Science: Mixture vs. Solution

In Science we have been working with water & reading about all the things it can do. Today, we read about solutions & mixtures and set out to make our own!

We gathered our materials. Reese chose what we would mix into the water...
oil, flour, sugar, blue food coloring drops, sand, & red powdered paint.
We made our predictions on which would become a solution & which would remain a mixture...
Reese was in charge of the mixing & observing...

And tasting...

he wanted to see what the blue food colored water tasted like...

gross....

and I had to stop him after a few sips because I just couldn't stomach feeding my child a cup full of food coloring!

We used a filter to see if we could separate the particles...

Reese watched to see if our predictions were correct...
Mixing our red powdered paint...
Mixing oil & water...

Once we were finished, we recorded our observations...

I'm still not sure about the flour though. When we stirred it, it looked like it had completely dissolved and was gone. But after it sat and I was cleaning up our things, I noticed a big lump of flour at the bottom of the glass, so I guess it remained a mixture?

Awesome experiment! You guys do the coolest things. I LOVE that he had to taste the blue water :)
