From the ancient night travel by candlelight to today's night view, electricity has become increasingly important. Thanks to the progress of human science, now nature can also generate electricity, such as solar energy, wind energy, geothermal energy and so on.

We all know that
The wind can generate electricity, the tide can generate electricity
Do you understand that
Today, let's learn how brine power works

Experimental purpose:

Develop students' ability of analyzing and thinking

Understand the working principle of brine power generation


Experimental materials:
Open the material package: wood + plastic accessories + hardware accessories + light bulb + crocodile clip + negative plate + positive plate.

Experimental steps:

Experimental principle:

Copper and zinc react in brine (electrolyte). Zinc loses electrons and copper gains them, generating an electric current that lights up the LED. Saltwater does not need any batteries to generate electricity. It only needs a little saltwater to make the LED lights light up. It can help children learn about green energy and develop the good habit of environmental protection from an early age.

We 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 mode, which is a kind of oxidation reaction. Its power generation principle is: AL+O2--AL2O3   Mg + O2 - MgO style
The metal and metal oxidation are non-toxic, harmless, environmentally safe substances. During the process of generating electricity, the black film continuously absorbs oxygen from the air. With the help of salt water, oxygen and water oxidize the metal aluminum and magnesium into metal oxides.

Similar phenomenon: metal iron will rust in wet and rainy environment. The process is that, under the action of water and air, the elemental iron is gradually oxidized into red iron tetroxide. And the transformation of electrons that happens in this reaction that we capture, we can bring electrons to humans. This kind of battery is commonly referred to as air battery, air battery has been gradually applied to the automotive, outdoor power generation, outdoor lighting and other fields

The students have a deep understanding that the oxidation of simple metals into oxidation (the main component of bauxite, iron ore and magnesium ore) can release energy, and the oxide (the main component of bauxite, iron ore and magnesium ore) can become simple metals under the action of electric decomposition (electrolysis), commonly known as steel making, iron smelting and aluminum refining. Among them, metal elemental oxidation gives off electric power, which is the reverse reaction of oxide electrolysis to produce elemental. Popular understanding is that electrolysis contains electric power in the elemental metal, while REDOX reaction only releases the electric power contained in the elemental.
