From ancient times of holding candles to enjoy the night, to today's viewing the night scenery, electricity has become increasingly important. Due to the progress of human science, nature can also generate electricity now, such as solar energy, wind energy, geothermal energy, etc.,

We all know
Wind can generate electricity, and tidal energy can also be used to generate electricity.
Do you know about saltwater power generation?
Today, let's learn about the principle of saltwater power generation!

Experimental Purpose:

Cultivate students' ability to analyze and think through hands-on operations

Initial understanding of the working principle of saltwater power generation


Experimental materials:

Wood + Screw + Motor + Battery + Salt + Shaft + Plastic Parts + Clamp + Wire + Bell

Experimental steps:

Experimental Principle:

A chemical reaction occurs between a copper sheet and a zinc sheet in saltwater (an electrolyte). Zinc loses electrons, while copper gains them, generating electricity, which then lights up an LED light. Saltwater power generation does not require any batteries; it only needs a little saltwater to light up the LED light. This can help children understand the knowledge of green energy and cultivate good habits of environmental protection from a young age.

Everyone should develop the good habit of saving electricity!

Introduction to Brine Power Generation: Brine power generation is a safe, environmentally friendly, and hygienic power generation model, which is a form of oxidation reaction. Its power generation principle is: AL + O2 -- AL2O3 Mg + O2 -- MgO
Among them, metal monomers and metal oxides are all non-toxic, harmless, and environmentally safe substances. In the process of generating electricity, the black power generation film continuously absorbs oxygen from the air, with the help of saltwater, oxygen and water will oxidize metal aluminum and metal magnesium into metal oxides.

Similar phenomena: Metal iron will rust in an environment with moisture and rain. The process is that under the action of water and air, elemental iron gradually oxidizes into red iron(III) oxide. During this reaction, the electronic changes produced will be captured, which can provide electrons for humans. This type of battery is commonly known as an air battery, and air batteries have gradually been studied and applied in fields such as cars, outdoor power generation, and outdoor lighting.

Students in-depth understanding, metal monomers oxidized into oxides (main components of bauxite, iron ore, magnesium ore) can release energy, and oxides (main components of bauxite, iron ore, magnesium ore) can be transformed into metal monomers under the action of electricity decomposition (electrolysis), commonly known as steelmaking, ironmaking, and aluminum smelting. Among them, the metal monomers oxidized to release electricity is the reverse reaction of the oxides electrolyzing to produce monomers, which is commonly understood as electrolysis storing electricity in the monomer metal, and the oxidation-reduction reaction is just to release the electricity stored in the monomer.
