A popular Earthlearningidea in May was
"The space within - the porosity of rocks; investigating the amount of pore space between the 'grains' of a model 'rock'"
Underground water supplies and reserves of oil and gas depend on the presence of porous rocks, which are capable of holding such fluids in their pore spaces.
The lesson could form part of an investigation in science or in geography, or could be used when pupils are trying to understand why their country has, or lacks, good underground water, oil and gas resources.
Lots more good teaching ideas can be found on our
