Year 7 Science Matters!
This week, Year 7 Science classes have been learning about the different states of matter: solids, liquids and gases. The girls have been enjoying themselves by pretending to be particles and arranging themselves as the different states of matter. By playing this game, the girls are using kinaesthetic and visual learning styles to help them understand the topic in a new and interesting way. The girls learnt what happens when a solid turns into a liquid, then a gas and vice versa. An interesting thing that can happen with solid carbon dioxide is that it can change directly into a gas without changing into a liquid first. This is known as sublimation.
When dry ice turns directly from a solid to a gas, it makes for some pretty cool smoke-like effects! The girls conducted a number of experiments with the dry ice, but the best experiment was when the girls were able to make carbon dioxide bubbles they could hold in their hands!
