Exploring Mixtures vs Solutions

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?.

  1. When the kids are a bit overtired and getting them in the bath is a bit of a hassle we play the game “sink or float”. I get a number of different items and the kids have to guess before I put it in the bath if it will sink or float. They really enjoy it every time.

  2. At school we were taught the difference between mixtures and compounds too – we were given the following analogy and I can still clearly remember it now, about 8 years later!! :

    Imagine a bag of sweeties (candy) – You can shake them around, throw the bag, whatever, but when you open the bag you can still pick out individual seperate sweets… this is because it is a mixture. BUT, If you emptied the sweets into a frying pan and heated them up, they would all melt together and fuse – you can no longer pick out individual, seperate sweets – this is the same as a compound… (obviously you could actually do this for real too!!) =]

  3. so inspired by your experiment to start doing something like this with my kids! they’re a little tired of the crafting, so I guess I need to move into the science department! (and thankfully there were 3 links on Craft Schooling Sunday with science oriented projects!) all the best and thanks for sharing on Craft Schooling Sunday!

  4. This reminds me of all the experiments I did with my boys years ago when I homeschooled. WE will not mention how very long ago that was!
