MLO1-1 Demonstrate significant figure rules in calculations, using algebraic methods, scientific notation, and rounding numbers.
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
MLO1-3 Evaluate the uncertainty, accuracy, and precision of measurements.
MLO1-4 Explain the key components of the scientific method and differentiate between observations, inferences, and conclusions.
MLO1-5 Differentiate between states (phases) of matter, pure substance or mixture, atoms, elements, compounds and molecules. Differentiate between a mixture that is heterogeneous or homogeneous.
MLO1-6 Categorize properties of matter as being quantitative or qualitative, physical or chemical, extensive or intensive.

How do you use more than one conversion factor? Here, we'll learn how to combine multiple conversion factors into a row so that you can convert units in more than one step using the factor label method or dimensional analysis.

Tyler DeWitt - We'll practice solving density example problems. We'll look at how to use the density number like a conversion factor, to solve for mass or volume. Watch this video after the density introduction or before the more complicated video on density exercises that has unit conversion.
