the “Simple electrical circuit" experiment.Students will: • learn about the materials for doing electronic experiments, e.g. breadboards, experimentation sets. • learn how to use the materials to set up electronic experiments.• experience and learn the basic components of an electrical circuit.• learn about circuit diagrams and symbols for electronic components.One item deals with „Technical application and vocational orientation“.Information and ideas:• Be sure to inform the students about the dangers of electricity and safety measures to avoid them. Point out that the voltage used in the experiment is harmless. However, emphasize that household voltage is much stronger and can be dangerous if handled incorrectly.• Since the students are working with the materials for the first time, explain the individual components and specify their purposes.• The experiment works equally well with an incandescent bulb instead of the buzzer. For our worksheet, we have chosen a buzzer simply because incandescent bulbs are prone to break and must then be replaced. If your students use incandescent bulbs in the experiment, make sure to point out in the ”Analysis and reflection” that the bulbs do not produce light but heat: The wire filament is heated to such a high temperature that it glows with visible light.• Point out the dangers of a battery being short-circuited.• Point out that the circuit diagram uses abstract symbols, which represent real components.
