2. What’s this all about?
Our project
‘Could this be a Cool Current?’
came from our study
of ocean currents
junior certificate geography.

3. • The ocean current we
focused on for this project
is the North Atlantic Drift.
• This is the main current
which effects Ireland.
• The North Atlantic Drift is a
warm current.
• It comes from equatorial
region.
• It flows towards the North
Pole and becomes cooler.
• It passes Ireland as it
flows.

4. The icebergs from the North
Pole are melting due to
climate change.
They are causing the
temperature of the
North Atlantic Drift to change.
Our project researches how, why and what is happening and
will happen in the future
due to this change?

5. Why we chose the project
We decided to research the changes to the North Atlantic
Drift if effects the area in which we live.
Also we found water experiments to be very interesting
and we were able to carry out many experiments on a
smaller scale to back up our research.

7. Experiments
Our first experiment:
Our first experiment
was to see how the ratio
of salt to water effects
how hot and cold water
mix together.

8. Apparatus: Beakers, probe, salt, 400ml
water, a kettle and a measuring scales.
Aim: see how the ratio of salt to water
effects how hot and cold water mix
together.

9. Method:
1. We filled one beaker with boiling water
(200ml) and another with cold water (200ml).
2. We added the hot water into the beaker of
cold water and used the probe to measure the
temperatures of both the bottom and the top
of the beaker.
3. We repeated this after several time intervals
and gathered the results.
4. We repeated this experiment with 2g of salt
added to the water

10. Results & Conclusion:
The hot water always rises to the top and
the cold water sinks to the bottom.
When the salt is added the difference in
temperature from the bottom to the top
is greater.

11. This is a diagram of our conclusion

12. Other Experiments:
• We also researched weather reports from
the last 20 years.
• We wanted to show that the weather has
slowly began to cool due to this current.
