Year 5 carried out a science experiment to separate a mixture made of raisins, sugar, and flour. They discussed the best methods to separate each material based on its properties.
First, they hand-picked the raisins. The raisins were much larger and darker than the other ingredients, so they were easy to see and remove by hand.
Next, they used a fine sieve to separate the sugar and flour. They discovered that the sugar grains were larger than the flour particles. When they shook the sieve, the sugar stayed on top while the finer flour particles passed through.

By using these methods, Year 5 were able to separate the mixture into three different materials: raisins, sugar, and flour.
