I put this lesson package together for a super hands-on, kinesthetic science day for my Y2s- though it would be ideal for lower KS2 as it takes the concepts of floating and sinking further to include density. This lesson includes: A 17-page Smart Notebook A comprehension about Archimedes Float or sink investigation sheet Differentiated float or sink write up sheet Float or sink challenge write up sheet Particle colouring for the hats - which the children loved wearing all day During this lesson, the children investigated which objects float and sink and made rafts to help heavy objects float. Their scientific minds were challenged as they tried to work out why things they thought would sink, floated, and vice versa. This 17-page Smart Notebook takes the children step by step through the day (or possibly 3 to 4 separate science lessons) so that by the end of it, they can explain that the density of particles in an object, determines whether the object will float or not. We played a game in the hall towards the end of the day where I challenged two teams to get into the particle formation of a metal fork (ie very close together and in the shape of a fork) or the particle formation of a cork (particles further apart and in the shape of a cork). They absolutely loved this!! The children loved the practical elements of this lesson and learnt so much and presented their findings to the rest of the school at the end of our whole school science day. All the resources are editable.
