Getting nowhere with my experiment. So I booked a session with Ms Tan and together we discussed my experiment. A few of the more important things Ms Tan pointed out:
1. I said 'normal plastic bag' when actually referring to the sandwich plastic bag. Ms Tan corrected me as normal to her was the NTUC shopping bag. Everyone has different interpretation of things, so terms used have to be very specific.
2. There are different plastic grades. Maybe I can expand on this.
3. What am I testing for by poking a pencil through a bag? Is it the durability of the bag?
4. I need to set constant variables for my experiment. E.g., size of plastic bag, amount of water initially, amount of time the pencil is poked into the bag
5. May want to consider using skewers instead of pencils because they are smaller in size
