Finished!

I have now completed all my trials for all my liquids and have gone ahead to do my report, which is now printed and finished. I was happy with the results and how my experiment turned out, there were some improvements that could be made, but overall, it was pretty good.

I decided, when doing the trials for one of the liquids is that the results weren't all that similar, and maybe I might have to put in more trials, so I made it that I have to do 5 trials for each liquid, so the final table and graph will have a couple of extra columns to fit in that adjustment.

I did a trial run of the experiment to see if it would work or not and I realised that the marble was a little big for the tube. So instead, I found cermic pie weights which are about half the size of a marble. That worked well in water. I am going to tie the tube to a metre ruler to keep the tube straight and then put it onto a slope and then I'll do the actual experiment from there. I tied rubber bands around the tube to the ruler, amrking off the start and finish point- the overall distance that the ball has to travel for each trial is 60 cm.

Starting the Experiment

I have bought all the equipment I need for the experiment. I have plastic tubing, a plastic cap to seal one end of
the tube, a marble, a stopwatch and a variety of liquids.
So now, my next step is to start the experiment. It should be very straight forward and shouldn't take too much time. Straight from my average results, I'll create a column graph based on the average results and then draw a conclusion based on the results. All this information will then be written up into the final report.

So, in my previous post, I posted a mind map of my final idea- viscosity of liquids. From this, I mentioned that the dependent variable is the time taken for the marble to roll through a liquid within a test tube. This time recorded will be an indicator to the viscosity to each liquid, as the faster the marble rolls through the liquid, the less viscous the liquid is. In this case, I will create a table for my results, which will look somewhat like this:

With each trial, I will add the results, and find an average, which I will then create a graph to show my findings. Finding the average provides more reilable results.

Mind Map- Viscosity of Liquids

Absolute Final Idea!

I have now come to my absoulte final idea. I will definitely be ivestigating the viscosity of certain liquids found in the kitchen. These could include honey, canola oil, wines, water, vinegar, yoghurt, egg whites, thickened cream and many more.
I am using this website https://www.planetseed.com/node/19124 as a reference on how to conduct this experiment and also for ideas.
