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

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.

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 explore how finding and understanding the root cause of stressors can help reduce stress in your life.

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

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

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.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

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

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.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

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

The learner will understand how to properly use a fillet gage to measure weld size.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

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.

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.
