Last week we were given a presentation by Massoud Robatian, a geologist from INAC. He showed us all kinds of rocks, minerals and gemstones that are found here on Baffin Island.
We learned about the Moh Scale, which determines the hardness of minerals, and also the Crystal Systems which indicate the different shapes of minerals and how they form. Massoud taught us the difference between minerals and rocks, as well as, what characteristics classify a gemstone. The magnetic rocks were really interesting. We were all impressed that the magnetic pull from a rock could be so strong! We were told how the different elements on the periodic table influenced the colours of minerals and gemstones, and how different combinations of elements created such a wide varitey of rocks.
We used loops to inspect the rocks and minerals closely.
Learning about the gemstones is benificial because next semester well will be learning how to set stones in our jewellery and metalwork.

The presentation was very educational and fun. Thanks Massoud!
Beautiful...Diamonds and Sapphires galore...I was reading that Baffin Island is full of gems (besides the ones in your class!). It seems the mining companies are set to pillage. Looking forward to seeing some of the work you have started since 2010 is already here!
