Alchemy Island: Experiments!

Today we carried on our journey through Alchemy Island by experimenting further with the materials found there. We looked at acids and alkalis (and watched  a few explosive videos) and saw how they reacted together using vinegar, lemon juice and bicarbonate of soda. We also looked at which materials were soluble or not using flour, sugar, salt and sand. After that we found out more about how heat change things by burning cotton wool, straw, marshmallows, a leaf and a straw.
