...I am ticked off. (Sorry, but I am, so I guess you can expect a blog that is fuelled with emotions such as frustration and anger. Alos, I really want to use the word that is snyonymous to urinated, but I find it is not appropriate.)
EDIT: If you don't want to read about all this irrelevance to my SRP, I suggest you skip the next two chapters.
Why? Because of technology. It is kind of sad how without technology, we'd just all die. Seriously. I know you (Ms. Zhang) don't care about all of this as it is not strictly SRP related, but I need to vent, so again, sorry. I can just hear your sarcastic 'aww' right now. Oh and just for the record, I'm not ticked off at science. Oh no, I would never be angry at science. I mean, it's just too awesome to get angry at. No, no. Science, I would never be angry at you.
So here's a story that will probably waste two or so minutes of your life, and if I could give it back, I guess I would... but I can't. Anyway, basically, I was all excited at coming home and doing my blog, because science is just so awesome! But then (cue that music they play in movies when something bad happens, you know the one, the DUN DUN DUN)stupid, stupid internet just died. So I waited. And I waited. Then what'd I do? You guessed it. I waited. BUT NOOOOOOOOOOOOOOOOOOO. It still wouldn't work. So I waited...and to my relief it connected and I was like 'YES! FINALLY!'. But NOOOOOOOOOOO. Technology hates me. It decided to disconnect again just as I signed into my blog. So then I waited again and that brings me here. Right now. Talk about a major technical difficulty.
Wow. I feel better now. Thanks.
But yes. Onto the real show!
It's mad method time! You're all on the edge of your seats right now aren't you? Of course you are. I should stop asking questions to only answer them myself.
Ok.
So here it is:
Aim: To investigate/observe (and any other word synonymous to the two)how various shampoos affect the tensile strength of human hair. (more specifically, my hair)
Hypothesis: that different shampoos will result in the different tensile strength of my hair, because the ingredients in each shampoo vary.
Risk Assessment(does it even go here?)
Identify: shampoo
Assess: could get into eye
Control: Follow instructions on the bottle of shampoo and rinse out eyes immediately with clean water
Dispose: down the sink
Equipment:
1 spring scale gauge (will probably have to find an alternative)
10 mL of Head and Shoulders
10 mL of Tresemme
10 mL of this Cedel family anti-dandruff medicated foam
1 250 mL measuring container
1 thermometer
Hair (don't know how many strands at the moment)
Sheets of paper towel
Method:
1. Gather an equal number of strands of hair for each of the three trials
2. Measure out 10 mL of each shampoo
3. Mix one of the types of shampoo with 250mL of water at 25 degrees celcius to ensure fairness amongst the three shampoos, as well as reliable sources
4. Take five (number subject to change) strands of hair and place it in the mixture.
5. Stir for thirty seconds
6. Rinse the five strands of hair in 250mL of clean water for a minute by stirring
7. Dry the strands of hair
8. Using a pressure gauge measure the pressure until the breakage point
9. Record the pressure taken
10. Repeat steps 3-9 with different shampoos recording all results
11. Repeat whole experiment
Well, I'm just glad the internet didn't die on me just then. Have fun reading this rather lengthy blog, Ms.Zhang. Also, could you offer me some advice on how to measure the strength without using a spring scale gauge that isn't dodgy and will achieve good results, while still being easy to do? Thanks, muchly appreciated.
Well then, I'm off to do more science. Time to study Newton's laws ahead of tomorrow's test.
Science, how I love you so.
