This week we went deeper into our inquiry about gas by blowing bubbles after reading a book about how bubbles are formed and why they are always round. We also made soda water by using a soda stream to dissolve carbon dioxide gas in water. We made observations to see the changes in the soda water throughout the day. We had so many questions about gas, so we ask Dr Jeremiah if we could visit the science lab and sent her our questions. The high school students set up some demonstrations which show how to test for oxygen, carbon dioxide and hydrogen. Our favourite was the hydrogen test which made a pop sound!
