Measurement Conversions , Significant Figures, and Scientific Notation

Monday: Quiz Tuesday over last two columns: Halogens and Noble Gases.
SWBAT: determine the number of significant figures in a measurement.
1.) CALM work for 25 minutes.-Homework if not done.
2.) Test: Classifying Matter, First 2 columns of periodic table, extensive vs. intensive properties, physical vs. chemical changes.
3.) Significant figures intro discussion: Different measurement tools give you different numbers of significant figures. Example: Your hand, a triple beam balance an analytical balance.
3.) Significant Figures lab stations, using image on pg. 67 as an example. 16 stations different measurements followed by worksheet. Go through an example before releasing to stations.
4.) Reading pages 66-67 in the textbook, using

Wednesday: Quiz Friday over Oxygen and Nitrogen Groups.
SWBAT complete: Scientific Notation, Conversion and significant figures calculatio! n problems.
Review: Number of significant figures in numbers practice on the overhead.
1.) Review scientific notation using a table of yes, no, and correct the nonscientific notation problems.
2.) Pgs. 70-71, Read through example problem then students work 5-6, and 7-8.
3.) Go over answers in class from 70-71.
4.) Go over table 3.1, 3.2, 3.3, 3.4, 3.5, and equations on pg. 77. Emphasize the need to understand and memorize table 3.2.
5.) Conversion problem stations. Known unknown and plan.
16 stations where students make conversions at the stations-not made yet.

Friday:
1.) Start with conversions go over a warmup in pairs.
2.) Density Demo with different liquids, water, detergent, oil, alcohol, shampoo,
3.) Density and Temperature Discussion: when to fill up on gasoline, basketballs, tires,
4.) Review scientific notation through density calculation gizmo online.
5.) The n CALM problems.

Tuesday: Goal: Make conversions between scientific units.
1.) Unit prefixes table of notes in notebook.
2.) Go over two examples using dimensional analysis. Dimensional Analysis around the room.
3.) CALM conversions go over volume calculations for CALM.

Thursday
Describe the development of the atomic theory.
1.) Boxes, Measuring Mass, Volume, Density and determine mystery shapes inside of the boxes (lead into atomic theory)
