This teaching resource is a free worksheet about metal ore mining. In the task students carry out a model of metal ore mining by removing the chocolate chips from two brands of cookie and calculating the percentage mass of chocolate chips.
In real life, scientists will test ores to work out the percentage by mass of metal compound the ore contains. The ore will only be mined if the percentage is high enough to make the mining economically viable.
