Figure 5 Some histograms of the colour charts of the movements
As can be observed, the mosaic charts show immediately if there
are differences between the movements, as well as if there are
patterns. The differences in the colours make it easier to see the
degree, direction, and timing of the sensor data. The histogram
charts show both the frequency of the movements (i.e. how many
times the sensor was moved in a specific direction), while the
value gives the intensity of that movement. One observation
made by Grace and Ryley was that tennis has a greater variety
of movements than cricket, while cricket had more distinct
groupings than tennis. a graph, so we could see if our predictions were correct. We
Both Ryley and Grace described the experience in their own
words. I really enjoyed working with another person.
Grace describes what she noticed: doing their science investigations. While the main driver for these
tested jumping on a trampoline, tennis, cricket, bike riding,
horse riding, and tested to see which directions and movements
were represented by different colours. We made graphs for
each activity, and compared them with the graphs for the other
activities. We wanted to see and measure the differences. For
example, is there more red, green or blue, when you compare
tennis with cricket, as one is more side to side, while the other is
more up and down.
In summary, both the junior and senior Capstone children enjoyed
activities was the NSW Young Scientist Awards entry, they all
We used the app Apar on an android ‚phone. We used the
app to record movements, and then discovered which colour
represented each movement. The activities we used to see
these movements were tennis, cricket, horse riding and bike
riding. We learned that we could make different types of colour
patterns. Then we put the colour patterns onto graphs to see
if our calculations of movement and colour were correct. Our
predictions were correct. I really enjoyed this experiment!
liked the idea of finding a question, developing an experiment
to answer the question, and then understanding the results and
explaining them to others. The Capstone Kids would like to thank
both the STANSW for this opportunity to publish another story on
their science explorations, and the support of the teaching staff
at Lane Cove Public School, for their encouragement / mentoring
of the students in science investigations, and for use of the
