Question

Oh my gosh! can someone help me with my lab experiment? Its an easy question i just need help. :(

Answer 1

Sure Madam I can Help you.

Answer 2

Devon Sharrock, Are you there ?

Answer 3

for my experiment, i am finding out if dding sugar to water changes the thickness and stickiness. my material are measurg cup water, sugar, spoon, microwave. i conducted 3 experiments i mixed sugar in col, warm, then hot water to see the difference. i was just wondering what are ym dependant, control, and independant variable in my procedure?

Answer 5

@abb0t

Answer 6

* control variables are the things that are not changing.
* Independent variables: the things that you change.
* Dependent variables: the things that are changed due to the independent variable

Answer 7

i know what they all mean but im having trfin out which ones in my experiment. i asked my dad and he doesnt know either

Answer 8

Answer 9

Take a guess what do you think it is. If you are adding stuff, that means that you are changing it. What is making it change?

Answer 10

the temperature is making the change?

Answer 11

Yes. And you are controlling the temperature, yes? So therefore, that would make temperature ____________________ variable.

Answer 12

the independant!

Answer 13

Yes. Anything that yu have control over is an independent variable!

Answer 14

sp it can be more than one?

Answer 15

Yes.

Answer 16

how about the amount of water and sugar then?

Answer 17

You poured the amount of water and sugar, therefore, that makes it _______________ variable?

Answer 18

You can always add more or less water/ sugar. Remember.

Answer 19

independant because im controling how much?

Answer 20

Yes.

Answer 21

but i also keep the same amount in each trial so does that also make it a control variable?

Answer 22

Well, if you kept the amount the same, then that is your _o________ .

Answer 23

control variable

Answer 24

Yes.

Answer 25

so can materials be controlled variables because those dont change either?

Answer 26

@abb0t

Answer 27

If you don't change it, then it is controlled. In this case, the water is controlled.

Answer 28

and the sugar?

Answer 29

No! Because you're adding it to the water! You're changing the amount of sugar in the experiment. If you left the same amount of sugar and kept adding water, then water would be independent and sugar would be controlled!

The sugar itself is part of the experiment. Do not think of the materials. you cant change the shape of the cup, but it is not part of the experiment, doesn't mean it's a control. You're only referring to the experiment itself.
Or the spoon you used to stirr. Just because the spoon doesnt change, does not make it a control.

Answer 30

yeah but im not changing the sugar amount in all 3 trials im adding the same amount of sugar and water. the only thing im changing is the water temperature

Answer 31

Then the temperature would be the independent variable. Viscosity would be the dependent because that's what you're testing for

Answer 32

what would the water and sugar be then?

Answer 33

I would say temperature is not the independent variable but the temperature of the water. I guess, the amount of sugar would be control because it's fixed.

Though, when i think of control i think of a trial in which the outcome expected is known, to test for deviations with the apparatus, or other things you can't account for.

Answer 34

I think @aaronq is right !
