1) Take some blu-tac and weigh it on an electronic weighing scale
2) Measure it and make sure the blu-tac weighs 5 grams and 1cm(width) by 1cm(length)
3) Stick the 1.5kg weight on the blu-tac
4) Let of the 1.5kg weight
5) Measure how long the blu-tac stays on
6) Measure how fast the blu-tac with the 1.5kg weight falls
7) Repeat steps 1-6 three more times for each surface to increase the accuracy of the results
8) Repeat steps 1-7 for all four surfaces

ReplyDeleteI think that you should have posted the Hypothesis,Apparatus and Materials needed and Experimental procedure set-up together as you are just 'lifting from our group's Project Proposal Form anyway.By the way,I thought that Josephine already said that she wanted to post this? Must have more communication in the group:)
ReplyDeleteoh... ok.. i didnt see her post... sorry jo... ill let u guys post it next time...hmmm.... jo alr bought the blu-tac by the way... she called me last night.. i think she only bought 1pack... so yeah... sorry jo... :(
ReplyDeleteoh... yeah... lighter weight.. maybe the weight is too heavy then the blu-tac falls straight away.. but we should try it first and get the specific weights before we actually do the experiment.. so we have to check with ms.phua..
ReplyDeletedo we need step 6? actually why are we looking at the speed of how fast the blu-tac falls? shoudlnt it be only how long the blu-tac will stay on?..
