Year 3 Oak class were learning about igneous, sedimentary and metamorphic rocks today. They made sedimentary rock using layers of icing, chocolate chips and marshmallows. They then wrapped this is cling film to put it under pressure and heat to create metamorphic rock. After slicing this to see the layers they did then eat some of the experiment! https://www.barnbyroadprimary.com/autumn-term-6/
