Common Types of Oxidation-Reduction Reactions (Screencast)
Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.
In this animated object, learners examine the design of a ladder circuit that provides manual control to a water pumping system. Students also study modifications to the circuit as the complexity of the system increases.
Dietary Manager Training: Cooling Foods Using an Ice Water Bath
In this animated learning object, learners read about the proper handling of foods that contain the nutrients and water that bacteria require for growth.
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.
In this animated object, learners examine the structure and function of intracellular and extracellular fluid. They also read about the most common electrolytes in the body and complete a matching exercise to test their knowledge.
How Adding Parallel Branches Decreases Total Resistance
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.
How Adding Parallel Branches Increases Total Current
In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.
In this interactive object, learners assign water supply fixture units to a water distribution system using Section 82.40 of the Wisconsin Plumbing Code.
Learners read about how universities, government agencies, energy companies, and nanotech firms are working together to use nanotechnology to help produce clean water for consumption.
Plumbing Sizing Activity: Assigning WSFUs and Pipe Size to the Water Distribution System
The learner assigns water supply fixture units and pipe sizes to a water distribution system using the Wisconsin Plumbing Code and a uniform pressure loss worksheet.
Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.
