This week in Science Year 3 have been investigating how rocks change over time as part of their Learning Challenge Question: What can rocks tell us about the way the Earth was formed?
They agreed that rocks don’t change massively to the naked eye, however we know that they must change over time somehow!
We worked in small groups to conduct an experiment. We chose a rock, and placed it inside a jar with 100ml of water. We shook the jar to the count of 100, then filtered out the water through filter paper to see what was left behind.
Once all of the water filtered through we noticed there was some debris left in the filter paper. Some of us said that this looked like sand! It was clear that the rocks knocking together had made small fragments break off.
Super work, Year 3!
