Class V SCI

1.   Water

Ø  Helps in our brain function and cleanses our body of toxins

Ø  Helps in digestion

Ø  Helps in keeping our cells hydrated

2.  Vitamins

Ø  Keeps away diseases and keeps you healthy

3.  Protein

Ø  Builds various structures including bones, muscles, skin, and teeth.

4.  Fats

Ø  Helps in absorption of other nutrients

Ø  Improves muscle movement

5.  Minerals

Ø  Builds strong bones and teeth, and maintain healthy blood pressure- Calcium

Ø  Helps in healing process and protects against diseases- Zinc

Ø  Helps in creation of red blood cells- Iron

6.  Carbohydrates

•            Provides energy to brain and body 

1. The wind current turns the turbine.

2. The turning of turbine spins the generator.

3. The generator produces the electricity.

4. The electricity is then distributed to consumers.

Ø  The sun hits the solar panel

Ø  Photovoltaic cell in solar panel captures the light energy

Ø  The light energy is then converted into electrical energy

Ø  The electrical energy is either used directly or stored in a battery for later use

Renewable Energy

Ø  Energy that never depletes (runs out) or can be replaced (replenished) naturally.

Ø  Comes from natural sources like wind, water and solar.

Non-renewable Energy

Ø  Energy that depletes (runs out) due to overuse.

Ø  Comes from fossil fuels like coil, oil (petrol, diesel), and natural gas.

Green Energy

Ø  Environment-friendly and renewable energy (Energy that can pose minimal impact on nature).

Clean Energy

Ø  Energy that does not pollute air (does not produce Greenhouse gasses) and environment.

1. Generation at the power plant

• Electricity is generated at the power plant using hydro, wind, solar, or other sources.

2. Step-up transformer

• The electricity then goes to a step-up transformer, which increases the voltage that allows electricity to travel long distances with less energy loss.

3. Transmission lines

• The high-voltage electricity travels through transmission lines—the tall power lines you see along highways.

4. Step-down transformer

• Near the area of use, electricity passes through a step-down transformer that reduces the voltage to a safe level for homes and businesses.

5. Distribution lines

• Electricity flows through distribution lines (smaller poles and cables) that deliver it to houses, schools, factories, and offices.

6. Inside the consumer’s building

• Electricity enters your home through a meter, which measures how much electricity you use.

• From the meter, it goes to circuit breakers and sockets, so it can safely power appliances and lights.
