For this hypothesis...?

Question

"Do different brands of orange juice contain different amounts of vitamin C?"

What are the independant, dependant, controlled variables and what are they measured in?

thanks =]

Answer 1

There is going to be so much vitamin C in the brands that it isn't going to have any practical significance. If all of the juices give you 100% of your daily allowance, it doesn't really matter which one has more, especially if it's only by a little bit. This also isn't really a great example of an "experiment" in the strict sense of the word. All of those things said, it is kind of interesting.

Was also wondering how you would measure the vitamin C???

Answer 2

Like I said in your last question, this isn't an experiment.  Reading the back of a box doesn't give you a control group or any variables to work with.  Find a new topic.

Answer 3

Don't worry about vitamin C. That was a 70's thing and so was TV advertising on how good asbestos was.

Answer 4

Control would have to be fresh squeezed oranges.

The problem here is there are so many different types of oranges you may not be able to accurately test this.

Answer 5

idk

Answer 6

that's not a hypothesis. a hypothesis is what u think will happen, like ur prediction. like i think tropicana orange juice has a higher level of vitamin c than minute maid orange juice does.

Answer 7

Vitamin C is citric acid.

The primary contributors of developement of this within a fruit are soil content, sunlight and moisture.  Also, the strain (species) of tree, the age of the tree, the weather during growth, and the age of the fruit during picking will alter the percentage of acid.

Some juices are "made from concentrate", while other manufacturers will add citric acid (and fructose &/or oils) to make juices taste more real.

Acid is measured in a "Litmus" scale where sulphuric acid is dangerous, and vinegar is mild.  Water is generally neutral, and on the other end of the scale, Lye and Chlorinates are dangerous, while soap is generally mild.

Independant: Species of fruit

Dependant: Sunlight and soil, agriculture methods and weather.

Controlled: Additives and manufacturing methods

Measurement: Litmus scale

Answer 8

independent variable means what you are using experiment on? what is it that you're tyring to manuipulate.

dependent means that are you trying to measure here? the dependent variable depends on the independent variable.

controlled variables are those that you don't change. they just stay the same, like a placebo so you can measure any differences with the other variables. i can't give you any more infor because you didn't give any more info.

Answer 9

Orange juice is orange juice the freesher the better and brands make no difference..actually as a health drink organge juice is not that good..cranberry juice is better for your bladder and colon

Answer 10

use laxitives

Answer 11

The control would be a fresh orange. But there are thousands of different types of oranges. Therefore I suggest finding a new experiment.

Answer 12

the independent variables are the different  juices and the dependent variable is the amount of vitamin C. The contolled variable is the volume of the juice.

Answer 13

some juice manufacturers (usually the most renowned and expensive) add extra vitamin "C" and lots of sugar and in many cases food coloring for all the obvious reasons but V"C" is readily expelled from the body and therefore any OJ will provide (as do fresh oranges) sufficient doses of vitamin "C" all the extra is passed quickly w/out simulation into the body>Orange juicers usually utilize the fruit that is less desireable to sell in its whole form (usually green premature or  bruised  overripe bug-holed otherwise abverse conditions(thus the added color and sweeteners)FIGURE THESE FACTORS INTO YOUR HYPOTHESIS

Answer 14

Tropicanna is the best. it is 100% pure and has pulp.
