HOMEWORK: CALCULATE YOUR OWN DENSITY. D = M/V

DO NOW: GIVE EXAMPLES OF CONVECTION, CONDUCTION, AND RADIATION

AIMS:REVIEW CONCEPTS OF SCIENTIFIC MEASUREMENT, HEAT TRANSFER, AND ATOMIC STRUCTURE.

LESSON STEPS1. SILENTLY COMPLETE DO NOW AND COPY

HOMEWORK.2. REVIEW LESSON STEPS3. DISCUSS DO NOW4. NEWS: BINDERS, MIDTERMS5. ATOM MODEL NOTES: 10 PTS, DUE TODAY

OR MONDAY6. DISCUSS/ BEGIN HOMEWORK.

SCIENTIFIC MEASUREMENT: METRIC SYSTEM, DENSITY

HEAT TRANSFER! CONVECTION, CONDUCTION, RADIATION, MOLECULE MOVEMENT, PHASE (STATE) CHANGES...

ATOMIC STRUCTURE- JUST A LITTLE BIT. “CURRICULUM CRAFTERS...”

CALCULATE YOUR OWN DENSITY. DENSITY = MASS/ VOLUME MASS : USE POUNDS. VOLUME: USE (LENGTH)(WIDTH)(HEIGHT) = ___

INCHES3

EVAN’S DENSITY.... MASS = _162_POUNDS HEIGHT = 6’5” = _77_ inches LENGTH = _14_ inches WIDTH = _5_ inches VOLUME = 5390 INCHES 3

DENSITY = 162 / 5390 = 0.03006 LBS/ IN3

THE PROPERTIES OF THE ATOM ARE DETERMINED BY THE PLACEMENT OF THE ELECTRONS.

ELECTRONS “LIVE” IN “SHELLS” AROUND THE NUCLEUS OF THE ATOM- THESE ARE FAR AWAY FROM THE NUCLEUS! THERE IS A LOT OF EMPTY SPACE IN AN ATOM.

SHELL #1 HOLDS 2 ELECTRONS, THEIR HOMES ARE CALLED 1S1 AND 1S2.
