Year 3 (Class 9) - Science / Oracy - Gas and Weight

In science this week, we investigated whether gas weighs anything. We shared our ideas giving examples from previous investigations, life experiences and our own knowledge.

Then we weighed a bottle of fizzy water. We discussed what happens when you shake fizzy drinks before opening.  We then did exactly that! We could hear the gas escaping and when we weighed it, the bottle of water weighed less.

This proved that the gas must have weighed something when it was in the bottle.

We discussed what we had observed and used reasons to back up our ideas.
