Grouping and Classifying

Which rock makes the best roofing material?

Year 3/4 have investigated which rock has the best waterproofing properties for a new school roof. Our fair test using pipettes of water revealed that granite and slate were best. We decided on slate due to it being lighter than granite and less expensive.

GROUPING AND CLASSIFYING ROCKS - Simon's Challenge

In Year 3, we asked the question ‘Which rock would be best to use to create a building that could last over 200 years?’. We carried out a comparable test scratching the rocks by using our nails, a wooden stick and a metal knife, to see what happened to each of our rock types. We discovered that granite was the strongest, as it didn’t loose any particles when scratched, but chalk was far too powdery and pumice far too light.

In Cedar Class, we grouped a selection of rocks based on criteria set by the children.

SEDIMENTARY, METAMORPHIC OR IGNEOUS in Hawthorn Class?

We have observed and analysed cakes and chocolates to investigate if they resemble rocks which are sedimentary - have bits of rock merged together, metamorphic - layers of rock squashed down or changed by heat or igneous rocks which have been melted and are pitted with air holes.

What do you think about a Mars Bar? Sedimentary or metamorphic?

What do you think about Mr Kipling's Angel Slice. Metamorphic or igneous?

What do you think about Malteasers. Igneous or sedimentary?

Following on from grouping rocks, we used a selection of cakes and chocolate to compare the features of igneous, sedimentary and metamorphic rocks.

In Year 3 we used the easi-scopes and iPads to examine a collection of rocks.
