Investigate why boats float
This is one of a series of resources from the Institution of Engineering and Technology, produced in association with Fairfield Control Systems, exploring the theme of waterways.
In this activity pupils will learn what is meant by density and will conduct an experiment to find out if modelling clay moulded into different shapes sinks or floats. They will discuss why this happens and how the principle demonstrated allows boats to stay afloat.
Learning outcomes:-
- understand that if two things are the same size, the one that is denser is heavier
- know how boats use the Archimedes principle to stay afloat
