WONDER OF SCIENCE

Introduction

Have you heard of global warming?

Well it has affected the oceans by making it unsuitable for its aquatic inhabitants.

Introduction

Aim

To determine the heat capacity of air, water and saltwater.

Hypothesis

Water balloon - will stay intact the longest

Saltwater balloon - the second longest

Air - the least longest

Method

First the materials were organised.

Experiment

Method continued

Then each balloon was placed over a flame and timed until it popped.

Method continued

Experiment Completion

Experiment

Results

Average time taken for balloons to pop:

Air balloon - 1.36 seconds

Water balloon - 2.11 seconds

Saltwater balloon - 5.23 seconds

Results

What was found

The results from the experiment refuted the hypothesis as they differed from what was expected.

Discussion

Errors and Improvements

Is the research incorrect?

This small experiment can not be compared to scientifically supported research performed by professional scientists.

Conclusion

What does this mean for the oceans?

Water has a much higher heat capacity than air, meaning the oceans can absorb larger amounts of heat energy with only a slight increase in temperature.
