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

Learners listen to an explanation of how to perform an inventory of a farm business. They then list their hard assets and human resources by completing worksheets that they save to their personal computers.

Students view diagrams of nails and read the client's nail history. They then determine if the affected nail has a disease or a disorder and recommend salon treatment and home care.

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.

In this interactive and animated object, learners examine the action of insulin and other antidiabetic medications. In a drag-and-drop exercise, learners match oral agents with the action they perform. In a separate activity, learners answer questions about the onset of action for different types of insulin.

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.
