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 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.

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

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

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

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

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

The learner will explore the techniques used to identify cause-and-effect relationships of a particular problem.

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

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

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