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

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

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.

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

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.

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.

In this animated activity, learners read about the properties of a square and its components. They then work practice problems to find the perimeter and area of squares.

Learners examine how metal detectors function. This object includes animation and sound.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how resistance decreases in a parallel circuit as branches are added.

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

Learners examine how five or six groups of electrons around a central atom cause the shape of the molecule to be trigonal bipyramidal, seesaw, T-shaped, linear, octahedral, square pyramidal, or square planar. Seven examples and three interactive questions are provided in this animated activity.

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 explore how computers connected on a network use Ethernet technology.

The learner examines what it means to listen respectively and how to become a better listener.

In this learning activity you'll play "How to Really Be a Millionaire" to learn the basics of accumulating wealth.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.
