Grade 3 Sheet 4 focuses on where electricity comes from and how to stay safe around it. Grade 3 learners complete nine fill-in-the-blank sentences about power plants, batteries, outlets, water, insulation, and solar cells. They then match batteries, power plants, solar panels, and frayed cords to the right job or warning. The sheet combines physical science with practical safety rules so Grade 3 students leave with real, useful knowledge about the electricity in their daily lives.

Electricity and Magnetism
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Large buildings where electricity is made for many homes are called power plants.
2. A small portable power source used in flashlights is a battery.
3. You should never put metal objects into a wall outlet because it is very dangerous.
4. Keep electrical cords away from water because this liquid conducts electricity.
5. A wire that carries electricity safely is usually covered in plastic insulation.
6. Electricity can travel from a power plant to homes through long power lines.
7. Solar cells are panels that use sunlight to make electricity.
8. You should never unplug a cord by yanking only the wire.
9. A frayed or damaged cord should be not used in your home.
