i just read the criteria sheet. im supposed to put my results on here..
so ill do it now. basically i put all the pizzas in the oven at the same time. they were all 20cm in diameter and 1cm deep. i proceeded to check the size of each pizza every ten minutes before taking them out of the oven and recording the cooking time.

the results were as follows:



yep... do i put graphs up here too? ugh. ill do it later.

i completed my experiment today. it took a really long time and i ran out of flour. it was very difficult to do so many pizzas at the same time and i found it very frustrating. my parents weren't happy with the amount of mess i made.

on the bright side, i have found some results. on the down side, i dont really know what i can infer from these results. hopefully ill be able to figure something out. srp sucks. that is all :)

ingredients

i bought my ingredients today... im going to do my experiment on the weekend.

Risk Assessment

there arent really many risks in my experiment so im not really sure whether or not i need to do a proper risk assessment but ive done one anyway:

Risk: Oven- if left too long could overheat and cause fire
Control: Do not leave oven unattended, check that oven is safely turned off after use.
Risk: oven is hot and could burn
Control: be careful when placing pizzas in oven and removing them. do not touch any hot surfaces and use oven mits to remove trays.

and i think thats all...

Method

Hypothesis:
The rising height and cooking time of a pizza are variables that are impacted by the amount of yeast present in the base and will not be impacted when other ingredient quantities are changed.

Aim:
To prove that ingredient quantities of a pizza base, apart from the yeast, can be changed without impacting the rising height and cooking time of the pizza.

Method:
(a) Equipment:
5 medium glass bowls (labelled with: basic, yeast free, extra water, extra oil and self-raising flour)
measuring cups
measuring spoons
5 wooden spoons
Ruler
Oven (preheated to 180 degrees celcius)
Ingredients (as posted in previous blog)
Metal trays to hold pizza in oven

(b) Method:
1. collect all equipment and ingredients
2. preheat oven to 180°C
3. measure out ingredients for the basic recipe seperately as per quantities in the previous post
4. using wooden spoon, combine ingredients in the glass bowl until ingredients have become a dough- like mixture.
5. remove dough from bowl and knead until the dough is almost smooth
6. roll dough out flat and cut into a circle with a diameter of 20cm and height of 1 cm.
7. place left over dough back in glass bowl.
8. repeat steps 3-7 for the yeast free base, extra water base, extra oil base and self-raising flour base.
9. spread 2 T of tomato paste on each base.
10. sprinkle 1/2 cup of grated cheese on each base.
11. place mini pizzas in oven and cook, measuring and recording the height every 10 minutes.
12. remove pizzas from oven as they finish cooking, recording the cooking time as they are removed.
13. record all results in a table.
14. repeat the experiment with left over dough.

and thats it :)

Climate Graph

okay, so heres the climate graph. what i did was put all the information into an excel table and made two seperate graphs. i then proceeded to copy these two graphs into paint and fiddle around a bit until they become one. i hope this is similar to what its supposed to look like... :)

holidays

hi there. its been like two weeks since my last post, and i have hardly thought about SRP at all. but i thought about it today, and realised that i need to be posting "regularly". im not posting regularly, but im posting every now and then so hopefully that counts for something... :S

anyway, like i said its holidays and ive been busy doing fun things and not thinking about school which has resulted in no SRP progress. as i said in my last post though, im not really sure what else im supposed to be progressing on... ive done my pre-experiment research and i will work on my method in the near future. once ive finished procrastinating that is.. am i supposed to put ALL of my research on here? because i havent... not that theres really that much.

this was probably a waste of your time to read, since i havent made any progress at all. sorry about that... whilst writing this though i have been thinking about what im going to do for my method and that has to count for something right?

ive decided to go with your idea of making quite small pizzas so that all of them can be cooked at the same time. they will in fact be round pizzas, and will all be the same diameter. i will make sure of this by skillfully measuring with a ruler :) at the moment i am unsure of what that diameter will be, but i will figure it out. it might change when i do my experiment anyway depending on whether i can fit each base into the oven. theres three oven trays though, so im fairly sure they will all fit..

mhmm, well thats it. im going to laser tag :D
