Year 3 Put Their Rocks to the Test

After last week’s close-up look at rocks with magnifying glasses, this week Year 3 became geologists. They tested whether rocks were permeable or impermeable by dripping water onto them, scratched and rubbed them to test their durability, and used vinegar to see how each one reacted to acid rain. Some rocks fizzed, some soaked up the water and others barely changed, and the children had plenty to say about why. They compared their results with their predictions along the way.
