1 What are mass and weight and what are the units for them?

2 Objectives Explore what mass and weight are and the difference between them. Outcomes (5) Define mass and weight (6) Calculate the weight of a range of objects. (7) Analyse why weight can be changed but why mass cannot. Key terms: Mass, weight, force, Newton, gravity, matter.

3 Tasks Using the balances, scales and newton meters calculate the mass and weight of a range of objects. 1. Design a table. 2. Gather results 3. Come up with a rule for the relationship between mass and weight. Outcomes (5) Define mass and weight (6) Calculate the weight of a range of objects. (7) Analyse why weight can be changed but why mass cannot. Key terms: Mass, weight, force, Newton, gravity, matter.
