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:
Wood + plastic accessories + hardware accessories + bulb + alligator clip + negative plate + positive plate + foam ball.
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.
Seaplane: refers to the aircraft that can take off, land and park on the water. Mainly used for maritime patrol, anti-submarine, rescue and sports, tourism, commuting, aerial photography and so on.
Aquatic aircraft and amphibious aircraft, aquatic aircraft and divided into airship and buoy aircraft. For example, China's water h-5, which first flew in 1976, can only take off and land on water and then climb back to its shore base like an alligator, while its successor, the jiaolong 600, rolled off the assembly line in 2016, is an amphibious aircraft.
Structure type: hull type and buoy type.
Scale type: small one or two engines, large four engines.
Engine type: concealed type and abductor type.
Seaplane refers to a modern technological aircraft that takes off, lands and stops on water, including oceans, lakes and rivers.
There are two types of seaplanes: hull (a specially shaped fuselage designed to glide on the surface of the water) or buoy (replacing the landing gear of a land plane with a buoy).
Seaplanes fly at altitudes of 600m to 800m to fill gaps in low-altitude three-dimensional traffic. [1]
Type of habitat: aquatic aircraft; Amphibious aircraft.
Why seaplanes can take off and land at sea seaplanes can adapt to water and air two different environments, and its special design is inseparable. Let's say it's a ship, but like an airplane it has a fuselage, wings, tail, propeller, and landing gear. Let's say it's an airplane, but its fuselage is a huge, axe-shaped hull. This unique feature makes it a true \"all-round player\".
Basic principle:
When a seaplane is moored, the buoyancy of a large hull keeps the plane afloat without sinking. But when it needs to take off, the pull of the propeller engine drags it along the water at a fairly fast speed. With increasing speed, the lift generated on the wings slowly overcomes the plane's gravity and gradually lifts the plane from the water to become a ship in the air. After completing its mission in the air, it naturally returns to the surface of the water to become a boat that can glide on the water. Therefore, many people abroad according to the characteristics of the seaplane, it is called seaplane or aircraft cruiser.
