In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
In this interactive object, learners review the four types of hypersensitivity and check their knowledge of alternative names, mediators, and various antigens and disease conditions.
Determining Empirical and Molecular Formulas (Screencast)
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
Learners use peripheral vascular assessment data to examine characteristics of these four conditions: peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, and acute arterial occlusion. A matching exercise completes the learning object.
Dietary Manager Training: Digestion and Absorption of Carbohydrates (Screencast)
Learners follow the path of a carbohydrate food from consumption through digestion to absorption into the bloodstream. In a matching exercise, students identify the main type of carbohydrate found in four different foods.
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 animated activity, learners examine the symptoms of four cardiac conditions: coronary artery disease, myocardial infarction, congestive heart failure, and valvular disease.
In this screencast, the student will learn that regardless of the surface onto which a blood droplet is falling, the angle or velocity at which it does so, or the volume of the droplet, there are four distinct phases involved in the reaction of a moving droplet with impact against a surface.
In this learning activity, you will learn what supply chain management is, four main links that make up the supply chain, and explore examples of how effective supply chain management works.
