Have a preliminary understanding of the working principle of saltwater power generation
Experimental materials
Wood + plastic fittings + hardware fittings + light bulb + alligator clip + negative electrode sheet + positive electrode sheet + foam ball.
Experimental procedures
Experimental principle
Copper sheets and zinc sheets undergo a chemical reaction in salt water (electrolyte). When the zinc sheet loses electrons and the copper sheet gains electrons, an electric current is generated, thereby lighting up the LED lamp. Saltwater power generation doesn't require any batteries. Just a little salt water can turn on the LED lights, which can help children understand the knowledge of green energy and develop good habits from an early age.
Everyone should develop the good habit of saving electricity!

Introduction to saltwater power generation: Saltwater power generation is a safe, hygienic and hygienic power generation mode, which is a type of oxidation reaction. Its power generation principle is: AL+O2- AL2O3, Mg+O2- MgO
Among them, both metallic elements and metal oxides are non-toxic, harmless and safe substances. During the power generation process, the black power generation film constantly absorbs oxygen from the air. With the help of salt water, oxygen and water oxidize metal aluminum and metal magnesium into metal oxides.
Similar phenomenon: Metallic iron will rust in a damp and rainy environment. The process is that under the action of water and air, elemental iron gradually oxidizes to red ferric oxide. The electronic transformation produced in this reaction process, if captured by us, can bring electrons to humans. This type of battery is commonly known as an air battery. Recently, air batteries have been gradually studied and applied in fields such as automobiles, outdoor power generation, and outdoor lighting
Students have a deeper understanding that the oxidation of metallic elements into oxides (the main components of bauxite, iron ore and magnesite) can release energy, while oxides (the main components of bauxite, iron ore and magnesite) can be transformed into metallic elements under the action of electrical decomposition (electrolysis), commonly known as steelmaking, iron smelting and aluminum smelting. Among them, the oxidation of metallic elements releases electricity, which is the reverse reaction of the electrolysis of oxides to produce elements. In simple terms, electrolysis stores electricity within the elemental metal, while the REDOX reaction merely releases the electricity stored within the element.
Seaplane: It refers to an aircraft that can take off, land and anchor on water, abbreviated as "water machine". It is mainly used for maritime patrol, anti-submarine, rescue, sports, tourism, commuting, aerial photography, etc.
Habitat types: Aquatic aircraft and amphibious aircraft. Aquatic aircraft are further classified into airships and buoy aircraft. For instance, the Shui-H-5, which made its first flight in 1976 in China, could only take off and land on water and then crawl back to the shore base like a crocodile. Its successor, the Jiaolong 600, which rolled off the assembly line in 2016, is an amphibious aircraft.
Structural types: Hull type and float type.
Scale type: Small with one or two engines, large with four engines.
Engine type: Concealed type and outward-mounted type.
Seaplanes generally refer to modern technological aircraft that take off, land and dock on water surfaces, including oceans, lakes and rivers.
Seaplanes are divided into two types: the hull type (i.e., a specially shaped fuselage designed according to the requirements of gliding on the water surface) and the float type (replacing the landing gear of land aircraft with floats).
Seaplanes fly at altitudes ranging from 600 to 800 meters, filling the gap in low-altitude three-dimensional transportation. [1]
Habitat type: Aquatic aircraft; Amphibious aircraft.
Why can seaplanes take off and land at sea? The reason why seaplanes can adapt to both water and air environments is inseparable from their special design. If it were a ship, it would have a fuselage, wings, tail, propellers and landing gear like an airplane. Suppose it is an airplane, but its fuselage is a huge hull shaped like an axe blade. This unique feature makes it a true "all-rounder".
Basic principle
When a seaplane is moored on water, the buoyancy generated by its wide hull will keep the plane afloat and prevent it from sinking. But when it is time to take off, the pulling force generated by the propeller engine will drag it to slide at a rather fast speed on the water surface. As the speed keeps increasing, the lift force generated on the wings gradually overcomes the weight of the aircraft, thus lifting it up from the water surface and turning it into a ship flying in the air. After it has completed its aerial mission, it will naturally return to the water surface and thus become a ship capable of gliding on water. Therefore, many people abroad, based on this feature of the seaplane, also call it a seaship or an aircraft cruiser.
