In this learning activity you'll locate the countries of Central America on a map.

Learners review the names of the capital cities of the seven Central American countries and locate the cities on a map.

In this animated activity, students view a step-by-step approach for how to connect an ammeter to a circuit. A brief quiz concludes the lesson.

In this learning activity you'll examine the terms associated with a grouped frequency distribution and follows the steps to construct a grouped frequency distribution using manual methods.

Students read about five countries in Southern Africa and locate them on a map.

Learners solve two sample problems for a numerical reasoning assessment.

Students follow step-by-step directions for entering data into a spreadsheet and reporting the results.

Students determine what happens to current flow in a series circuit when the resistance is changed. A brief quiz concludes the activity.

Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.

Learners examine the relationship of voltage, current, and resistance as it applies to vehicle electrical systems.

Learners follow the steps required to construct an ungrouped frequency distribution using either manual methods or a spreadsheet.

Learners read the definitions of various water forms and locate the bodies of water on a map.

Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.

Students examine an Excel spreadsheet to determine range, class, and width.

In this learning activity you'll read introduction to electrical quantities, units, and symbols and test their knowledge in a matching exercise.

Students read about South Africa and the countries that surround it. They test their knowledge in a map exercise.

In part 2 of this series, learners follow the steps of the “mathemagician” to examine these numerical curiosities: The 189 Challenge; An Armstrong Number: What’s Special About 153? Is 495 Different or Indifferent? Is 6174 Different or Indifferent? It is always 618, and Beginning and Ending the Same.

In this interactive and animated object, learners examine Midtronics hand-held battery and charging system testers and view the operation of these testers in an automotive repair facility.

In this animated activity, learners examine the difference between opens and shorts in an electrical circuit. A brief quiz completes the object.
