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.
In this learning activity, learners will reflect on the meaning and impact of stereotypes in both personal relationships and work environments. Identifying behaviors, attitudes, and feelings associated with stereotypes are addressed in this activity.
Phase Relationships Between Line-Neutral and Line-Line Voltages
Learners view a demonstration showing that line-neutral voltages and line-line voltages are not in-phase with each other, but have a definite 30-degree relationship.
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: 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, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.
Learners consider the steps and supplies to use when diapering infants and toddlers. The proper diapering procedure not only meets basic care and sanitation needs but builds relationships and promotes the child’s learning. Brief quizzes complete the learning object.
