Year 3 Science - Rocks and Soils

Year 3 have been busy petrologists (rock scientist)  this half term. First, we investigated the properties of a selection of rocks by testing their hardness, appearance, density and finally if they reacted to a drop of weak acid (vinegar). 

We then learnt  about three different rock types and how they form. We used layers of bread to make a sedimentary rock complete with a fossilized sea creature. The class looked at how igneous rock can cool quickly and form obsidian or slowly to form pumice (the only rock that floats).

We also used play-doh to experiment how heat and pressure can change sedimentary and igneous rocks into a new type of rock called metamorphic.
