This term in Science we are learning how make predictions about and experiment with dissolving things in water.
We are learning how to relate our findings to the world around us.
Key Skills
To be able to investigate the difference between soluble and insoluble substances.
To be able to investigate what makes things dissolve more quickly.
Key Knowledge
Dissolving is when a solid gets mixed in a liquid and creates a solution.
A solution is a brand new thing made from mixing a liquid and another material which dissolves in the liquid.
If something is soluble, it dissolves entirely in the liquid.
If something is insoluble, it does not dissolve in liquid. For example, if you put a plastic dice in water, it would not change. The dice is insoluble in water.
We have conducted lots of different experiments 🧪 first we dissolved sugar at three different temperatures to create a solution. Then we experimented to see if sand, salt and oil dissolved. We also watched jelly dissolving. Lastly we discussed saturation point and carried out an experiment with sugar and water.
