Our science focus this week has been investigating substances that will dissolve in water.  We had 4 substances to test – sugar, flour, salt and sand.

First, we made our predictions, then it was time to test!  We set up a fair test using the same amount of water for each jar, the same amount of each substance and we stirred each jar the same number of times.

We made some interesting discoveries and are already thinking about what we want to change about the investigation next week.

Some pupils want to see if the water temperature will affect how quickly a substance will dissolve.  Others want to try adding different amounts of water and some spoke about stirring the water for longer.

We are excited to test out our ideas next week!
