Rock solid - or not?

Form 4 planned an investigation into the porosity of rock

Form 4 are studying rocks and soils in science. This week they designed and carried out an experiment to see which rock was the most porous.

They decided to either weigh the rocks and measure the difference in mass or measure a set amount of water carefully and see how much was left after 2 days. 

They then conducted some research online about Mary Anning and discovered interesting facts about this famous fossil hunter.
