Electrical Grid

The sun helps to make the electricity we use.

• No

• Yes

Answer explanation

Yes, the sun is a primary source of energy for solar power, which is converted into electricity. Therefore, it plays a crucial role in generating the electricity we use.

Electricity can be made by the wind.

• No

• Yes

• no one can know

Answer explanation

Yes, electricity can be generated by wind through wind turbines, which convert kinetic energy from wind into electrical energy.

How is the sun related to the power grid?

• Energy starts with the sun

• The sun doesn't really do much for the power grid

Answer explanation

The correct answer, 'Energy starts with the sun', highlights that solar energy is a primary source for many power grids. Solar power systems convert sunlight into electricity, directly linking the sun to energy generation.

Turbines can help create electricity?

• False

• True

• no one can know

Answer explanation

True. Turbines convert kinetic energy from wind, water, or steam into mechanical energy, which is then used to generate electricity. This process is fundamental in renewable energy production.

The metal copper can conduct share electricity.

• No

• sometimes

• Yes

• Only if it wants to.

Answer explanation

Copper is a metal known for its excellent electrical conductivity. Therefore, it can conduct electricity effectively, making the correct answer 'Yes'.

What can transport or share electricity from place to place

• a car

• power lines

Answer explanation

Power lines are specifically designed to transport electricity over long distances, making them the correct choice. A car does not share or transport electricity in the same way.

What is the electrical grid?

• a way to create and share electrictiy

• a way to share care and love to others

Answer explanation

The electrical grid is a system that generates, transmits, and distributes electricity to consumers. It enables the creation and sharing of electricity, making the first answer choice correct.

Where can electricity be made?

• solar factory

• Candy factory

Answer explanation

Electricity can be made in a solar factory, where solar panels convert sunlight into electrical energy. A candy factory, on the other hand, primarily produces sweets and does not generate electricity.

What are the differences between a windmill and a dam?

• One uses wind the other uses water

• One uses water and the other uses only sunshine

• One uses wind and the other uses only wires

Answer explanation

A windmill harnesses wind energy to generate power, while a dam utilizes water flow to produce energy. Thus, the correct choice highlights that one uses wind and the other uses water.

What do dams use to make electricity?

• Wind

• sun

• water

• kindness

Answer explanation

Dams generate electricity by using the energy of moving water. As water flows through the dam, it turns turbines that convert this kinetic energy into electrical energy, making water the correct answer.
