WALT measure Mass

We discovered lots about Mass - weight.  We used lots of equipment to see what was the lightest and heaviest.  We used our hands, balances, and scales.
We were able to find out which toy was the lightest and heaviest by balancing them with cubes and counting the number of cubes.

We were able to order containers that looked the same but had 1 cup of different things in them by comparing them with our hands. We discovered that 1 cup of rice bubbles was the lightest and 1 cup of rice was the heaviest.

Some of us added water to a drink bottle until it weighed exactly 500 grams, and added play dough to the bowl until it weighed exactly 1 kilogram!

We balanced the scales with 2 different objects.

We measured the weight of the basket by adding 10 gram weights until the scales were balanced.  We discovered that the basket weighs 180 grams.

We also tried to balance ourselves on the balance board.  It was very hard!!
