Mass vs. Weight
Weight
Weight - the amount of gravity pulling on an object
Weight is measured in Newtons (N)
Weight is measured on a spring scale. It shows how much gravity is pulling on an object (like the fish in the left picture)

Mass
Mass - the amount of matter in an object
Mass is measured in grams (g) or more often kilograms (kg)
Mass is measured on a balance. We have triple beam balances at school. This way the 2 objects are balancing against each other instead of gravity.
