The children were challenged to separate the mixtures put in front of them.
Plastic beads and paper clips
Sugar and marbles
Pasta and sugar
Water, pasta and sand
Water, sugar, pasta and sand
They were asked to think about the equipment they would need to ask for but couldn't use spoons, fingers, pieces of paper to scoop out the objects or a pencil!
Eventually, they managed to work out that they needed a sieve (magnets for the paper clips) although this still caused problems for the sand, water and pasta mixture.
