Let's solve the problem step by step based on the image you described. The worksheet is about
magnetic strength, and it shows three magnets (M1, M2, and M3), each holding a different number of paperclips.
Observations from the Image:
-
M1 holds
2 paperclips
-
M2 holds
1 paperclip
-
M3 holds
3 paperclips
All paperclips are the same size and weight, so the number of paperclips a magnet can hold indicates its magnetic strength — more paperclips = stronger magnet.

Now, let’s answer each question:
---
1. Are magnets M1 and M2 the same strengths?
Answer: No
Explanation: M1 holds 2 paperclips, while M2 holds only 1. Since they hold different numbers of paperclips, their magnetic strengths are different.
---
2. Which magnet, M1 or M2, is the strongest?
Answer: M1
Explanation: M1 holds more paperclips (2) than M2 (1), so M1 is stronger.
---
3. If we are testing the strength of a magnet, do all the paperclips have to be the same size? Why?
Answer: Yes, all the paperclips should be the same size.
Why? Because if the paperclips were different sizes or weights, it would be unfair to compare how many each magnet can hold. Using identical paperclips ensures a fair test — the only variable being tested is the magnet's strength.
---
4. Which of the 3 magnets is the strongest?
Answer: M3
Explanation: M3 holds 3 paperclips, which is more than M1 (2) and M2 (1). So, M3 is the strongest magnet.
---
Final Answers:
1.
No
2.
M1
3.
Yes, because using the same size paperclips ensures a fair test.
4.
M3
✔ These answers reflect the scientific method: controlling variables (same paperclips) to fairly test magnetic strength.
