IS IT A MIXTURE :)
by Brooke - Thursday, 19 February 2009, 11:10 AM
A tossed salad is a mixture because you mix all the vegtables together.
A chocolate cake is not a mixture it is chemical change , you have to cook it.
A pitcher of kool aid is not a mixture because the powder disolves and becomes as water.
salt water is mixure because when you boil the water you get back salt!!
An omlet is not a mixture because the egg was once liguid and then when you cook it it is now a solid
Go Brooke! Great Job!
I agree, if you cook it, it’s probably a chemical change. Excellent job!

That’s a really good answer Brooke. I think you got a 100%. Well, I’m not grading it BUT, if I was you would get a 100% definitly.
P.S. I need a review if you would please respond that would be great.

Let's look at the pitcher of Kool-Aid again. Yes, the powder dissolves, but doesn't that happen in a mixture/solution? Could the same process work with Kool-Aid as it did with salt water (evaporate the water)? Is there any indication of a chemical change present in mixing Kool-Aid and water?
That’s a really good point. Thanks sorry.
Don’t be sorry! This is a great time to talk about misconceptions in science. Many students think that since Kool-aid changes color of the water, it is automatically a chemical change. Think about it on a molecular level and the particles. Do you still just have Kool-aid and water? Or is a new substance formed?
Im not sure when you boil it if you get the powder. Can I try it?
I think it would be worth trying. Just put a small amount of Kool-Aid and water in a saucer and let it set out for a couple of days. Let us know what you discover.
Ok I will get back to you.
Mrs. King? What would happen if you boil powder? I don’t need to know now because Brooke hasn’t done it yet and I don’t want to runie the surprise.
I know I spelled ruine wrong and I don’t know how to spell it, but I tried.
Well…lets think about it…can you boil a powder? No, most likely the heat will eventually burn the powder on the bottom of the pan. However, if you put water and powder together you could boil off some of the water, until all that is left is the powder. Of course, you would want to do all of this with adult supervision.
So you said the powder would stay at the bottom of the pan if you boiled water and powder, so would the powder by dry like the beginning or would it be clumped together? Like it got wet?
Mrs. King, if you boiled plain powder would the powder become hard like a cookie?
That’s a good question… The act of boiling requires a liquid. My guess would be that the powder would burn or melt. It would depend on the chemical properties of the powder you are working with. Why don’t we explore what happens when we heat substances at our next face-to-face meeting?
