learning target

1. By analyzing the advantages of using hydrogen as fuel, we realize that hydrogen energy is the most ideal energy source in the future;

2. Through knowledge review and experimental exploration, it is clear that the energy generated by chemical reactions can not only be converted into light energy, heat energy, but also into various forms of energy such as electrical energy.

1. Clean and efficient hydrogen energy

Activity Area: Understanding Hydrogen Fuel:

1. Heat generated by hydrogen combustion

2. Products of hydrogen combustion

3. Method of preparing hydrogen

Advantages of hydrogen energy:

①Hydrogen combustion releases a lot of heat;

②Wide sources of raw materials;

③The combustion product is water, which is pollution-free.

Hydrogen - an ideal green energy source.
