For my science project, I am doing which type of aluminum foil will be corroded by tomato paste firstI recorded using YES or NOMy teacher said I did not need a standard deviationWhy not?
The only variable is in the physical properties of the aluminum foil itselfThe tomato paste is a constantDeviation comes into play if you have a 2nd variable that can affect the outcome which then brings ODDS into playSince you only have one variable, the foil, the only question then becomes how much time it will take for something that is certain to happen, not whether it will or will not happenSee the difference? Your YES/NO answer does not answer the question you are askingYou already know the outcome, the aluminum corrodes each and every time because of the acid in the tomato pasteWhat you do NOT know is the rate at which this happensWhat you should be recording is how long it takes to achieve a specific amount of corrosion, the RATE at which the chemical reaction proceeds, not whether it even happens at allBare aluminum in contact with an acid WILL corrode the aluminumNo if's, and's or but'sThings like soda cans which do NOT apparently corrode from the carbonic acid in soda, are protected by a clear coating which separates the bare metal from the acidic environmentPaint does the exact same thing for iron and steelOr an additive like chromium which alloyed with regular steel, makes it stainless steelThe chromium makes a clear tight oxide layer on the steel which acts exactly like paint, separating the base metal from the corrosive environment.
Try buying chocolate chips and follow recipe on back to make cookies from scratchOr try strawberry shortcakeOr my favorite, a fruit crisp with a peach, blackberry, brown sugar,chopped walnut, cinnimon filling with a flour, rolled oats, brown sugar ,butter, and cinnimon topping bake( Put vinalla ice cream on top if you want to look all chef like) Trust me, even the latter is easy; im not 12 yet and I can do it in my sleep.
Try making spaghetti, it remarkable convenient, rather filling, and tastes niceThis used to be the primary truly recipe I found out to prepare dinner, and I found out it for the identical intent you desire to gain knowledge of, on the grounds that I desired to aid my mother outWhat you want: ~approximately part an onion (chopped finely) ~oil ~flooring pork (or turkey) ~a jar of tomato sauce ~angel hair pasta (or any style of pasta rather) ~mushrooms, sliced (not obligatory) ~salt, pepper, sugar First, take a pot and set it to medium-prime warmth, pour a few oil in (sufficient to only quilt the backside) and upload the chopped onion in tooStir round till the onions are translucent then upload the beefBreak up the beef and as soon as it's cooked upload a bit little bit of salt and pepperSet the temperature to mediumAdd the jar of tomato sauce to the potOnce you set the sauce in, take the jar, upload approximately an inch of water, placed the cap at the jar, shake the jar a bit, and pour the water into the potStir the sauce within the pot and upload the mushroomsAdd a few sugar (believe me, you rather desire to place a few in in any other case the sauce maybe too tart), salt, and pepper to styleStir yet again, set the temperature to low, and placed a lid at the potNext, fill a separate pot with water and carry it to a rolling boilOnce the pot is boiling, upload a couple of shakes of salt and upload the pastaCook the pasta till al dente and drainLastly, simply serve up the pasta and sauce in combination, probably with a mild saladAnd you performed! If you dont desire to make spaghetti, you might continually seek convenient fast recipes on-line and spot what you discover thereHope this is helping :)
Start with the boxed mixes of muffins, cupcakes, and cakesDuncan hines is a good brandOr you can find a recipe and use that but, muffins or cupcakes would be an easy starting pointEven more so brownies especially from a box are so easy because they don't require a mixer, you mix by handThose are things I started out with at 14 and now I make wedding cakes.
Why not start with sausage rolls, quiches, mince pies, cup cakes you will find the receipe on the net at BBC good food live
