Rocks in 5th and 6th

The Rock Cycle – Investigating how rocks are formed

During the first lesson 5th and 6th class learned about the layers of the earth and how rock can both be in the form of a liquid and solid. For the next lesson we focused on the rock life cycle and we carried out three experiments using sweets. The first experiment represented sedimentary rock. We combined all the sediment (sweets) using pressure. Next we formed metamorphic rock by heating the sweets using a dryer and adding more pressure. Finally, we formed igneous rock by putting the sweets into the microwave and leaving the sweets to harden overnight.

Erupting Volcanoes

5th and 6th class were learning about the different parts of a volcano and what causes them to erupt. We designed volcanoes using the paper maiche method to form the structure. Then they explored how chemical reactions occur by mixing vinegar and baking soda. We had lots of fun making these!
