The Mystery of the Broken Compass

“The compass is broken.”

Adam stared at the red needle.

A few seconds earlier, it had pointed north.

Now it was pointing towards Hariz’s elbow.

Hariz moved his arm.

The needle moved too.

Adam frowned.

“Compasses aren’t supposed to follow people.”

Hariz looked at the small compass in his hand.

“Maybe this one likes me.”

Adam did not laugh.

Their team had only twenty minutes left to finish the school’s Outdoor Science Challenge.

And without a working compass, finding the next checkpoint was going to be difficult.

---

That morning, Year 5 pupils had gathered in the school garden for a STEM activity.

Each team received a simple map, a compass and a clue card.

Their task was to find four checkpoints placed around the school grounds.

At every checkpoint, they had to solve a small science challenge before receiving the next clue.

Their teacher, Mr Daniel, had given them one warning before they started.

“If a tool gives you a strange result, don’t immediately assume the tool is wrong.”

Hariz had whispered to Adam, “What else could be wrong?”

Adam had shrugged.

Now, standing beside a row of hibiscus plants, he remembered those words.

---

The first two checkpoints had been easy.

At the first station, they measured the length of several leaves.

At the second, they identified which materials were attracted to a magnet.

Their next clue said:

Walk north until you reach the large rain tree. Then turn east towards the vegetable garden.

Adam had placed the compass flat on their map.

The needle turned.

Then stopped.

“North is that way,” he said.

They walked several metres.

Hariz checked the compass again.

This time, the needle pointed somewhere else.

“That can’t be right.”

Adam took it.

The needle moved again.

They turned around.

So did the needle.

Hariz sighed.

“I told you. Broken.”

---

They sat at a wooden bench.

Adam turned the compass slowly in his palm.

The red needle continued behaving strangely.

“Should we just guess where north is?” Hariz asked.

“If we guess wrong, we’ll waste more time.”

“We could follow another team.”

“That’s definitely cheating.”

Hariz looked towards the other pupils disappearing around the science garden.

“Then what?”

Adam thought about Mr Daniel’s warning.

A strange result did not automatically mean the tool was broken.

He placed the compass on the bench.

“Let’s test it.”

“Test what?”

“Everything.”

Hariz raised an eyebrow.

“That sounds like a very long experiment.”

“Not everything at once. One thing at a time.”

---

First, Adam checked the compass casing.

There were no cracks.

The needle could move freely.

He placed it flat again.

The red end swung towards Hariz.

Hariz leaned to the other side.

The needle shifted.

Adam froze.

“Do that again.”

“Do what?”

“Move.”

Hariz leaned left.

The needle moved slightly.

He leaned right.

It moved again.

Both boys stared at each other.

Hariz slowly stood up.

The needle turned.

Adam pointed at him.

“You’re doing something.”

“I’m standing.”

“Something you’re carrying.”

Hariz emptied his pockets.

A pencil.

Two coins.

A folded worksheet.

A key.

Nothing unusual.

Adam tested the compass again.

The needle still behaved strangely.

“Your bag.”

Hariz pulled his small sling bag from his shoulder and placed it on the bench.

The compass needle turned towards it.

They both went silent.

---

Adam moved the bag away.

The needle slowly settled.

He moved the bag closer.

The needle turned again.

Hariz’s eyes widened.

“There’s something in my bag.”

They opened it.

Inside were a notebook, a bottle of water and a blue pencil case.

Adam removed the notebook.

Nothing happened.

He removed the bottle.

Still nothing.

Then he lifted the pencil case.

The compass needle followed it.

Hariz stared at the pencil case.

“You cannot be serious.”

Adam brought it closer.

The needle swung sharply.

“Something in here is magnetic.”

They emptied the pencil case onto the bench.

Pencils rolled everywhere.

An eraser fell onto the map.

A ruler landed on Hariz’s shoe.

At the bottom of the pencil case was a small magnetic clasp used to keep its flap closed.

Adam held the compass away from it.

The needle settled.

Hariz brought the pencil case closer.

The needle moved.

They tried it three more times.

The same thing happened every time.

---

“So the compass isn’t broken,” Adam said.

Hariz picked up the pencil case.

“This tiny thing caused all that?”

“It has a magnet.”

Hariz stared at it as though the pencil case had betrayed him.

“My pencil case has been secretly changing north.”

Adam laughed.

“North didn’t change.”

“You know what I mean.”

They moved several metres away from the bench and placed the pencil case inside Hariz’s backpack, well away from the compass.

Adam laid the compass flat.

They waited.

The red needle turned gently and stopped.

He rotated the compass.

The needle returned to the same direction.

Again.

And again.

This time it behaved exactly as expected.

“There,” Adam said. “North.”

Hariz looked towards the large rain tree.

It was almost directly ahead of them.

“We were walking the right way before the pencil case got too close.”

---

They hurried to the rain tree, then turned east towards the vegetable garden.

A bright yellow card hung beside a row of chilli plants.

CHECKPOINT 3

Hariz grabbed it.

“We found it!”

Mr Daniel was standing nearby with a clipboard.

“You took longer than most teams,” he said.

“Our compass broke,” Hariz replied.

Adam shook his head.

“We thought it broke.”

Mr Daniel looked interested.

“What actually happened?”

Hariz held up his pencil case.

“The compass kept pointing towards this.”

“Why?”

“It has a magnetic clasp.”

Mr Daniel nodded.

“And what did you do?”

Adam explained how they had moved one object at a time and watched what happened to the compass.

“So,” Mr Daniel said, “what was your most useful tool?”

Hariz lifted the compass.

“This?”

Mr Daniel smiled.

Adam thought for a moment.

“No. Testing.”

Mr Daniel wrote something on his clipboard.

“That answer earns your team an extra point.”

Hariz grinned.

“Best broken compass ever.”

---

They completed the final checkpoint with three minutes remaining.

Back in class, Mr Daniel asked each team to share one thing they had discovered during the challenge.

Some pupils talked about leaves.

Others talked about magnets or measurements.

When it was Adam and Hariz’s turn, Hariz placed the compass on the teacher’s table.

“This compass caused a mystery.”

Adam placed the pencil case beside it.

The needle moved.

Several pupils gasped.

He pulled the pencil case away.

The needle returned.

Mr Daniel explained that a compass needle is itself a small magnet. Normally, it aligns with Earth’s magnetic field. A nearby magnet can interfere with that reading and pull the needle in another direction.

“So the compass wasn’t lying?” one pupil asked.

“No,” Adam said. “We just weren’t giving it a fair place to work.”

---

Before going home, Adam looked at the compass one last time.

That morning, it had seemed like a simple tool.

A red needle.

A few letters.

Nothing mysterious.

But for ten confusing minutes, it had made two boys question their map, their direction and even the compass itself.

Hariz zipped his pencil case.

“Next time we use a compass, this stays far away.”

Adam nodded.

Then he smiled.

“The funny thing is, the compass wasn’t really broken.”

Hariz looked at him.

“What was?”

Adam picked up their completed challenge card.

“Our first guess.”

Values

• Curiosity — Adam investigates the strange compass reading instead of simply guessing.
• Perseverance — the boys continue testing until they find the cause.
• Critical thinking — they change one factor at a time and compare the results.
