Conclusion

1) As Clarissa was told to apply as much force as she could to the blu-tac on the wall for 10s, she might have gotten tired after one round of pushing the blu-tac against the wall. In order for it to be a fair test, we decided no to switch the person who was pushing the blu-tac. So, perhaps after she pushed the blu-tac against the ceramic wall during the 2nd round, the effort she applied to the other surfaces might not have had been equivalent to that of the ceramic wall during the 2nd and 3rd rounds. Thus, the test might not have had been quite reliable at this point.

2) For some of the surfaces such as the tiled wall, there was a little curb jutting out from the bottom of the wall. Hence, our measurement of one metre from the ground might not have had been as accurate here.

3) When we cleaned the surfaces, some of the fibre from the toilet paper got stuck onto the surfaces, causing less friction between them and the Blu-tac. However, as this was done to all the surfaces, we assumed that it was far

4) When Clarissa pushed the blu-tac against the wall, the force would have caused the blu-tac to change its shape. And as we could not measure the exact amount of force to be applied on the blu-tac, the shape of each blu-tac was different. We could not help this from happening although it does contribute to the accuracy of our results.

Updated Procedure

1) Blu-tac was cut into 12 pieces measuring 0.5g

2) The Blue-tac was them moulded into squares measuring 1cm x 1cm x 0.2cm

3) 12 strands of string, each measuring 32cm was cut from the roll of string

4) The pieces of Blu-tac were then measured again and marked at their midpoint of 0.5cm

5) Each piece of string was stuck onto a slab of blu-tac, exactly in its middle.

6) the strands of string were then mesured again( now measuring 31cm each) and were marked at the 30cm spot

7) Strings were tied onto the weight holder, their knots resting at the marked spot of 30 cm. (Now, each piece of string measures exactly 30cm)

8) A weight of 50g was fitted onto the weight holder

9) The blu-tac (complete with the string and weight holder) was brought to the first venue of the experiment-the tile wall

10) Using the one metre ruler, we measured and positioned the Blu-tac one metre away from the ground

11) Using some wet tissue, we wiped the area around the one metre mark. Following that, we used some toilet paper to wipe it dry. Thus make it grease-free

12) Using as much as force as she could, Clarissa pushed the Blu-tac while Deborah started the stopwatch as soon as Clarissa started exerting force on the Blu-tac

13) This was done for ten seconds and soon as Clarissa stopped pressing the Blu-tac, Deborah, holding the two stopwatch, pressed the start button on the other stopwatch to calculate the time taken for the Blu-tac to drop.

14) The timing was then recorded

15) Step 9-13 were then repeated for the three other surfaces-the tile wall, lift door and the glass door

16) Process was repeated three times (three rounds)

IMPORTANT!!!ATTENTION NEEDED@ONCE!!!

Umm... Guys? WE really need to do ALOT of touching up on our Science Project. I reckon that it has been a long time since any of us did anything and we've probably forgotten about this altogether. WE haven't even done the form that We were supposed to fill in on the e-learn portal properly.Remember the one which WE did at the last minute?We wrote it out instead of typing it. Ms Phua wasn't too happy about it. WE are the only group that submitted it handwritten. I really want all of us to do this project well.

Please,

can each of you all try to go to e-learn whenever you are free and try to do up your own piece of the 2010 Report Template?THIS IS A MUST!

I'll give you the data soon. Need to go find it...

Meeting for Presentation

Hey guys:) we really have to meet up to discuss the presentation details.. So text each other to see when we are all free.. :) ok, thanks guys:)

I reckon that it would be rather difficult to present our findings in a bar chart, because there are those milliseconds that we have to record down too.

WE can't possibly go and write down all those minute details.

Or should WE just roughly gauge and round the timings up to the nearest second?

What do you all think?
