Converting Between Standard and Metric Measurements
As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.
In this brief object, learners examine the direct relationship between the volume of a gas sample and the number of moles of gas. A problem is presented so students can test their knowledge of Avogadro's Law.
Adding Fractions With Unlike Denominators (Screencast)
Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.
Conversion Between Mass and Moles of an Element (Screencast)
Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.
In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.
In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.
