This week’s science is all about materials that will dissolve. Some solids will dissolve in water to form a solution. These materials are known as soluble. Your challenge is to investigate which solids around your house will dissolve in water. Try mixing a small amount of the solid with water and observing what happens. You could try: salt, sugar, sand, soil, flour, chalk…
(Remember to ASK AN ADULT before you raid the kitchen cupboards!)
It would be brilliant if you could do this practically, but if not, you could always research the answers instead. The links below give you plenty of information to get you started.

We would love to hear what you have found out. You could take photographs, write up your investigation or create a table of your results – it’s up to you!
Extra Challenge: Can you investigate whether those solids will dissolve in other liquids, such as cooking oil?
