Sharks, living in the ocean, are fish in the sea. Sharks have existed on Earth for more than three hundred million years before the appearance of dinosaurs, and have survived for more than five hundred million years. They have changed little over the past hundred million years. In ancient times, sharks were called "sharks," "shark sharks," and "sandfish." They are giant creatures in the ocean, so they are known as "sea wolves." Traditional beliefs hold that the cartilage in sharks (i.e., shark fins) contains a high protein content, but this is incorrect. The protein in eggs far exceeds that of shark fins. In addition, studies have shown that due to the ease of accumulating mercury in sharks and the presence of certain neurotoxins in shark fins, they pose potential hazards to human health. Due to massive hunting over the past few decades, sharks are at risk of extinction.

Science Project:

 1. Recognize and prepare the necessary materials for the experiment.

Step 2: Install according to the instructions in the manual.

3, Install and debug.

 Scientific Principles:

 The battery delivers electricity to the motor, which converts the electrical energy into mechanical energy to drive the propeller, which rotates at high speed to push the boat forward using the principles of aerodynamics.

Science Expansion:

 Motorboats are the 'short-distance sprinters' of the naval fleet, with speeds of up to 40-60 knots, earning them the nickname of 'marine light cavalry.' Motorboats are classified by their weaponry into torpedo boats, missile boats, and missile torpedo boats, etc. Although small, motorboats have considerable power and a significant role. For large or medium-sized enemy warships that have intruded into the near-shore range, torpedo boats and missile boats can be deployed individually or in coordination with other surface vessels to destroy the intruding enemy vessels. They can also be sent to attack enemy convoys to disrupt enemy maritime transportation lines. The speed of motorboats is fast, and their small size allows for stealth and effective surprise attacks on enemy bases and anchorage areas. In shallow channels, narrow seas, reef and island areas, motorboats can be used for mine laying. Among motorboats, the most powerful are missile boats, which inherit the advantages of torpedo boats and have a very important position in naval warfare. However, compared to large or medium-sized vessels, their self-defense capabilities are weaker, and their performance in rough seas is poor.Only suitable for combat in the near sea. Modern fast boats are widely applied with advanced missile weapons, miniaturized electronic equipment, high-power gas turbines, and water wings and air cushion technology. They are developing towards missileization, large-scale, high-speed, and electrification. In the future, fast boats will play a greater role in sea battles.
