As part of National Chemistry week some year 7 and 8 groups took part in a more unusual lesson – learning about dry ice. Dry ice is solid carbon dioxide and the groups had fun discovering the interesting and fun properties of dry ice. This included creating bubbles of carbon dioxide using water and washing up liquid, creating a volcano of dry ice bubbles and seeing dry ice cause sodium hydroxide and universal indicator change colour from purple to blue to green and then to yellow proving that carbon dioxide is acidic when dissolved in water! The pupils found the lesson extremely engaging and through the lesson we got lots more students sign up to our new Chemistry Club.
