The main challenge today was time management. We didn't have time to go as high as we wanted and this is because of a few factors. Firstly, it took us a long time to find a way of measuring data. We tried other things before like measuring the maximum stretch the barbie would go at each height. The second and biggest factors was communication. We lost a lot of time because we didn't have set roles for each of of the positions for the experiment. Also, when we were on the stairs, it was hard to communicate with the person at the bottom because we couldn't see them (as we had to hold the measuring tape). Another small challenge we had is I accidentally broke the measuring tape and it got all tangled. We gave it to maintenance and it should be repaired soon. We still go through a lot today and I am happy with the amount we achieved. Now we will have to make the calculations and plot our results on a line graph so that we can find the equation of the line that will work at any level.
Below are two of our tests:
