In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
Building Core Abilities During Student Learning Through Formative and Summative Assessment
This learning object gives instructors an opportunity to review the definitions of formative and summative assessment and list examples of the evaluations they use. In a drag and drop exercise, they classify a variety of assessment tools as either formative or summative.
The Formation of Ester Bonds in the Synthesis of Lipids
In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
