We have started Physics with Electricity and now it is already 10 days ago when we came to apply the electromagnetic effect in the construction of a motor. End of last week, one third of the students managed their motors to run. Others might still try at home. In the process we found many batteries getting hot. And now we have moved on to a new topic: the heat. It leads us to the final week where we still have 3 themes to see: Heat, Sound and Light. We will combine these phenomena to see what their natures have in common.
