Educational Animations

An animation is a fast sequence of pictures of an object at different positions. The fast sequence tricks our eyes and the object seems moving.

Shown below is an animated logo of EduMation.

Sometimes, animations are used to help explain and illustrate theories, concepts, procedures or any information that may be difficult to comprehend by just explaining in text or verbally.
These are known as educational animations.

Nowadays, animations are made with computer software such as Flash, SwishMax, Photoshop, Swift3D, 3dsMax and many others.
Well-designed animations may help students learn faster and easier. They are also excellent aid to teachers when it comes to explaining difficult subjects. The difficulty of subjects may arise due to the involvement of mathematics or imagination. For instance, the flow of electric current is invisible. The operation of electric circuits is difficult for students to understand at the beginning. With the aid of computer animations, learning and teaching may become easier, faster and amusing!

The animated electrical circuit shown below helped many trainees at Bahrain Training Institute to understand the circuit faster than reading two pages about its operation.

Relay

A traditional relay is an electro-mechanical switch that opens and closes a set of contacts under the control of another electrical or electronic circuit that is known as the control circuit.

Relays are found everywhere in today’s modern life. They exist in most of our modern home appliances: microwave ovens, washing machines, TV’s, VCR’s and cassette recorders.

The relays switch on the turn table, lamp and buzzer in the microwave oven. Relays are also used in the washing machine to turn on electric motors and buzzers. Many relays are used in cars as well to turn on the horn, windows, motors and lights. These are commercial applications of the relay but the number and applications of relays in the industry are countless where they play a vital role.

The main function of a relay is to isolate high voltage/current circuits from control circuits or operator for different reasons: safety, protection and comfort of operator.

There are many applications of the relay. Here are only some:

• Domestic: home appliances, security systems

• Commercial: cars, elevators, lighting

• Industrial: automation, motor control, heating, lighting, hoisting, traction
  

The relay was invented by Joseph Henry in 1835 but it is still used widely nowadays. This invention led to a successful demonstration of the electrical telegraph in 1837 by Samuel Morse and Charles Wheatstone.

Lemon Experiment

By Mustafa Daif
Founder- EduMation

Objective
· To generate 3.5V from a series connection of 4 potatoes or 4 lemons
· To light a small Light Emitting Diode (LED)
Components
· 4 fresh lemons or potatoes
· 4 galvanized nails (steel nail coated with zinc)
· 4 pennies (or any piece of copper)
· 5 pieces of wire
· Calculator
· Small LED or a small lamp from any baby toy

Brief Description
Any battery consists of these three: positive terminal, negative terminal and an acid.
A lemon contains citric acid. The steel nail (ZINC) is the negative (-) terminal and the penny (COPPER) is the positive terminal (-).
The chemical reaction inside the lemon causes the electrons to move from the zinc to the copper.

Procedure
1. In each lemon, insert a penny and a steel nail at the extreme sides of the lemon.
2. Connect a wire between the nail of lemon 1 to the penny of lemon 2, the nail of lemon 2 to the penny of lemon 3 and the nail of lemon 3 to the penny of lemon 4. This is called a series connection.
