In Science we started a new topic ‘Mixing and Separating’. Today we discussed that a mixture is a number of different materials combined together that don’t react chemically, meaning no new substance is formed.
The children were challenged to separate rice, sand and gems by making a sieve out of a piece of card. Some of them were more successful than others and in the end, they realised that the holes in their sieves had to be small to let the sand particles through first. They had to then make larger holes to sieve through the rice and then they would be left with the gems.
Have a look below to see how they did!
