On Readworks, our task was to read the text, and then we had to write two or three sentences of what we have learned. I had fun reading and writing the text because it helped me learn more things about the laws of energy.
I have learned that energy is neither created nor destroyed. I have also learned that a car engine burns gasoline, converting the chemical energy in gasoline into mechanical energy. Another thing I have learned is that most energy transformations are not efficient. The human body is a good example. The human body is like a machine, and the fuel it requires is food.
