WALT: measure mass in grams (g).



In this lesson we will be learning how to measure the mass of different objects.

When we want to find the mass of small, everyday objects, we measure in grams. Grams is shortened to ‘g’.


Using grams

Here are some objects that you might be able to find around your kitchen. They are small objects and can be measured in grams.


Let's look at how much they weigh:

  • An egg weighs 60 grams or 60 g.

  • An orange weighs 250 grams or 250 g.

  • A bottle of milk weighs 800 grams or 800 g.


How do we measure the mass of objects?

A common way of measuring the mass of objects is to use balance scales. A balance scale works by placing the object you want to weigh on one side and adding gram masses to the other side until the scales are level. There are other types of scales you can use to measure mass. You can also use a set of scales showing the mass on a dial with a pointer or digital scales showing the mass as a number.
