Investigating properties of gases as part of our science topic: Solids, Liquids and Gases.
Foxes class have been answering the question: How do we know gas exists?
We weighed a balloon empty and with air in, we made the feather move (as shown here by Felicity) using a fan, we used gas to help us smell products like spices, scented candles and fruit, squeezed the water out of a sponge and had a think about how we know the gas is there? Can you explain these investigations?
