Science Buddies: "Ask an Expert"

Hello I was wondering I am doing the electrolyte challenge and I know I am going to sound dumb but how do I make a hypothesis when I am trying to figure out which is the best drink? Unlike the examples in your "how to make an hypothesis" section. This experiment is which drink has the most electrolytes and though the independant variable is the drink and the dependant variable is conductivity I just don't know how I would word my hypothesis without making it a prediction. I would appreciate any help and i am not asking you to do it for me but just hints as to how i will word it. I am trying to figure out which drink has the most electrolytes. I just can't pinpoint the relationship I am examining

Thank You

PS
I am doing multiple drinks other than just orange juice and gatorade

I am also doing a test with this to confirm my results in the other section.

Hi and welcome to Science Buddies!

In general, when constructing a hypothesis, you want to tailor it to the purpose of your experiment. So, a null hypothesis would simply state that your independent variable had no effect on the dependent variable. An alternative hypothesis would have more variation, as that is the hypothesis that you are constructing. In order to make your hypothesis sound as a factual statement, make sure to construct it as a statement rather than an opinion.

If you are still confused, you can also use a formulated hypothesis. The most common would be the if-then statement. This formula uses if (IV), then (DV). This formula can be altered to fit almost any hypothesis needs.

In terms of identifying the relationship that you are testing, think of you IV and DV. Since the IV is the drink, and DV the conductivity (most likely used as a proxy measurement for electrolyte concentration), I would say that the clearest relationship to examine for your project would be between each drink and their electrolyte concentration.

If you are still confused, Science Buddies has great resources for hypothesis construction, which I know you already visited. I also linked another website below that I found helpful. Let me know if you need anything else!

If electrolytes are related to conductivity, then beverages with more conductivity will have more electrolytes.

The above is what I have done but is it possible to get rid of the "if" and "then" with some other word or another way to rephrase it but still keep it an hypothesis statement. Also is it good?

The only problem is that the statement is only one sentence, how would I make it so that there is more to it.

Thank You Ashley for spending time to help for a matter that is not important enough to be answered.
Thank You !!!!

Hello

Can you someone please help.

Can someone please explain the purpose for using the multimeter to measure the distilled water?
Is the distilled water to be used as the control?

thank you!

Yes

Can someone please help me . Really sorry for sounding impatient but my due date is close.

Your hypotheis is a prediction. The purpose of the experiment IS to prove or disprove your prediction.

You can try phrasing it as something like this:

I believe Gatorade will have the most electrolytes because professional athletes endorse the brand

Or,

I believe Powerade will have the most electrolytes because it is the most expensive compared to other drinks.

Or,

I believe Body Armor will have the most electrolytes because it has more sodium listed on the nutrition label than the other drinks.

i know these sound a bit ridiculous, but the example is to show how you are predicting an outcome and then supporting that with a statement.

Does this help?

Hello Kimma
Sorry but a hypothesis is not a prediction as ashley has explained.
It is a relationship between the independent and the dependant variable with the hopeful outcome.
The examples you said are simply predictions you made based on certain elements.

All I want the experts to explain is for them to tell me if my hypothesis makes sense, a way to add more to my hypothesis and also a way to reword it so that the words "if" and "then" are not included.

Hopefully the experts will answer your plea. Was just trying to help.
Good luck
