He is most famous for his discovery of oxygen (O), but he also discovered laughing gas, was the first to carbonate water and was a pioneer of research into electricity.
Use this video and experiment in your classroom or set as an activity for students to try out at home to explore why eating raw spinach leaves makes your mouth feel chalky.
It’s not just the arts that are creative, chemistry is too. And it’s an essential element in its teaching
Worksheet to develop understanding of the pH scale and apply it in the context of ocean acidification. Extension questions provide more challenge on carbonic acid and acid base equilibrium, leading to a research task on the consequences for marine organisms.
Hone your students’ observation skills by asking them to observe two microscale reactions: neutralising citric acid and creating a lead iodide precipitate
