                                                                            Chemistry Strand


HS-PS1-6. Design ways to control the extent of a reaction at equilibrium (relative amount of products to reactants) by altering various conditions using Le Chatelier’s principle. Make arguments based on kinetic molecular theory to account for how altering condition would affect the forward and reverse rates of the reaction until a new equilibrium is established.*

• Clarification Statements:
  • Conditions that can be altered to affect the extent of a reaction include temperature, pressure, and concentrations of reactants.
  • Conditions that can be altered to affect the rates of a reaction include temperature, pressure, concentrations of reactants, agitation, particle size, surface area, and addition of a catalyst.
• State Assessment Boundaries:
  • Calculations of equilibrium constants or concentrations are not expected in state assessment.
  • State assessment will be limited to simple reactions in which there are only two reactants and to specifying the change in only one variable at a time.

                                                          Applied Water Technologies Strand

1. Demonstrate practices related to Drinking Water Treatment.
   1. Describe the purpose and importance of drinking-water treatment.
      
   2. Identify sources of drinking water in Massachusetts and elaborate on the importance of water-supply protection (e.g. ground water and surface water).
   3. Describe the processes used in a typical drinking water treatment facility (e.g. coagulation, flocculation, filtration, taste & odor control, disinfection, and fluoridation).
   4. Conduct water sampling and collection (e.g. microbiological, lead, copper, organics, radiological).
   5. Conduct laboratory procedures related to drinking water analysis and treatment (e.g. turbidity, chlorine, ammonia, iron, manganese, taste/odor, and algae/bacteria).

                                     Environmental Sampling & Laboratory Services Strand

1.  Conduct environmental laboratory analysis.
   1. Implement laboratory record keeping techniques for specific situations according to current industry standards.
   2. Conduct microbiological testing (e.g. total coliform, fecal coliform).
   3. Use, maintain and calibrate environmental bench top sampling meters (e.g. pH, DO, specific conductivity, and spectrophotometers).
   4. Measure, contain, and mix substances using common laboratory equipment (e.g. balances, pipettes, volumetric flasks). 
      

2.F.02     Performance Example:

• Conduct environmental laboratory analyses and tests using common laboratory equipment (e.g. balances, pipette, volumetric flask, water quality test kits, etc.).

Prepare solutions of a specific concentration by diluting solutions of known concentrations.
