Mass or Weight?

In Room 16 we have been looking at mass and weight. We learnt that it is best to use the word mass as weight changes. For example if you weigh 50kgs on Earth you would weigh 1350kgs on the sun due to gravity but your shape or mass would still be the same. 



Checking boxes and containers to see how many grams of food they contain
We had three different items to order from biggest to smallest mass or biggest to smallest number

 Each group had to bring their items to the mat and order them 

The ice cream cones had the lowest mass, 70g (even though it was a big box) and the sugar and yogurts had the biggest mass, 1kg. 

1kg = 1000g because kilo = thousand
