Question

PLEASE HELP ME FIND THE CONTROL GROUP, INDEPENDENT VARIABLE, AND DEPENDENT VARIABLE FOR THIS EXPERIMENT
-EXPERIMENT IS BELOW

Answer 1

there has to be an expirment????????????????????????? where is it :)

Answer 2

im trying

Answer 3

ok

Answer 4

okay

Answer 5

if u cant see it clearly heres the link:
http://www.wikihow.com/Make-Hot-Ice
and scroll down to the homemade how to make sodium acetate

Answer 6

The dependent variable is the variable you measure.

Answer 7

so what do you think it is?

Answer 8

so its the amount I put vinegar and baking soda

Answer 9

yep

Answer 10

6 tablespoons of baking soda 2 liters of white vinegar to the baking soda

Answer 11

im sorry i meann what your measuring to make the solution

Answer 12

ndependent variable is the variable you manipulate

Answer 13

so whats the dependent variable

Answer 14

how do you measure the results of the experiment? what you are measuring for that result is the dependant variable

Answer 15

thats what idk

Answer 16

it would be the baking soda

Answer 17

altogh it also could be the vinger

Answer 18

as the dependent variable

Answer 19

So the dependent variable(s) are baking soda and vinegar

Answer 20

too many typos :)

your experiments is a success, or a failure depending on what the outcome is .... what are you measuring to determine the success or failure of the experiment?

Answer 21

take a look at this

Answer 22

in an experiment, the independent variable is that which you have control over. It is the variable that you change to effect an outcome. So inthis case its the amount of what?

Answer 23

yes

Answer 24

yes? that wasnt a yes or no question :)

Answer 25

vinegar and baking soda? (thats what Im taking control over right!)

Answer 26

yes

Answer 27

so its not the dependent variable its now the independent

Answer 28

variable

Answer 29

yes and what do u think is the dependent varible

Answer 30

The dependent variable is the one which you will observe for change.

Answer 31

so i just losed it
a minut ago i had the naswer but i just losed it ! uggggg!

Answer 32

sorry to many typos

Answer 33

ok the dependent would be the viger and baking soda

Answer 34

both the independent and dependent

Answer 35

right?

Answer 36

what is the control group

Answer 37

? please

Answer 38

im not sure about the controlled and independent

Answer 39

in an experiment, the independent variable is that which you have control over. It is the variable that you change to effect an outcome. So in this case its the amount of baking soda and vinegar is independent variable

Answer 40

experimental group - group that is subject to your changing variable
control group - group that is treated exactly like your experimental group except for the variable you are testing.

Answer 41

im not sure

Answer 42

Where are you stuck?

Answer 43

finding the independent dependent control experimental that stuff :(

Answer 44

Indep is something you CAN control.
Dep is something you CAN'T control.

Answer 45

WHAT ABOUT THE CONTROL GROUP AND EXPERMINTAL GROUP?

Answer 46

SO WHAT IM TAKING CONTROL IS THE AMOUNT OF BAKING SODA AND VINEGAR SO THATS MY INDEPENDET VARIABLE
THEN WHATS MY dependent variable

Answer 47

AND YOU'RE USING A LOT OF CAPS.

Answer 48

SO WHAT IM TAKING CONTROL IS THE AMOUNT OF BAKING SODA AND VINEGAR SO THATS MY INDEPENDET VARIABLE: YES.

Answer 49

sorry forgot that i had it on:) im not trying to emphasize my question :)

Answer 50

then whats my dependent control and expermintal

Answer 51

What are they both producing?

Answer 52

sorry if it looks like im pressuring u :)

Answer 53

okay the dependet is the variable u cant control : so its the solution( baking soda and vinegar solution?)

Answer 54

?

Answer 55

OMG! YOU ARE PRESSURING ME LIKE A LOT!!!!!!!!
*sarcasm*

okay the dependet is the variable u cant control : so its the solution( baking soda and vinegar solution?)
No.
What's the outcome of the solution? THey react and form something right? That will be dep.

Answer 56

so its sodium acetate ( hot ice)

Answer 57

^ there is your answer.

Answer 58

yeah! u know ur the only one that helped me go through this thanks! others were just like guessing

Answer 59

You owe me a cookie then.

Answer 60

okay so now what the control group

Answer 61

yes ull get ur cookie one day!:)

Answer 62

hello ! :) still neeed help here! :)

Answer 63

Not sure about control group.

Answer 64

what about expermintal group

Answer 65

does my experiment even have a control group?

Answer 66

Not sure about that either.
http://chemistry.about.com/od/chemistryterminology/a/What-Is-An-Experimental-Group.htm

Answer 67

The difference between a control group and an experimental group is one group is exposed to the conditions of the experiment and the other is not.

An experimental group is the group in a scientific experiment where the experimental procedure is performed. This group is exposed to the independent variable being tested and the changes observed and recorded.

A control group is a group separated from the rest of the experiment where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternate explanations of the experimental results.

Answer 68

but does my project have those?

Answer 69

making "hot ice" is not an experiment

Can you post exactly what the assignment is ?

Answer 70

okay please hold on :)

Answer 71

okay its that http://www.wikihow.com/Make-Hot-Ice thats my assigment

Answer 72

there are two ways of doing it and i chose the second

Answer 73

i need a control and experimental group

Answer 74

and thats it:)

Answer 75

OK, but this is not really an experiment. An experiment tests some idea.

For example. at step 7 they say
Add a bit of crystallized sodium acetate to your aqueous solution. Use the powder scrapings you removed from the pot while you were boiling down the solution. Start with a small pinch or two; if they have no effect, add a larger amount.

An experimenter might want to test the idea of "how much" of a bit should be added.

If you did this (and it looks like a lot of work), you would say the independent variable is "how much is added" (you would weight it)
the dependent variable could be "it had an effect with 5 minutes"

the control would be a solution with nothing added-- how long (if ever) before you see an effect ?

the experiment (lots of them if you want to) would be
to add a measured amount to a new solution and see if and when there is an effect.
if you did that for 5 different solutions, with each one having slightly more sodium acetate added, you could get numbers on how quickly you see an effect, based on how much you added.

That would be an experiment.

Answer 76

okay im chagnig my experiment http://video.about.com/chemistry/How-to-Make-Hot-Ice.htm#vdTrn this is my experiment

Answer 77

You seem to be missing the idea.... making this stuff is not an experiment.

It is a "project". If you make it, there are no controls, no dependent and no independent variables. This may be ok, if the assignment is make hot ice.
But if you have to do an experiment, you need to test some idea. A real experiment is harder to do than just make hot ice.

Answer 78

okay i agree with you but i have to do this

Answer 79

Here would be an experiment:
make hot ice using vinegar
try making hot ice using lemon juice. Does it still work?
now you are testing if you can replace one acid with another.

Answer 80

okay isee then whats my dependent control, experimental group

Answer 81

You should think about that: what would you change ? (that is the independent variable)
the dependent variable is: you create hot ice (or not)
the control experiment is with vinegar
the experimental group is with the lemon juice.

Answer 82

independent variable: the solutions

Answer 83

right?

Answer 84

yes.

Answer 85

idk whats the dependent

Answer 86

if you switch from vinegar to lemon juice what might happen ?

Answer 87

http://www.cool-science-projects.com/independent-and-dependent-variables.html

Answer 88

you might not get hot ice. So hot ice is the dependent variable: how much if any is formed if you switch from vinegar to lemon juice.

Answer 89

kk then i got that right thanks for ur help!
