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.

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

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

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

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

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.

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

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

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

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

Learners read a description of torque and study the factors that cause its magnitude to change.

In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.

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.

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 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 view animations showing how to change the connections to cause a DC motor to reverse its rotation. A short quiz completes the activity.
