In this screencast, you'll observe two vehicles moving across the screen at different rates then describe the motion. Additionally, you'll select the corresponding graphs of distance vs. time, velocity vs. time, and acceleration vs. time for each vehicle.
Parts of Speech in Sentences: The Order of Operations
Learners identify the parts of speech by following a certain order until each word in a sentence is labeled. In a variety of exercises, learners practice finding verbs, prepositional phrases, subjects, nouns, pronouns, adjectives, adverbs, and conjunctions.
In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.
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.
