Dissolving!

Yesterday during Science year 5 investigated what materials were soluble and which were insoluble. 

We looked at what we knew about dissolving and discussed how when solids dissolve they don't just disappear! Instead the mix together with a liquid to create a solution. 

We also learnt that if a solid is soluble it means it will dissolve, where as insoluble means it won't dissolve.

Here are some people pictures of us using our numeracy skills for measuring out water to see if solids would dissolve in it. 






We found out solids such as sand, pasta and rice don't dissolve in water. Therefore these are insoluble. Other materials we tested such as salt and bicarbonate soda did dissolve and therefore are soluble. 

What other solids do you think are soluble or insoluble?
