A mixture is a substance in which two are more substances are mixed but not joined together, meaning that a chemical reaction has not taken place.
You can make many mixtures with many every day things.
1. Firstly try to make a mixture of toys!
2. Secondly, sweeties! (Pick ‘n’ Mix is a mixture all in a tub!)
Then you can actually mix some mixtures!
How about a cup of tea! The tea, water, sugar and milk all makes a nice mixture.
What about salt in water? What do you notice happens to the salt?
Water and liquid soap
Milk and milkshake powder! Yummy!
Solutions are mixtures when a solid (which we call a solute) dissolves into a liquid (that we call the solvent)
Aim: To test out these three mixtures to see which form solutions and which don’t?
- Salt and Water
- Sugar and Water
- Sand and Water
You should find that both salt and water and sugar and water dissolve and form solutions and that sand sinks to bottom!
