KS1 float or sink objects activity worksheet resource

Perfect for either EYFS or KS1 children as they learn how to handle both man-made and natural objects. This beautifully-designed activity worksheet guides children to explore how objects perform when placed in water and supports them as they understand the difference between floating and sinking. 

How to use this resource

This worksheet can be used in combination with our complete Float or sink investigation lesson for KS1 which helps children explore the properties of a variety of objects and the effects of putting these into water.

This resource supports children to work with a range of objects, put them in water and decide if they float or sink. There is a simple tick box activity for them to complete to show their results. 

You can also use this worksheet as a standalone activity to support scientific learning in the classroom. It could also be used as a homework task, where children find objects at home and carry out their experiments to report the results when they return to school.
