Testing the results:
Now, for testing the results from my experiment, I was thinking of creating three tables (shown below) highlighting the three main points. The first table of course, will record the water evaporation. So 1column could say water level in ml, the second column could say: water level height in cm, the third could say: amount of water evaporated in ml and the fourth column could say: water height evaporated in cm. I think that covers all the aspects of water evaporation.
For table 2, the first column could record the ph level of all 4 liquids, the second column could record the chlorine level of all liquids, the 3rd column could record the total alkalinity of the different liquids and the fourth column could record the stabilizer level.
For the third table, this would record the colour and appearance of the liquids in the four different measuring cups. I was thinking that the first column would record the colour and the second column would record the appearance, eg bubbly, murky etc. Before starting the experiment, I thought that all liquids would have the same colour and appearance, but now, after setting the experiment up and observing it, I have realised that this is not the case. I think that this would be a very interesting table to have.
I was thinking to have the tables drawn once a week as a sort of summary for all the records and observations for the week, and then every 2 days to just record the results normally, not in a table.
This is what table 1 would look like (measuring water evaporation)
This is what table 2 would look like (measuring the ph,chlorine, alkalinity and stabiliser content of all liquids)
This is what table 3 would look like (recording colour and appearance) :
Okay, now for the results from day 1!
Water evaporation:
Well since it is the first day there had been no water evaporation. All the liquids in the glasses are the same height they were to start off with:
Measuring cup 1-plain water: current height in ml: 250 ml
Current height in cm: 7.5 cm
Current water evaporation loss in ml: 0ml
Current water evaporation loss in cm/mm: 0 cm
NOTE: the measurements for today are all the same for measuring cups 2, 3 and 4 as well.
Ph, chlorine, alkalinity and stabiliser content:
Measuring cup 1- plain water: (i will include pictures of all the strips in the next blog, as the wont post in this one!)
Ph level: 7.2 (this is in the ok range-this range lasts from 7.2 to 7.8)
Chlorine level: 0 (this is in the low range- this range lasts from 0 to 0.5)
Alkalinity: 80 ppm (this is in the ok range- this range lasts from 80 to 120)
Stabilizer: 0 ppm (this is low, there is only one figure)
Measuring cup 2- chlorinated water: Ph level: 6.8 (this is in the low range- this range lasts from 6.2 to 6.8)
Chlorine level: 1 (this is in the pool ok range- this range lasts from 1-2.5)
Alkalinity: 0 ppm (this is in the low range- this range lasts from 0-40)
Stabilizer: 0 ppm (this is low, there is only 1 figure)
Measuring cup 3- chlorinated water with liquid pool cover Ph level: 6.2 (this is in the low range- this range lasts from 6.2 to 6.8)
Chlorine level: 1 (this is in the pool ok range- this range lasts from 1-2.5)
Alkalinity: 40 ppm (this is in the low range- this range lasts from 0 to 40)
Stabilizer: 0 ppm (this is low, there is only 1 figure)
Measuring cup 4- chlorinated water with solid pool cover
The measurements for this liquid are exactly the same as the ones listed for measuring cup 2, as they both contain the same chlorinated water.
Ph level: 6.8 (this is in the low range- this range lasts from 6.2 to 6.8)
Chlorine level: 1 (this is in the pool ok range- this range lasts from 1-2.5)
Alkalinity: 0 ppm (this is in the low range- this range lasts from 0-40)
Stabilizer: 0 ppm (this is low, there is only 1 figure)
Colour and appearance:
Measuring cup 1- plain water: the colour is clear and the appearance is quite bubbly. There are tiny bubbles everywhere in the liquid.
Measuring cup 2- chlorinated water: the colour is clear, and the appearance is quite clean and clear as well. There are no bubbles like in glass 1and it is completely clear.
Measuring cup 3- chlorinated water with liquid pool cover: the colour is opaque and the appearance is murky. The liquid pool cover has risen to the top and has a length of approximately half a cm. It is translucent and murky white.
Measuring cup 4- chlorinated water with solid pool cover: the colour and appearance are exactly the same as measuring cup 2.
ps: i will post the pictures of all of the AQUA CHECK strips for all 4 measuring cups in the next blog (they wont fit here!)
