This activity allows children to demonstrate their understanding of what gravity is, how it is measured, and to practically investigate and compare the weight of different objects. The objective is to understand that gravity gives us weight, with the following steps to success: - I know gravity is a force - I know that gravity affects the weight of objects - I know that weight is measured in Newtons - I can measure and record the weight of different objects Challenge: I can explain the difference between weight and mass The worksheet involves children being able to explain the difference between weight and mass, to draw a newton meter, and to use one to measure the weight of different classroom objects, recording their results in table form. This worksheet can easily be adapted for different classes and abilities.
