The image shows a science worksheet titled
"Is It Magnetic?" designed for students to predict and test whether various objects are attracted to a magnet. The worksheet includes two columns:
Prediction (where students guess if an object is magnetic) and
Test Result (where they record the actual outcome after testing with a magnet).
Objects Listed:
1.
Fork
2.
Knife
3.
Spoon
4.
Copper coin
5.
Silver coin

Step-by-Step Solution & Explanation:
We need to determine which of these objects are magnetic based on their material composition.
#### 1.
Fork, Knife, Spoon
- These are typically made of
stainless steel, but not all stainless steel is magnetic.
- However, many common kitchen utensils (especially older or lower-grade ones) are made from
ferromagnetic stainless steel (like 430 series), which
is attracted to magnets.
-
Prediction: Likely magnetic.
-
Test Result: Usually
attracted to a magnet.
>
✔ Magnetic — Yes (most commonly).
#### 2.
Copper Coin
- Copper is
not magnetic.
- Even though it may have other metals mixed in (like zinc in some coins), pure copper or copper-based alloys are
non-magnetic.
- Example: U.S. pennies (post-1982) are mostly zinc with a copper coating — still
non-magnetic.
-
Prediction: Not magnetic.
-
Test Result:
Not attracted to magnet.
>
✘ Magnetic — No.
#### 3.
Silver Coin
- Silver is also
not magnetic.
- Pure silver or silver-plated items do not respond to magnets.
- Some coins may contain small amounts of iron or nickel, but genuine silver coins (e.g., U.S. quarters, dimes, etc.) are
non-magnetic.
-
Prediction: Not magnetic.
-
Test Result:
Not attracted to magnet.
>
✘ Magnetic — No.

Final Answers:
| Object | Prediction | Test Result |
|--------------|----------------|-------------|
| Fork | Magnetic | Attracted |
| Knife | Magnetic | Attracted |
| Spoon | Magnetic | Attracted |
| Copper coin | Not magnetic | Not attracted |
| Silver coin | Not magnetic | Not attracted |
---
Summary:
-
Magnetic objects: Fork, knife, spoon (if made of ferromagnetic metal).
-
Non-magnetic objects: Copper coin, silver coin.
✔ Key Concept: Only certain metals like
iron, nickel, cobalt, and some of their alloys are magnetic. Most common household metals like
copper, silver, aluminum, gold are
not magnetic.
This activity helps students understand the
properties of materials and how to test them using scientific methods.
Parent Tip: Review the logic above to help your child master the concept of magnet worksheet.
