After finding out it was a dragon that had vandalised Class 9, Year 4 were given some instructions for how to catch the mischievous serpent. (There is a hidden net underneath the leaves. With all the excitement, we forgot to take a photo!)

Do gases weigh anything?
Class 9 were challenged to see which fizzy drink contained the most amount of carbon dioxide. After weighing the liquid straight from the bottle, the children blew bubbles until all the 'fizz' had disappeared. They then weighed the liquid again before working out the difference. The results showed that Coke had the biggest difference and therefore had the most amount of carbon dioxide.
