HOW TO : Make a working Wind Turbine (Begginer)

It's the time holidays are ending and finally some students are starting doing their projects. Here's one of the most common project for high schoolers- a working wind turbine. So, take a look at some very simple steps to make a wind turbine.




Material Required:
1.A Bicycle dynamo (can easily get from a cycle shop)
2.Stand
3.Rotor
4.Bulb
5.Connecting Wires


Procedure:
1.Take a cycle dynamo and connect a bulb to it using connecting wires.

Dynamo connected to a bulb.

2.Make a stand about 1 feet in height.
3.Put the dynamo on the top and connect the rotor to it.
4.Finish the project by cleaning the edges an, you are done.

Basic Principle involved - Electro-magnetic Induction:

Basic Principle.

Electromagnetic induction is the production of an electric current across a conductormoving through a magnetic field. It underlies the operation of generators, transformers,induction motors, electric motors, synchronous motors, and solenoids.^[1]

Michael Faraday is generally credited with the discovery of induction in 1831 though it may have been anticipated by the work of Francesco Zantedeschi in 1829.^[2] Around 1830^[3] to 1832^[4] Joseph Henry made a similar discovery, but did not publish his findings until later.

Holidays' Homework - A goodwill or burden?

Today Holidays' Homework has become an integral part of the school curriculum. And why shouldn't it be? Students have almost 2 long months and apparently nothing to do (apart from a lot of hobby classes, coaching and all the stuff). So every time a quest arises, is holidays' homework necessary? Some say yes some say no. Let us take a deeper look.

Afraid?

How students react to Holidays' Homework? 


Students will remain as they were. For them holidays homework is just a burden but the are capable to go with it. They can't protest or start a campaign against all the homework. How they react is never asked, and even if they are, nobody cares. Some are there who like doing all the fancy glitter stuff in their notebooks but for them, one thing- "Holidays are for fun, not for doing homework!"


How teachers react to Holidays' Homework?


Teachers, again, as they are, are standing in front as the pioneers of education. Afterall, they are the ones who build a person and thus build a society.In teachers' view holidays homework gives opportunity to students to do something "creative". But it raises a question- Does creative mean doing fancy charts or making a simple circuit with a small working bulb (for high-schoolers).
Everyone has a view but for teachers holidays' homework is integral and necessary.

How parents react to Holidays' Homework?


Uff! - Similar expressions by parents when they face their wards' homework.
Homework is a bigger burden on parents than it is on students. Printouts,stationary,chart-papers and headache.The holidays' homework for students below class 5 is the holidays' homework for parents and for students above class 5- money. A survey shows, on an average, parents spend 1200 bucks on their children's holidays' homework.

Conclusion


Everyone has their own conclusion, but mine is - Homework should be something that is a mixture of fun and knowledge. It should never act as a burden over students (since they have a lot of it already). And the day students find homework interesting and fun, that day would be a step towards a better education system.
