This easy-level worksheet has students fix sentence errors, fill in blanks, and write short answers to practice electricity and circuits skills.
It includes 9 questions across 3 sections for focused practice.
Style:
Electricity and Circuits
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Static electricity happens when protons move from one object to another by rubbing.
Rewrite: Static electricity happens when electrons move from one object to another by rubbing, causing one object to become negatively charged and the other positively charged.
2. Fix the sentence:
A switch must stay closed for a circuit to stop working and turn off a light.
Rewrite: A switch must be opened to break the circuit and turn off a light; closing the switch allows electricity to flow again.
3. Fix the sentence:
In a parallel circuit, if one light bulb burns out, all the other bulbs go out too.
Rewrite: In a parallel circuit, if one light bulb burns out, the other bulbs stay on because each bulb has its own separate path for electricity.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. When you shuffle your feet on carpet and then touch a doorknob, you feel a shock from static electricity.
2. Every circuit needs an energy source, wires, and a load such as a bulb or motor.
3. Objects with the same electrical charge repel each other.
4. A battery is a device that stores chemical energy and converts it to electrical energy.
Part C: Short Answer
Answer each question in one or two complete sentences.
1. Why does a balloon stick to a wall after you rub it on your hair?
Rubbing the balloon on your hair transfers electrons to the balloon, giving it a negative charge. The charged balloon attracts the positive charges in the wall, which makes it stick.
2. Describe what happens inside a flashlight when you flip the switch to the ON position.
Flipping the switch closes the circuit, creating a complete path from the battery through the wires to the bulb and back. Electricity flows through the bulb, which converts the electrical energy into light.
