Minerals
When we visited the Treasures of the Mineral World gallery, we learned about the difference between a rock and a mineral. Minerals usually are one colour and mostly have easy to see crystal shapes like cubes, triangles and needles. A mineral is one material; it's like a single Lego brick. It is different than a rock because a rock is made up of two or more minerals (it's like adding on more Lego bricks). We also learned about features of different minerals and carried out tests to help us identify different minerals. Some tests we performed to identify minerals were: Moh's scale of hardness tests, magnetic tests, light tests (light can pass through it or light makes a rainbow), and streak plate tests (looking for the colour a mineral makes when dragged across a streak plate). Here are some of the minerals that grabbed our curiosity: "Calcite because most samples have really cool needle crystals." - Max "Apophyllite because it's so beautiful and it has sparkly needles." - Harveen "Halite because it is the salt we eat." - Sydney "Millerite because it looks like it has feathers on it." - Liam M. "Rhodochrosite because my mom and me found a lot of it and we've never seen one as cool as we've found the others." -Lexi "Geodes seem cool to me. Geodes are a rock and the cool thing about it is you can flip it onto one side and it just looks like a whole rock. Then you can flip it around and inside it looks super cool. Like crystals inside." -Dexter "Tourmaline because it has beautiful colours." - Jyotsna Learning to Draw To learn how to draw, we sketched some African artifacts in the West Africa Gallery. Some of these artifacts included masks, costumes, jewelry, chairs, benches, sculptures, and pots. An artist guided us through our sketching. She showed us how to sketch without erasing, a new way to hold a pencil, different shading techniques and how to do a quick contour sketch (getting a quick outline of the shapes first before adding in the details). Our instructor said she thought we were amazing artists and a wonderful group of humans!
