Understandings
 Practicing lab safety is foundational to all lab work.
 The SI measurement system is used by scientists worldwide.
 Chemical and physical properties are described using recorded observations and measurements that are both precise and accurate.
 Measurements and observations are analyzed using mathematical processes to discover connections and trends.
 Calculations and analysis are the justification for your results.

Lab Safety and Technique: Students will be able to...... 
 Demonstrate the use of goggles and aprons. Know when to wear them.
 Help one another practice safety, including use of goggles and aprons.
 Use Safety Data Sheets to understand the propertues of substances used in lab and prepare to use those substances safely.
 Work safely in lab, making good decisions.
 Describe the use of each piece of glassware and equipment before using it.
 Ask for a consultation if unsure of a procedure or piece of equipment.
 Demonstrate procedures for weighing, measuring volume, removing a chemical from a stock bottle, pouring solutions, measuring pH with paper and a meter, lighting a Bunsen burner and using it to heat various substances in different vessels, using a hot plate, and appropriate use and care of all lab equipment.
 Keep the work area neat, clean, and safe.

Measurement and Analysis Skils: Students will be able to.... 
 State the prefixes, values, and relative sizes for milli , centi , and kilo to use with the SI units grams, liters, meters as equalities.
 State 5 base (fundamental) SI units used in chemistry and how to use them both in lab and in calculations.
 Measure mass, length, and volume in SI units, with appropriate precision, and record the measurement with the correct significant digits.
 Describe measurements as accurate and/or precise, and explain your reasoning.
 Write a ratio from an equality, express the ratio as a fraction, and use the fraction as a conversion factor.
 Use dimensional analysis to convert between units in problemsolving.
 Use multiple conversion factors in dimensional analysis.
 Use scientific notation (standard form) in calculations for numbers less than as well as greater than 1.
 Use scientific notation to express significant figures in numbers with leading or trailing zeros
 Explain the difference between derived units and fundamental units.
 Describe some derived units used in chemistry (ex. volume, density) and how to use them.
 Define density as a relationshp between the mass and volume of an object or substance.
 Write density as a ratio of mass per unit volume; as a conversion factor
 Use the density formula to find mass or volume of a known or unknown substance.
 Use the units for density as a conversion factor. Use algebra to rearrange the density equation to solve for any of the 3 variables.
 Use dimensional analysis together with mathematical equations to correctly express the solution to a calculation.

Observation, Description, and Analysis of Matter: Students will be able to.... 
 Describe the differences between pure substances, mixtures, solutions, elements, and compounds using the terms heterogeneous and homogeneous.
 Sketch and interpret particle models of pure substances, mixtures, solutions, elements, and compounds.
 Describe each processes of interconversion of states of matter in words and in particles, using a sketch.
 Describe each process of interconversion in terms of energy (thermal) lost or gained.
 Use both element names and symbols for 48 common elements, using periodic table with both names and symbols. List common substances containing some of the elements.
 Three basic laws describe how matter behaves in chemical reactions. List and describe each.
