Physics

Would you like to make sound waves visible or to investigate a movement of a trampoline jumper in your classroom?
That and more is possible with the products of CMA!
With an interface and a set of sensors, such as temperature, sound, light, voltage, motion, force, pressure and many more, students can carry out many different physics experiments. Very fast and very slow rates of data collection provide new contexts for gathering data and expand students’ experience of phenomena. Real-time presenting data while being collected makes data collection an interactive process whereby direct observations may be immediately compared with the graph, encouraging thinking about the data.
Measurement on videos or images allows students to analyze real and attractive events. The events can be rather ordinary, every day events such as basketball shots or soccer kicks or more unusual like jump on the Moon, car crashes or the motion of a manikin as it strikes an air bag during a car collision. In the Data Video of Coach data graphs are synchronized with the video frames; when scanning the data in the diagram the corresponding video frames are shown. This helps students to bridge the gap between the concrete visual display and its abstract graphical representation.
Computer modelling is an important process in scientific research and therefore students should develop understanding of the process as well as acquiring modeling skills. Modelling allows solving complex and realistic problems not just limited to ideal laboratory phenomena. Such realistic problems are normally too difficult to solve analytically at the school level. Using Coach graphical modelling forces the students to engage in a qualitative analysis of the problem. The structure and the relevant quantities have to be defined. Theoretical assumptions become visualized by iconic representations. Students can experiment with ideas. Formulating the (difference) equations becomes the main tasks of students instead of solving them. The model structure is easy to modify allowing trying different modeling ideas. Additionally Coach the model results can be compared with experimental data. The model can be modified to match the data from the real experiment and the theoretical model.
