The Effect of Temperature on the Vapor Pressure of a Liquid
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
In this interactive learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.
Stain Measurement & Calculating Angles of Impact (Screencast)
In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).
A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.
Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
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.
Every speech starts with an outline. Knowing how to write one can make the difference between speech success and speech failure. In this module, we’ll explore what’s involved in creating an outline, demonstrate how to put one together, and give you examples you can use to create your own outline.
Writers block happens to all of us. Homework block is even worse. If you’re stuck on how to get started, watch this video to explore how to generate ideas for speeches, papers, and projects quickly and effectively.
In this learning activity you'll explore how port scanning is commonly used by hackers to infiltrate a network and how IT security professionals can detect it.
Learners reflect on their thoughts, feelings, and reactions toward such listening behaviors as interrupting, selective listening, and unresponsive listening.
Calculating Blank Size for Rolled Sheet Metal (Screencast)
In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.
