Ohmygod I'm so tired. But I have to finish this or I won't let myself sleep. (:
So I've decided to do my SRP on if different brands of popcorn leave different amounts of unpopped kernels when microwaved. Ms Zhang kept going on about how we should pick something we like doing and I love food and popcorn so yup. And I got my ideas from here.
EXPERIMENT
Aim: To find whether different brands of popcorn leave different amounts of unpopped kernels.
Hypothesis: Different brands of popcorn will leave different amounts of unpopped kernels.
Equipment: 3 different brands of popcorn packets (actually I don't even know if there are 3 different brands but i'll find out soon), a microwave,
Method:
1. Collect and set up the equipment.
2. Measure popcorn kernels before popping.
3. Place one brand of popcorn in the microwave and microwave for the required amount of time on the packet.
4. Count and measure the number of unpopped kernels for the brand and record results.
5. Repeat steps 2, 3 and 4 for the various other brands of popcorn.
6. Repeat experiment 5 times. (i just realised how much popcorn i'll have to buy)
7. Compare and analyse results.
Yeahh that's what i got up to so far. I'll be analysing how the popcorn actually pops and how the different brands are different from each other, history of popcorn, what the difference in volume is for the kernels and how the factors influence it etc. Wow it sounds kind of technical, I'm not sure if i can pull this off. i want popcorn.

Varying variables.
I forgot about the variables part... okay here it is Ms Zhang.
*Can people taste the difference between regular and low fat foods. Um. The independent variable would be the regular and the low fat food because that obviously doesn't change. Right? And the dependent variable is the different people used in the experiment because everyone has different tastes so the results could vary.
*Water vs energy drinks in exercising. With this one, the independent variable would be the water because water only comes in one form, H2O. The dependent variables are the quantity of the drinks, the brand of energy drinks and the types of exercise that the people are required to perform because different sports and exercises require different energy levels etc.
*Comparing how different types of balls bounce and determining what the factors are that contribute to this difference. independant variables would be... actually I can't think of any. I guess, it's the types of balls used. Dependent variables include the factors which contribute to the difference, such as the surface on which the ball is bounced, what type of ball is used and the height from which it was bounced.
*Do different brands of popcorn leave different amounts of unpopped kernels? independant variables is the type of popcorn used. Omg i am so bad at this LOL. Am I allowed to say LOL in a science blog? Meh. Dependent variables are the time allowed for the popcorn to pop in the microwave and the different brands used.
*How do differences in surfaces affect the adhesion of tape. Independant variables is the tape which remains constant throughout the experiment. Dependent variables are the different surfaces used.
*Is coloured or black and white text more easily remembered. independent variables are the colour of the text and dependent variables are the person trying to remember the text because everyone's brain works differently. And I guess the font matters too.

ideal ideas.
So during the week, i actually racked my brain and tried to come up with some ideas for my SRP. These are the following ideas that I'm considering...
*Can people taste the difference between normal and low fat foods.
*Water vs energy drinks in exercising
*Comparing how different types of balls bounce and determining what the factors are that contribute to this difference.
*Do different brands of popcorn leave different amounts of unpopped kernels?
*How do differences in surfaces affect the adhesion of tape.
*Is coloured or black and white text more easily remembered.
So yeah guys feel free to comment and leave ideas on which one i should pick. I think I'm liking the popcorn one at the moment, I'm getting cravings now. Better start doing my research. Bye kids!
