Information and ideas: • The text in the information sheet of the same name provides help in finding the answer. It also includes a lot of additional information. • The answer can be found in the answer sheet of the same name. These work assignments are designed to open a window to technology within the context of Experimento | 8+. The teacher and students should together go into more detail about technologies that are addressed in the experiments or develop the basic principles of the technical applications shown in the photos in order to reflect on and transfer the scientific knowledge gained in the experiment. Because technology is not a central learning objective of Experimento | 8+, the students are encouraged to examine the technology that surrounds them, but they should not be instructed to carry out extensive research to find a solution. The latter also cannot be expected of the students due to the complexity of the technical applications shown.
