What is it
The MindMap is a simple illustrated presentation of different areas linked to energy. Thanks to the Google maps API the pictures can be moved and it is possible to zoom in on them. On the different zoom levels the information can be presented in more and more detail. So you can switch quickly between the overview and the details.
The MindMap is available online and runs on most browsers independently of the operating system. The information will be updated from time to time, but the users do not have to make any efforts.
What needs to be prepared
Time needed for preparation depends on the previous knowledge of the lecturer but generally it is not much. Lecturers that plan to use the digital MindMap should get an overview on the content and its corresponding position within the MindMap. During the experimenting phase, it is recommended to think about possible tasks for students and to identify specific parts of the presentation that you would like to look at in more detail. If you would like to create more complex topics, that are not included in the MindMap, you should check if there is enough supplementing information available over the internet.
How is it used
One way is to let the students explore the MindMap at home. You can support the process by some easy tasks where the students have to look for information within the MindMap as for example:
- Which criteria are used to compare energy storage?
- What is potential energy?
A more complex task is to compare information within the MindMap:
- How many years of production of fossil fuels are left and why is it difficult to determine?
- Is a fuel cell an energy storage or transformer?
There are also tasks that use information from the MindMap to solve easy calculation and estimation tasks:
- How much energy is stored in a tile falling from a roof?
- How much energy is stored in an falling icicle?
More complex tasks can be solved by doing additional research:
- By how many degrees celsius would the temperature of a glass of water increase when using the energy of the falling tile?
- How many wind turbines are needed to replace a coal-fired plant?
Please note that the last examples were used to illustrate the easy conversions that are possible by using the term energy. The MindMap should improve the understanding of energy. It is not meant to be used only for calculations.
It is also possible to use only parts of the MindMap in a presentation. The zoom levels are available as individual images as well.
