In these two weeks we have received five new students to our class. Welcome to Neuse Charter School!
We are continuing to study the properties of minerals and will shortly move on to the Rock Cycle. On Monday we tested our rocks aquamarine, emerald, mica, fool's gold, and quartz for their hardness on the Mohs scale by using a copper penny. If the copper scratched the rock then it had a hardness scale of less than 3.5. On Tuesday we will continue our student inquiry by examining cleavage, fracture, density, and so on. Our Rock Cycle unit will begin with igneous or volcanic rock and we will compare and contrast intrusive (in the volcano) and extrusive (outside the volcano) igneous rock. Our study will lead us to examine common igneous rocks such as granite, pumice, obsidian, and basalt. Students will observe crystals, holes, among other things to determine if the rocks formed inside or outside of a volcano.
Homework for the week:
Monday: Pg. 451 Review #2,3,4,5
Tuesday: pg. 451 Review #1, Reflect #2, 3,4
Wednesday: pg. 464 Review #1-3, Reflect #1
Thursday: finish the Venn Diagram of intrusive and extrusive igneous rocks (if not already finished)
