Students identify the most appropriate apparatus to sort different kinds of materials.
As part of their Science unit on solids, the Year 5s are becoming accomplished in sorting and separating a variety of objects.
After looking at a range of scientific equipment in the lab – tweezers, sieves, magnets, spoons – Mrs Hall engaged the girls in a practical task during which they had to separate a succession of solids.
They made predictions on which tool would work best with which material. Would a sieve be effective for sorting rice? If not, why? Would tweezers be the easiest means to separate pasta from flour, and what could the students use to sort gold particles from fine-grained sand and coins from marbles?
Once they had trialled the equipment, the girls recorded their results, ready for group discussion and analysis.
