Data Analysis

Data Analysis. In my science class we had to investigate how the geld of borax affects the spread of polyvinyl acetate gumwood. My teacher (Mr Pillay) invest our class into teammates and my spouse was Jermaine. There were two outliers, which we had to cross out because they do non run across with the rest of the results, this could take for occurred because we may have both measure it for too long, or they may have tried and dependable it an unequal sum of times.

We whence, spill overed 50ml of PVA glue into the Glass Measuring Beaker ready to begin the pratical. 3.

After this procedure I then had to stir the PVA glue and Borax solution unneurotic utilize our two fingers, for stock-still long we thought was correct. * We should have used a timer and timed each stirring to move over the time much accurate; because the longer we stirred it together the thicker th e substance and we could have also used a gl! ass stirring rod cell because the borax was sticking to our fingers therefore fetching some of the borax away and make the results uneven. 5. The next step we took was to pour the slime through a plastic cup that had no bottom which would let the slime through and onto the plastic tray underneath. By using the plastic cup, we do the slime sit in the centre of the tray which made our results more accurate. * We only used the fold going...If you want to get a full essay, order it on our website: BestEssayCheap.com
