In this learning activity you'll use a chart and a calculator to find prime numbers 1 and 100.

Students test their skill at converting binary numbers to decimal numbers. Immediate feedback is provided.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.

Learners follow steps to convert numbers from Gray code to binary code. They then view steps to change binary values to Gray code numbers.

Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.

Students read an explanation of the Voltage Divider Rule with complex numbers. Examples are given.

Students read an explanation of "superposition" as a technique for ac circuit analysis. Complex numbers are used.

Students view a demonstration of the Current Divider Rule with the use of complex numbers. Examples are given.

Learn more about debugging including: what it is, why we use it, and what it looks like in action.

Atomic weights are used to convert the mass of a sample into the number of moles of the element in the sample and vice versa. Four examples are provided for practice.

In this learning activity you'll explore what scientific notation is and how it's used to express very large and very small numbers.

Learners distinguish between competencies that are effective and robust, and those that are ineffective and weak. The learning object is designed for faculty who are writing or revising courses. It contains audio.

As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.

This primer introduces the student to the correct method of entering complex numbers into a TI-86 calculator.

At the end of this lesson you will be able to

- Explain what biosecurity means.

- Describe why biosecurity is important.

- Identify what kinds of disease agents we try to prevent or control with biosecurity.

- Demonstrate disease agent-host-environmental interactions that result in disease.

In this learning activity you'll discover what the .NET Framework is, what problems it solves, and how it came to be.

The learner reads about the kinds of questions that are most effective to use on student questionnaires evaluating instruction. Generic evaluations are less helpful than evaluations focused on the specific types of instruction and learning expected in a content area. Sample questions are provided.

Learners study an animation that shows how a battery charge reduces over time and when varying resistance values are placed in a series circuit. Ten review questions complete the activity.
