Welcome to 3/ 4 blue where we share photos, videos and information of the exciting and fun things we have been learning about in school!
We made different types of rock out of chocolate explaining the process.
Sedimentary rocks are formed when layers of sediment compress together and it solidifies. Here we used layers of grated white and milk chocolate to represent the sediment. We compressed the chocolate into a piece of cling film.
The heat from nearby magma and pressure from the earth changes the rock. Here we warmed up the chocolate by squeezing it with our hands.
Igneous rock is formed from volcano magma. When it has finally cooled, it becomes igneous rock. Here we used hot water to represent the magma and let it cool for half an hour before unravelling our cling film and having a close and careful look at our igneous chocolate rock!
