more info on experiment

today i just realised that i had to make more than one muffin with the same amount of bi carb soda in it grrr

which will make it VERY complicated if i bake all the muffins in one day so i will probably be baking 4/5 diff batches on diff days. this experiment will make my family sick of muffins for a while.... and also just for the marking schemy thingo maboby the:

independent variable : amount of bi carb soda
dependent variable: height of muffin

so i think i've got all the variables that should be the same eg. ingredients, baking time, mixing time and thats about it. i can probably do this experiment over 2/3 weekends or maybe 4 or 5 weekends or maybe 6 or 7 weekends. ionno anywayysss good bye

info on project

thinking about what equipment is needed for experiment, mine is pretty easy simple

need:

• oven
• cupcake tray
• labelled patties - tell how much amount of bi carb soda is in each
• bowls/spoons
• electric beater
• ingredients (flour, sugar, salt, bi carb soda, water, milk butter)

info on bi carb soda

http://aww.ninemsn.com.au/food/cookingtips/790073/baking-soda-bicarb-soda-baking-powder-whats-the-difference

"When included in a batter, the leavening agent causes air bubbles (produced by stirring, whipping or beating) to expand when cooked – causing it to ‘rise’."

this means the time and the strength used to mix the batters will have to be the same, probably be using electric beater for most accurate results.

things that could make the results in accurate: the diff levels of stirring/whipping for each batter.

and also, washing the electric beater for diff batters is important so that the levels of bicarb soda are hte same, but the batter thats left stuck on the beater will minimize the amount of bi carb soda in the batter. URGH not such an easy experiment. dammnitt

science SRP ideas

okay here are a list of ideas that i wanna do for my srp

• see how long it takes to dissolve different types of lollies ( too many variables)
• how diff levels of bicarb soda affects the height of muffins

and uh i can't really think of anything else at the moment. i am looking through science fair projects but they are all at a primary school level. i will probably do the muffin idea - will start researching soon.

about the muffin idea:

the sugar, flour, egg, milk, butter will be the same for every muffin obviously and the only thing that will be changing is the amount of bi carbonate soda/baking powder. found a simple muffin recipe which has the amount of baking powder shown separately from the flour so that i can change the amount of the baking powder without changing anything else -

but i will probably be replacing the lard with butter or something else which sounds less vomitrous.

update: found a better recipe which does not include lard - blergh - http://www.kitchencookingrecipes.com/recipes/basic-muffin.html

soo most probably using the muffin idea woohoo! problem 1 solved.

um about the size of the muffin, it will probably be about 1/2 table spoons per muffin of muffin mix, not including the amount of baking powder, which means there will be a lot of seperate bowls and washing up to do.
