 Hydroelectric Turbine Course Presentation

I. Experimental Objectives:
1) To make students realize that water has the power to flow.
2) Guide students to learn the method of comparative experiments
 
Experiment Focus:
Understanding the Basic Principles of Waterwheel Rotation
 
III. Experimental Equipment and Cognition:
1. Knowledge Points:
A、The concept of waterwheel:
Water has the power, and this power is called hydro-power. Water mills are old-style mechanical devices that use water flow as their power source.
B. The speed of the waterwheel's rotation is related to what?
① Water-related, the higher the water level, the faster the small waterwheel turns.
② It is related to the water flow rate, the greater the water flow rate, the faster the small water wheel turns.
 
Step 4: Experimental Procedures
Assemble the waterwheel blades. Insert the small iron shaft into the middle of the waterwheel blade, and then assemble the A-shaped support and base together. Assemble the assembled waterwheel blade and support together.
② Find a basin or other container for holding water (if you have a small water tank at home, you can also use it), and find a mineral water bottle or other soft drink bottle. Make a small hole in the lid, and fill it with a certain amount of water. The opening end should be directed towards the water wheel blades to inject water, and observe the rotation of the small water wheel. If you accelerate the water flow above the water wheel blades, the rotation of the small water wheel will accelerate.
③Think of any other ways to make the waterwheel turn faster? Students can try to raise the water bottle and see if the waterwheel turns faster? Students can also prepare another water bottle, open a large hole on the cover, and inject water flow towards the blades of the waterwheel, and see if the waterwheel turns faster?
Five, Knowledge Expansion
1. Our country had the prototype of water-powered mills, called "shui zhui," as early as the Western Han Dynasty. It was a water-powered mechanical device used for pounding rice. In some TV dramas and movies, you may have seen the large water-powered mills in water mills, which are also a type of water-powered mills.
 
2. The water wheel, also known as the Kongming wheel, is the oldest agricultural irrigation tool in China. It is a remarkable achievement of labor skills created by our ancestors in the process of conquering the world, and it is a precious historical and cultural heritage. It is said that the prototype was created during the reign of Emperor Ling of the Han Dynasty by Hua Lan, and it was improved and perfected by Kongming during the Three Kingdoms period. It was then widely used in agricultural irrigation in Shu State, and it has a history of over 1700 years since the Sui and Tang dynasties.
 
3. In daily life, water turbines are widely used in agricultural irrigation, hydroelectric power stations, and other water conservancy projects. Students with the conditions can also make a simple water wheel in their spare time, observe the differences between it and our experimental device, and what are the disadvantages? How can we better improve it? While cultivating our ability to do things by ourselves, it helps us better understand the principle of the rotation of the small water wheel.43
