Course Learning Outcomes

Demonstrate understanding of theories and application of chemical bonding, qualitative and quantitative descriptions of the states of matter, kinetics, equilibrium, and acid-base chemistry while further developing problem-solving techniques used in chemistry and other scientific disciplines.

Communicate effectively as expected in STEM disciplines through oral and written reports

Demonstrate the ability to work collaboratively as part of a group of 4-5 students in developing a laboratory procedure to meet requirements for a term project

Anticipate, recognize and respond to chemical hazards in the laboratory environment, and as encountered in day-to-day circumstances

Apply scientific methodology and problem-solving skills to chemistry phenomena in a laboratory setting using proper techniques to develop complete experimental records, apply fundamental statistics to the interpretation of experimental results, and draw appropriate conclusions from the analysis of data

Locate, use and analyze information and technology resources
