Introduce the units of atomic mass measurement as the Dalton and/or the Atomic mass unit. Relate how atomic mass is a quantitative measurement calculated from the number of atoms of elements in a substance, and the mass of those elements in AMU's. Define and discuss Avogadro's number, the mole, and the number 6.02 X 10^23. Discuss and review why the atomic numbers are not whole numbers but calculated based on the isotopes of the element and the percentage of isotopes for each element. Determine how many grams are contained in one mole of water, using AMU,s listed on the periodic table

Discuss how to measure liquid volume accurately. Display a series of graduated cylinders which would allow volume measurements most precisely . Define and discuss how to measure according to the meniscus formed. Introduce the different thermometers and briefly discuss their units.

Review standard base units for measurement in the SI system. List and discuss prefixes commonly used in lang with the base units. Determine how to measure solid volume, use examples. using a printed work sheet, define meniscus and determine how to report the correct volume from 9 graduated cylinder images containing fluid. Discuss temperature and kinetic energy of molecules, elicit that the temperature is the measure of the average kinetic energy of the molecules, as kinetic energy increases due to heat energy being added, the temperature increases.

Define and discuss a number of physical properties. Define what characterizes a physical property from a chemical property. Discuss what differentiates table salt from softener salt and rock salt, physically and not chemically. Elicit that the particle size is the physical property. Discuss the property of solubility being equal in all three types of salt, as 35.9 g/100 ml of water at standard temperature and pressure. Elicit that the solubility is the same but the rate of solution is different depending on the particle size. Question why the taste would be the same. Define and review density and the density formula.

Practice the correct procedure used to measure mass on a triple beam balance and a double beam dial balanced. Discuss the units to be used and how to obtain the balance. Practice on both types of balances and note the difference in measurement accuracy.

Use example of ice in water. Elicit what system(phase) is shown. Define and outline the homogenous part of the system which includes solid ice, liquid water, and water vapor. Determine that each homogenous part is separated by a physical boundary. Define a phase. Define the following states of matter, solid, liquid and vapor. Discuss the properties and characteristics of each. Differentiate between a gas and a vapor.

Discuss the need for a universal system to report data. Analyze the difference between the English and Metric system, and elicit why the metric system is more easily worked. Discuss 11th and 12 century methods used for measurement, like tip of finger to nose. Define and discuss the base units in the international system. Discuss the unit for time, length, mass and temperature, along with the correct letter designation. Introduce kilo and milli.

Discuss the importance of international data units. Discuss the difference in the English and Metric system. Define and discuss the base units used in the international system (SI). Introduce the need for prefixes and discuss the prefix kilo and milli.

Discuss the states or phases of matter. Determine from a beaker with ice and liquid water and vapor that the system is homogenous. Elicit how each homogeneous part is separated by a physical boundary. Define the term phase as a homogenous part of a system separated from other parts by a physical boundary. Define system.
Expand on the definition of Phase to include properties and composition

Define, discuss, and use examples to outline the difference between qualitative data and quantitative data. Impress that qualitative describes "quality" and quantitative relates "how much". Introduce and discuss the use of the independent variable and the dependent variable in a chemical reaction. Show how the rate of a reaction will change depending on the independent variable. Discuss the importance of a control in a chemical reaction rate determination.
