The method below is my final method, I have made a couple of changes here and there from my draft method to make sure it executed the experiment very well and also referred back to page 64 in our Science Booklets to read over my Experiment on "Detergent Pollution" that I designed previously. This helped me a lot , I was successfully able to complete my final Method.
I also found this site very useful in relation to constructing and guiding me to write up an appropriate method for my experiment.
I also remember in class Mr.Ng telling us that when we construct methods is that we should start ever step with a verb, for e.g 'Press, Take, Measure'.
Method
- Make sure you have all your equipment prepared to use
- Prepare data sheet
- Choose one bag of popcorn and remove from plastic packet and dispose in bin.
- Unfold popcorn bag and place flat down on microwave plate.
- Close microwave door.
- Set timer to 2 minutes and press start.
- Wait until times goes off and open microwave door.
- Time 10 minutes from when you open the microwave door using a timer or stopwatch.
- Once this time is up , Take out popcorn bag from microwave and open the bag.
- Sort the popcorn individually into either the small bowl for the un-popped or the big bowl for the popped popcorn.
- Count how many un-popped kernels and popped kernel there are and record into the first table (table 1)
- Repeat steps 3-11 for the remaining bags of popcorn
- Calculate the average number of popped, un-popped, and total kernels for each brand of popcorn by adding the data recorded for that brand and record in second table (table 2), after all bags are popped and recorded.
- Divide the number of popped kernels by the number of total kernels to find the percentage of popped kernels for each brand and record results in the second table (table 2) and graph results in column graph and stacked column graph like the ones listed below.
- Compare Results.
