Students perform conversions among fractions, decimals, and percentages in this assessment.

Play this game to challenge your friends on their knowledge of developmentally appropriate and inappropriate practices in early childhood education.

In this learning activity you'll be introduced to the eight most common logical fallacies commonly used in persuasive speeches.

In this activity we’ll explain what a title block is and how to read the information it holds.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

Robotic welding is revolutionizing welder safety, efficiency, and technique. Knowing how to program a robotic welder is key in this ever-changing industry. In this module you’ll explore what Through-Arc Seam Tracking (TAST) is, discover how it works, and see it applied on the job.

In this learning activity you'll review the operation of an Exclusive-NOR gate by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.

Practice how to make research decisions using the 3 Rs.

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls and unconditional jumps in this learning activity.

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 screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.

This video illustrates what can happen in a court room when chain-of-custody procedures for collecting evidence are either ignored or not carried out properly.

This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.

In this learning activity you'll define and explain the broad steps in achieving quality in an organization.

Formulas and Functions in Microsoft Excel

A learning object to illustrate the right way to enter formulas and functions in Excel.

Learners review office processes to find ways to save time.

You’ll explore how to use Touch Sensing to do a one directional search with a Fanuc Robot and offset of the robot’s programmed path.

We’ll explore touch sense fundamentals, touch sense commands, and break down a touch sense program.

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using calls and unconditional jumps in this learning activity.

Visualizes direction and quantity of glass particles as the glass is impacted by a force.
