We will begin the year with the world of chemistry, a fascinating and new subject for students. I will break up Chapter 8 into two sections so it will be easier for students to understand. Students will learn some basics of chemistry such as: the atom, subatomic particles of the atom (nucleus, protons, neutrons, electrons), molecules, compounds, chemical formulas, covalent and ionic bonds, mixtures, physical and chemical changes, solvent, solute, unsaturated, and supersaturated. To understand concepts better, students will fill in a chart with fill in the blank definitions, pictures, and examples of each concept. We will also do a lab to show physical and chemical changes, and a Venn diagram to show their differences. We will do a lab with sweet tea to show unsaturated sweet tea (not so sweet), saturated sweet tea (fairly sweet), and then heated tea with sugar added (supersaturated - very sweet and delicious!). Students will learn that as molecules spread apart, tea can hold a lot of sugar!
Students will receive homework, but it is subject to change depending on how much students have learned in class, and how much they have understood. Tentative homework schedule for the week:
Monday: show parents the Geology test taken before Christmas break
Tuesday: Pg. 213 questions all
Wednesday: finish molecule and compound examples in the chart
Thursday: pg. 227 some questions (depending on the concepts we cover in class)
