Fluids
A Concept Builder is an interactive questioning module that presents learners with carefully crafted questions that target various aspects of a concept. Each Concept Builder focuses the learner's attention upon a discrete learning outcome. Questions target that outcome from a variety of angles using multiple difficulty levels or varying activities. The following Concept Builders target concepts associated with Fluids.
Properties of Matter
Learning Goal: To identify the properties of solids, liquids and gases with an emphasis on properties that are most characteristic of fluids.To understand the properties of solids, liquids and gases with an emphasis on properties that are most characteristic of fluids.
Fluid Pressure
Learning Goal: To describe the nature of fluid pressure and to identify the variables that affect the amount of fluid pressure at a given location.
Buoyancy
Learning Goal: To relate the actual weight of an obect to: the apparent weight when fully submerged in water, the buoyant force it experiences, and the amount of water displaced (in L, kg, and N).
Sinking, Floating, and Hanging
Learning Goal: To relate object mass and volume information to the gravity and buoyant force in order to predict whether an object would float, sink, or "hang".
Pascal's Principle
Learning Goal: To use Pascal’s Principle to explain and analyze the operation of a hydraulic lift.
Flow Velocity
Learning Goal: To identify the effect of variations in the cross-sectional area of a flow tube upon the flow velocity for fluid in the flow tube.
Bernoulli's Principle
Learning Goal: To use Bernoulli’s principle (and the principle of continuity) to compare the velocity and the pressure at various locations within a flow tube.
