Please help me with my homework! OK, so there is this girl conducting an experiment to see whether a solution (juice) will take longer to freeze than a substance )pure water).She predicts that water will take less to freeze. So there is this article that goes on and on to list the steps that she took. I have to answer these question. PLEASE help me. I put the answers that I put into my homework below each question. Please tell me if my answer is incorrect, and if so, how could I fix it. Thanks in advance!
1. What is her hyothesis?
A solution will take longet to freeze than water.
I MOSTLY NEED HELP ON THIS QUESTION!
2. What are the variables in the experiment?
Independent Variable- Juice/water.
Dependent variable- Ammount of time that it takes to freeze.
3. What variable is controlled?
Ammount of juice/water put in cups.
you have it, I would also list as a control the same freezer at the same time.
Without the material (experiment) you are following I can't help; however, here is a site that explains dependent and independent variables.
independent versus dependent variable
The link didn't come out. Here's another try.

1. What is her hypothesis?
Her hypothesis is that the solution (juice) will take longer to freeze than pure water.
Your answer for question 1 is correct.
2. What are the variables in the experiment?
a) Independent Variable: The type of substance used (juice/water). This is the variable that is deliberately changed or manipulated by the experimenter.
b) Dependent Variable: The amount of time it takes for the substance to freeze. This is the variable that is being measured and is expected to be influenced by the independent variable.
Your answer for question 2 is correct.
3. What variable is controlled?
The variable that is controlled in the experiment is the amount of juice/water put in the cups. This means that the researcher ensures that the same amount of juice/water is added to each cup to maintain consistency and to eliminate this factor as a potential influence on freezing time.
Your answer for question 3 is correct.
Overall, your answers seem to be correct. However, it's always a good idea to double-check the original article or experiment details to ensure accuracy. Additionally, make sure to review your answers for spelling and grammar errors before submitting your homework. Good luck!
