In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.
The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.
In this animated learning object, students examine the life cycles of a virus.
In this learning activity you'll assembles parts of a virus and match virus terms and descriptions.
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Vapor pressure is the pressure exerted by molecules in the gas phase in equilibrium with a liquid or a solid. Two examples are used to illustrate vapor pressure: the drying of clothes and the evaporation of ice.
In this learning activity you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.
In this animated and interactive object, learners follow two rules to write unit conversion fractions.
Students review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each. A quiz completes the object.
In this animated object, students observe how ATP energy is used to move substances across the cell membrane from an area of lower concentration to an area of higher concentration and when something too large needs to get in or out of a cell.
In this learning activity you'll review the structure and function of the different tissues of the human body.
In this animated object, learners examine how thermal energy is transferred by conduction, convection, and radiation. A brief quiz completes the activity.
In this animated and interactive object, learners examine the lifecycle of fungi including asexual and sexual reproduction. Learners test their knowledge by identifying a diagram and by completing a crossword puzzle.
Learners read a brief description of the vertebral column and examine the distinctive features of the cervical, thoracic, and lumbar vertebrae.
Learners play a vascular system "game" to identify the arteries, capillaries, and veins that make up the renal blood supply pathway. A score is given at the end of the activity.
In this animated object, learners examine the function and location of the motor neurons and the damage that can result when they are injured.
Learners examine the location, structure, and function of the unipolar and multipolar neurons.
In this interactive object, learners examine the neuron pathway into and out of the spinal cord. They complete the activity by testing their knowledge of vocabulary and the location of spinal cord structures.
In this animated and interactive object, learners examine the properties of liquids, solids, and gases.
In this animated object, learners examine the various connective tissue layers of the muscle organ. The terms "prime mover," "synergist," "antagonist," "origin," and "insertion" are defined.
Students examine atomic structure and the octet rule.
In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.
In this well-illustrated object, learners examine the structures and properties of the four types of solids: molecular, metallic, ionic, and covalent network. Five interactive questions are provided.
In this interactive object, learners examine the structure and function of the sense of taste.
In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.
