mixtures

Today in science we learnt about mixtures!

My first mixture was sand and salt we put a little bit of each on the watchglass and took a photo of it.

 

In the photo you can see salt and sand.

You can see the different grains (salt and sand).

You can separate it by sieving it because the salt is bigger than the sand.

 

We also did a mixture of flour in a test tube of water (the little particles floated around in the water and then sunk to the bottom).

Our final mixture was made of oil, detergents
