Hi 3J,
This week in Science we continued our topic of Rocks, Soils and Fossils.
We tested the properties of Marble, Slate, Granite, Gabbro, Chalk and Sandstone.
By trying to scratch into these stones using a copper coin, we tested the durability.
When we placed the rocks into a tub of water, we could see if the rock had a high density (it sank) or a low density (it floated).
We also tried pouring water onto the rocks to see if the water would pass through. Water passed through none of them and we found they were NOT permiable.
Finally, we made observations about the feel and texture of the rocks.
Find some rocks in your garden, local park or green space. Make sure you give them a good clean before using them in our investigation!
Test their properties like we did in class.
You can ask yourself the questions:
- Do they float or sink? (High or low density)
- Do they let water pass through them? (Permiability)
- Do they break easily? (Durability)
Share your finds with us in the comments please.
Next week we will be learning about fossils and retelling the rare and fascinating process of fossilisation.
See you soon, Geologists!
