Looking at data from experiments

One of the benefits of using computer sensors is that you can clearly see the changes that occur in your experiments. Here we show you the results that we obtained in ours.

We'd like you to study them. Our results tell the 'story' of what happened in our investigations. You might like to answer the questions about them. You might even like to tell us the answers! You might like to try some of the experiments suggested. If you can do what we did and get the same result we can't be too far wrong. Our message is that the graphs you obtain from experiments with sensors are rich in data. Compared to manual approaches, there is much to explain, much to query and new opportunities for learning to seize.
