This week, we have been learning about rocks, soil and fossils.
On Wednesday, we started to look at a few rocks like slate, sandstone and limestone. Then, we got the stones and looked at them with a magnifying glass. After that, we sketched the rocks really carefully.

Later that day, both of us did some experiments on a few different types of rock. We tested the hardness of the rocks: chalk was the softest and the hardest was granite.

Next, we tested the permeability of each rock. Finally, we put all the rocks in acid, to see if they were made from the bones and shells of dead animals.

After lunch, we looked at different fossils. We learnt about how fossils are made.

Then, we made our own fossils using Play-Doh and plaster of paris.

On Thursday, we went on a walk, and we collected different types of rocks and soils. We used a key to see what rocks we had found.

Next, we shook the soils up with water, to see what they were made up of.

Finally, we put the soil into a funnel with some water, to see which was the best at soaking up water and which was the best at letting it through.
