Rock Investigation

This week, Year 3 took part in a ‘Rock Investigation’ as part of our Rocks, Relics and Rumbles project. They tested different types of rock such as granite, slate, sandstone and chalk to find out whether they were part of the sedimentary, igneous, or metamorphic rock group.

To do this, they checked the samples appearance for crystals, whether they were shiny or dull or if they had holes or fossils in them. They then tested their properties to find out whether they were a hard of soft. They knew that if the knife made a mark on the sample that it was soft and if it didn’t it would be classed as a hard rock. They also used pipettes and water to test if the samples were permeable (meaning they absorb water) or if they were impermeable (meaning waterproof). They then looked through their tables of results and were able to decide which of the 3 groups they belonged to.

The children worked in small groups to do this and really impressed us with their team spirit and enthusiasm throughout. There was definitely a lot of fun had during this investigation!

Great work, Year 3 – have a brilliant weekend!
