In class we were assigned to take notes on rocks and minerals. We had to say how they form, what types of rocks are there (igneous, metamorphic, and sedimentary), the most precious mineral, three rock or minerals and give some interesting facts about them, and so on. What I think that the most interesting thing that I learned was about the mineral and most precious metal, rhodium. I learned that it costs about $10,000 per ounce! that is less than a pound! Also it goes from 5-25 times more expensive and costly than gold! Rhodium is very shiny and they use it on diamonds to make them look bigger, it has this effect because it is very shiny and that makes it hard to see where the diamond ends and the metal begins. Also it was discovered by William Hyde Wollaston in 1803. I also found out about how to identify a mineral, it has to be solid, naturally occurring, inorganic, and has to have a crystalline structure. I also learned that igneous rocks and hardened lava and that sedimentary rocks form from weathering and the remains of other rocks. Also metamorphic rock is altered under heat and pressure and there is more heat and pressure the closer you get to the core and that is usually where they form. Also diamonds form under ground because they need heat and pressure to form and that is why they cost so much, is because they have to dig deep to find them. The most precious mineral is carbon in diamond form. Diamonds also conduct heat really well! Also diamonds, they have the highest melting point it is 3550 degrease Celsius! I took many more notes, these are just some
-Mrs. M if your reading this I just want to let you know that when doing this I left my notebook at school , this is all based on what I remember!!!

At school we had a volcano project where we had to study a specific volcano and we also had partners, my partners were Mira and Maryam. I think that we did pretty well, we had a good video with many interesting facts about Mt. Vesuvius. I think that our presentation was not missing anything, except maybe we could have made it a little more serious than funny. I think that for our grade that we should get a 5/6 because I think that we do not deserve a 6 because our actual talking par6t in front of the class rather than the video was a little but unrehearsed. What I learned about volcanoes is that there are different types and that Mt. St. Helen is not in Europe, but in the state Washington. The affect people who live near them because usually volcanoes bring good tourism and also fertile soil around volcanoes. They affect the world because when a volcano erupts there is ash in the air and then people cqn not fly there or fly through it so then people can not travel through that rout.
