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

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

In this interactive object, learners read the definitions of terms associated with the construction of a grouped frequency distribution. A brief quiz completes the activity.

In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied.

In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.

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.

In this learning module, you'll explore what electrical grounding is, how it works, and some real-world applications.

Learners test their knowledge of the framework of the U.S. government in this 13-question quiz.

Students locate the seven countries in the Sahel region, which is between the Sahara and the coastal rain forests. They identify the famous city of Timbuktu in a map exercise.

In this learning activity you'll discover different cultural traditions between East Asian people and North Americans.

In this animated activity, students read about the two general types of variable resistors: potentiometers and rheostats. A brief quiz completes the learning object.

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

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

In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.

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

Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.

Learners follow steps to establish class boundaries and tally the data using a spreadsheet.

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

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