The learner will understand how to use a cause and effect diagram to find the root cause of a problem.

In this learning activity you'll explore how finding and understanding the root cause of stressors can help reduce stress in your life.

Learners click on the root word of a medical term in the left-hand column and drag it to its definition in the right-hand column. There is a time limit, so students will need to train themselves to recognize these root words quickly. Students may repeat the activity as often as they wish. A total of 74 terms are given in random order.

Learners view the steps for determining the square root of a complex number in Excel.

Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.

In this learning activity you'll be introduced to the cause and effect diagram.

Students read step-by-step instructions for determining the square root of a number using the TI-86 calculator.

Students identify the enamel, cementum, cementoenamel junction, clinical crown, clinical root, and epithelial attachment of a tooth.

Students locate the enamel, cementum, cementoenamel junction, the anatomic crown, and the root of a tooth in this interactive lesson.

In this learning activity you'll simplify square roots involving the product of a numeric and variable term.

In this interactive and animated object, learners examine open and closed head injuries and the common causes and symptoms related to them.

Students read about the three categories of interest groups: Economic, grass roots and community-based, and civil and constitutional rights.

In this interactive object, the learner examines the causes, symptoms, and risk factors associated with a stroke. The terms "thrombus," "emboli," and "hemorrhage" are defined. A self-assessment of risk factors completes the activity.

Learners examine the factors that contribute to hip fractures including osteoarthritis, osteoporosis, and osteomalacia.

In this interactive object, the learner matches various disorders to the acid-base disturbances they cause.

Learners examine the speed control circuits in a DC variable speed drive that cause the RPM of a motor to vary. This activity has audio content.

Learners consider the changes inside a series motor that could cause it to break apart if the load was disconnected. A quiz completes the activity.

The learner will explore the challenges commonly faced with remaining motivated and identify the obstacles that cause a loss of motivation.

This learning activity uses a water pressure analogy to present the concept that voltage pressure is required to cause current flow.

In this animated activity, learners examine the firing circuits in a DC variable speed drive. The circuits cause the current flow through the armature and rpm to vary. This activity has audio content.
