Robins class rocks!

Post date: Nov 17, 2017 10:32:05 AM

Over the past 2 weeks we have been looking at rocks and how they form, through a series of fun, interactive (and yummy!) science investigations.

We started by looking at how rocks are formed using starburst!

We chopped the starburst into pieces and used them to make sedimentary 'rocks'. We then rolled and squashed them in our hands to show how metamorphic rocks are formed using heat and pressure. After a short amount of time in the microwave our 'rocks' turned into lava which then cooled into an igneous rock.

We noticed at each stage how the little chunks of starburst 'sediment' got harder to see and then they completely disappeared.

We have also been looking at how fossils form. We made imprint fossils in salt dough using dinosaur bones,

and we fossilised jelly worms in amber (orange jelly!)

Next week we will look at how we group different types of rock
