Dear students;
I upload for you the solutions of exercise 2 (p. 93).
IMPORTANT: Most of you have sent me the activity just by joining the letters and the numbers without writing the whole information from each sentence.
I would not suggest you to do that. First of all because at the moment of studying and reviewing the unit, most of you will use your notebook and hence, you will not know what information belongs to each sentece in the exercise. Bearing this in mind, in the following exercises, you will have to write down the whole sentences. If you do NOT do that, sorry, but I will not mark your exercise. You are older enough to write down information. Come one guys! Do not make use of the "lazy law"! ;)
A) Oersted discovered ... (5) that electricity and magnetism are connected.
B) He noticed that... (3) an electric current affects a compass needle.
C) Ampered discovered ... (4) the particle that is now called the electron.

E) A moving magnent ... (1) can produce electricity with a turbine.
