FAB-U-LOUS FRIDAY!!! Get out page 10 Cornell Notes for me to check Get out page 8 Determination of the Density of Pennies LAB to turn in You need a writing utensil that is DIFFERENT COLOR from the one you used to write your Cornell Notes EVERYTHING ELSE ON THE FLOOR!!! Lab fee or paper towels anyone?????
Solid, Liquid & Gas Cards
SolidLiquidGasPlasma Shape X Volume X Compressibility X Def. Incomp. Indef. Def. Incomp. Indef. Comp.
Physical Property A quality of a substance observed without changing the substance’s composition. Color Density Melting point Solubility (if it dissolves)
Chemical Property The ability of a substance to undergo a chemical reaction and to form a new substance Rusting Combustion Flammability
Extensive physical properties Physical properties of matter that depend on the amount of that chemical Mass Volume Length Shape
Intensive physical properties Physical property of matter that DOES NOT depend on the amount of that chemical Color Melting point Density
Properties of Matter Cards
MANIC MONDAY 9/8 Get out any late papers to turn in: Density penny lab Graphing WS Cornell Notes Any lab fees/Kleenex/paper towels? Did you grab the pages on the way in the door?
Physical Change A change which alters a given material without changing its composition nothing new is created A + B AB
Physical Change Physical Changes Any phase/state change Dissolving of a solid Crushing of a solid – change in size/shape Thermal pollution (temp of lake rises killing fish)
Chemical Change aka (Chemical Reaction) Change that occurs when one or more substances change into new substances A + B Q
Chemical Change Rusting of iron Photosynthesis Digestion Combustion
Chemical Change Clues that a chemical reaction is occurring: Energy is absorbed / given off (heat or light) Change in color or odor Production of a gas or solid from a liquid Not easily reversible Something NEW produced that does NOT look like the starting reactants A + B Q !!!
