2. Question
How can you make a water
compass?
Do you know how to make a
water compass?
We will tell you.
3. Prediction
We think we will be able to
make a water compass.
It will point north.
4. Plan (Steps)
Fill a cup with water.
Place an iron needle on your cork.
Tape the needle on the cork so it
doesn’t fall off.
Stroke the needle about 15 times
on your magnet (stroke from top
to bottom in one direction)
Put the cork with the needle in
the water.
Mark the plate with N, S. E and W.
Turn the plate so the needle is
pointing to the N for north.
5. Results
Our results show that the
front of the needle points
north and the back of the
needle points south.
6. Conclusion
I claim that this compass works.
I can prove that by showing a picture of
it.
Our results show that the needle points
north.
I found out that it is important to tape
the needle on the cork.
You can use this in real life, because it
tells you where north, south, east, and
west is.
Next time I would change the plate into
a deeper one.
I still wonder if the oil would work
better than the water.
7. Real world uses

You can use this in real life
