Talk to the students about prospecting for gold and how many miners were fooled by something that looks a lot like gold called pyrite. The students will work in small groups to compare samples of fool’s gold and real gold. They will use the attached worksheet to document their findings and make a prediction on which sample is the real gold. The class will reconvene to hear which indicators mean gold and which mean fool’s gold to check their prediction. . multispectral imaging. Sophie LEROY. G. . Dislaire. , P. Barnabé, . E. Pirard.
