Step-by-step solution for: Charge it! | 4th Grade Reading Comprehension Worksheet
Thank you for sharing this educational worksheet titled “Charge It!” from Cross-Curricular Focus: Physical Science. Since I cannot view images directly, I’ll base my response on the text you’ve provided — which appears to be the entire content of the worksheet.
This worksheet teaches students about static electricity, conductors, and insulators through a short reading passage and five comprehension questions.
---
---
## Question 1: What are two materials that are good conductors of electricity?
Answer:
Copper and gold (or silver, aluminum — any two from the passage).
Explanation:
The passage says: *“We call materials that electric current flows through easily conductors. Water is also a good conductor of electricity. That’s why electrical charges can travel through water... Metals such as copper, gold, silver, and aluminum...”*
So, any two metals listed (copper, gold, silver, aluminum) are correct. Water is also mentioned, but since it’s not a metal, you may want to stick with metals unless instructed otherwise.
---
## Question 2: How is static electricity different from electric current?
Answer:
Static electricity builds up on certain materials and doesn’t flow continuously, while electric current flows steadily through conductors like metals or water.
Explanation:
The passage explains: *“Static electricity builds up on certain materials… This creates an electric current.”* Wait — actually, let’s clarify: Static electricity is a build-up of charge that stays in one place until discharged (like a shock), whereas electric current is the continuous flow of electrons through a conductor (like in wires or circuits). The passage says: *“Electric current travels very easily through metals like copper, gold, silver, and aluminum.”* So static = stationary charge; current = moving charge.
✔ Better answer:
> Static electricity is a buildup of electric charge on the surface of an object that does not move, while electric current is the continuous flow of electric charge through a conductor.

## Question 3: What could happen if the rubber coating on a power cord is damaged?
Answer:
The exposed wire could cause an electric shock or short circuit because the insulating layer is no longer protecting against contact with the conductor inside.
Explanation:
The passage says: *“Rubber coating that you see on electrical cords covers the metal. The electric current stays inside the cord so we do not get shocked…”* If the rubber is damaged, the metal wire inside is exposed, which means:
- You could touch the live wire and get shocked.
- The wire could touch something else (like metal or water) and cause a short circuit or fire.
---
## Question 4: Is water a conductor or an insulator?
Answer:
Water is a conductor.
Explanation:
The passage clearly states: *“Water is also a good conductor of electricity.”* And adds: *“That’s why electrical charges can travel through water.”* Even though pure water is a poor conductor, tap water or natural water contains dissolved minerals that make it conductive — and that’s what the passage refers to.
---
## Question 5: In your own words, explain the difference between a conductor and an insulator.
Answer (in your own words):
A conductor lets electricity flow through it easily — like metals or water. An insulator blocks or slows down the flow of electricity — like rubber, plastic, or glass. Conductors are used to carry electricity where we need it, while insulators protect us by keeping electricity from going where it shouldn’t.
Explanation:
From the passage:
> *“Conductors allow electricity to pass through them. Insulators do not allow electric current to pass through them.”*
So, the key idea is:
- Conductor = electricity flows easily → useful for wires, circuits.
- Insulator = electricity does NOT flow easily → useful for safety coatings, handles, etc.
---
- Always go back to the passage to find answers — it’s designed to be self-contained.
- Use full sentences when answering, especially for #5.
- For science questions, use precise vocabulary (e.g., “flow,” “build-up,” “exposed,” “short circuit”).

✔ Completed Worksheet Answers Summary:
1. Copper and gold (or any two from: copper, gold, silver, aluminum)
2. Static electricity is a buildup of charge that doesn’t move, while electric current is a continuous flow of charge through a conductor.
3. If the rubber coating is damaged, the metal wire inside could be exposed, leading to electric shock or short circuit.
4. Water is a conductor.
5. A conductor allows electricity to flow through it easily (like metal), while an insulator stops or slows the flow (like rubber or plastic).
