Students identify the various regions of the human body through video.

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 screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions

Students practice identifying common elements from the periodic table by name or symbol.

In this animated and interactive object, learners examine the structure and functions of granulocytes and agranulocytes. Two exercises complete the activity.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.

In this learning activity you'll explore the difference between mass and weight.

In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.

In this animated object, learners examine the mechanisms for gas exchange among the lungs, blood, and tissues.

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 object, learners compare the mode of action of steroids with the action of amino acid-based hormones.

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.

Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.

By the end of this module, you'll be able to:

- Identify actions that can reduce biosecurity risk

- Develop a biosecurity action plan for a farm

- Select the most cost effective strategies

In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position. Check out our video on relative position: https://bit.ly/2kTXujp

In this screencast, learners examine the bones of the appendicular skeleton.

In this animated activity, sexual reproduction in animals is contrasted with the alternation of generation lifecycle of plants.

Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.

Learners examine the location, structure, and function of the unipolar and multipolar neurons.

Learners examine the structure and function of skin including the production of melanin.

This animated object illustrates the events leading to the migration of phagocytes into areas of tissue damage and/or bacterial presence. Learners view bacterial cell phagocytosis, its subsequent enzymatic digestion, and exocytosis.

In this animated object, learners examine the formation of peptide bonds through dehydration synthesis.

Learners read about the mutations that occurred in plants for the successful transition from an aquatic to a terrestrial existence. The classification of plants is based on these adaptive structures.
