Weight-Volume Relationships: Saturated Unit Weight
Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.
Weight-Volume Relationships: Introduction to a 3-Phase Diagram
In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.
Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.
Weight- Volume Relationships: Saturated Density (Metric)
Students read how to determine and calculate the saturated density for a given sample of soil or aggregate, based on the mass-volume relationship. Practice problems complete the activity.
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.
Dietary Manager Training: Hydration, Dehydration, and Elderly Clients
Learners read about the role of water, the basic physiology of water balance, and the effects of dehydration particularly on elderly clients. Tips for maintaining proper hydration are presented. In an interactive exercise, students calculate how much fluid a client needs based on his/her age, health, and weight.
