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.

Saturation Point

Like I mentioned before, I had these two possible ideas for my experiment, one of them being the viscosity of liquids, as explained in my pervious post, and the other idea is the saturation point of water using different additives, which I will explain in this post.
So this basically is testing how much of a certain additive can I dissolve into water before the water can't possibly hold anymore. This could be done by using the same amount of water, and adding the same amount of different additives each time, or changing the temperature of the water (for example, leaving it in the fridge, or boiling the water) and testing whether the same amount of one additive, which I will use throughout the whole experiment, is able to dissolve into the water, or is the water able to take more or less than the base amount. If so, by how much.

For this experiment, I would need a measuring jug/ cup to measure the water and the additives, different types of additives, for the first experiment, or just one type for the second, and objects that will change the temperature of the water, for example, a stove and a fridge.

I will later on announce my final idea in upcoming posts, and get started on conducting it.

Thickness of Liquids

So one of my ideas mentioned in the pervious post was the thickness of liquids. I was thinking that I could conduct this experiment in two ways. I either use water as a base, and then add materials to the water, for example sugar or cornflour, to see if the dripping rate has changed. In doing this, I would measure how much liquid has dripped into a measuring cup over a period of, say, 10 seconds. This would indicate the thickness, as the thicker a liquid gets, the less it would drip, therefore have a smaller final amount of liquid in the measuring cup after the 10 seconds.

 I also had this other idea where I used different liquids, instead of just water with additives but still testing the thickness of the liquids. For example, I might use honey, fruit nectar, etc...

In order to conduct this experiment, I'd need to use a funnel, with a very small hole so that the liquid doesn't all pour out at the same time, a measuring cup to catch the drops of liquid, and a timer. The thickness of each liquid would be measured one at a time, so I can ensure reliable results by using the same funnel each time. I would also use the same amount of liquid for each test, and the same amount of additives if I was to do the experiment with water as a base.

Okay, so in my previous post, I had come up with my final idea, which was to measure the burning rate of different type of wax candles.
Well, from research and talking to my teacher, I realised that this experiment would be a lot harder than I thought. I have to consider some very small details, which in the larger picture makes a big difference to the result of the experiment. For example, I have to make sure that the wick material is the same within each candle. Now that is pretty hard, considering that I'm not planning on making my own candles, and the candles found in shops don't usually mention the material that the wick is made from... So I guess I have to move onto a different idea...
Luckily enough, I do have some other ideas that I thought of recently, which include the thickness of liquids, or saturation point, which is how much of a certain material I can possibly dissolve into a liquid.
I'm still thinking about how I might conduct these experiments, in terms of materials and all that, but once I have a clearer image of how I'll do things, I'll continue to post my thoughts and process.
