What is the most widely consumed natural resource on the planet after water? Most people are surprised to find out that it is sand. 15bn tons are used annually – worth £100bn!

- planning different types of scientific enquires to answer questions, including recognising and controlling variables where necessary
- using test results to make predictions to set up further comparative and fair tests
- taking measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings where appropriate
Children will learn:
- to appreciate that sand is a naturally occurring material and an increasingly rare resource
- how sand is formed and that it has many uses
- to explain that sand is a component in many important building materials, including concrete and glass
