Monday, October 26, 2009 Mrs. Gall’s Classes

Chemistry Monday, October 26, Warmup: List your 3 resources for research of your science fair topic, including at least one book. Share this with Mrs. Gall for credit today. 2.LCD projector: review of benchmarks as correlated to chapters 1 – 4, focus order; physical and chemical properties and changes, SI system, scientific notation, element vs. compound vs. mixture; continue to make progress on science fair projects. 3.Notes on above, pre-assess existing knowledge and interest/ intrinsic motivation for particular topics. 4.Engage students in creating their own learning goals for this week.

RELEVANT BENCHMARKS C5.2B Distinguish between chemical and physical changes in terms of the properties of the reactants and products. C5.2C Draw pictures to distinguish the relationships between atoms in physical and chemical changes.

RELEVANT BENCHMARKS P4.p2A Distinguish between an element, compound, or mixture based on drawings or formulae. (prerequisite) P4.p2B Identify a pure substance (element or compound) based on unique chemical and physical properties. (prerequisite) P4.p2C Separate mixtures based on the differences in physical properties of the individual components. (prerequisite) P4.p2D Recognize that the properties of a compound differ from those of its individual elements. (prerequisite)

Chemistry Learning Objectives Restated Create, research, and conduct their own science fair experiments. Use scientific notation. Distinguish between an element, compound, and a mixture. Identify and use scientific measurement units (SI/ metric). Distinguish between physical and chemical changes and properties.

Coming Soon: Today: Metric System: notes, reading, homework Tomorrow: Scientific Notation: notes, reading, homework Wednesday: Quiz over Metric System and Scientific Notation Thursday: Science Fair Procedures Friday: Science Fair Procedures

METRIC SYSTEM NOTES 10 POINTS PER SCREEN PG. 12 IN THE TEXTBOOK Each measurement consists of a QUANTITY (number) and a UNIT (label) Example: 24 mL Quantity is 24 Quantity is 24 Unit is mL (milliliters) Unit is mL (milliliters) Qualitative refers to descriptions (color, shape, etc.) Quantitative refers to numerical measurements

Metric system notes pg.2 SI: also known commonly as metric system Page 12, Table 2: 7 base units: length, mass, time, thermodynamic temperature, amount of a substance, electric current, luminous intensity Page 13, Table 3: selected prefixes (kilo, deci, centi, milli, etc) Use unit appropriate for measurement, for example, 1.3 meters instead of millimeters. (another base unit is VOLUME in liters)

Metric System Notes pg.3 CONVERSIONS- see page 13. A conversion factor is a name for the multiplication problem set up to convert one type of unit of measurement into another equivalent one. Example: 1 kg = 1000g Conversion Factor Form: 1 kg/ 1000g Conversion factors are RATIOS (numerator and denominator)

HOMEWORK: PAGE 14 #1-3 DUE TOMORROW 1.Convert each mass to the requested unit g to kilograms g / 1 x 1 kg / 1000g =.765 /1000 kg = kg 2.Convert

Physics Monday, October 26, Warmup: What are the themes of the Mythbusters and the Honda Rube Goldberg machines you’ve seen in our classroom video clips? What are three possible themes you might consider for your RG project? 2.SAMPLE RG DIAGRAM GIVEN; LABELED DIAGRAM VERSION ONE IS DUE TOMORROW. (TODAY FOR E.C.) 3.2nd period: energy transfer and Rube Goldberg Themes. Bring Materials for your machine – will be stored in a closed cardboard box in the classroom for use during class.DUE TOMORROW. (10 PTS FOR ANYTHING TO BE STORED IN THE CLASSROOM FOR USE ON THIS PROJECT)
