This week in science Year 5 were looking at what happens when we put a solid into a liquid. On Tuesday they planned, carried out and concluded an investigation into variables which affect the rate at which salt or sugar dissolve. We worked together as a class to explore this question. Some children investigated different types of sugar, others discovered whether salt or sugar dissolved more quickly. Another group worked outside with Mrs Khan and Mr Inman to put different variables to the test!
But I still have some questions for you, Year 5:
What did you find out?
Why do you think this happened?
What further tests could you carry out to confirm your explanation?
Do some research into what happens when solids dissolve in a liquid. Why would some solids dissolve more quickly than others?
(Clue: Look at the particle arrangement!)
Let us know what you find!
