Introduction to selecting the proper punch and die for air bending or bottoming when forming on a press brake. Includes charts and methods for selection.
In this interactive object, learners experience how the three primary flight controls allow a pilot to determine the motion of the airplane during flight.
In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.
An Algebraic Word Problem Involving Motion: Case 2
In this animated object, learners use an algebraic formula to solve the following problem: An airplane travels a certain distance with the wind in the same amount of time that it takes to travel a shorter distance against the wind. Given a constant wind speed, what is the speed of the plane without a wind?
Learners read about audiological tests including pure tone testing, air conduction, bone conduction, Speech Reception Threshold, and Speech Discrimination Score. They listen to sounds and words recorded at different decibel levels and see a graphic representation of decibel ranges. A brief review concludes the activity.
Students read an explanation of the use of questionnaires in research. Open-ended and closed-ended questions are defined. Students complete the activity by generating a questionnaire.
