Activity 2

Problem Solving (Unit Analysis)

Objectives

- - (CLO4). Interpret and utilize mathematical formulas while solving problems
  - (MLO1-1) Utilize algebraic methods, scientific notation, rounding numbers, and significant figure rules in calculations
  - (MLO1-2) Apply units of mass, temperature, time, length, and derived units, such as volume and density using dimensional analysis to solve problems with single or multiple steps or conversions.
    - - Recall the common base SI units of measurement, prefixes, and their associated symbols
