In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.
Automotive Electrical Systems: VAT-40 Starting System Test
In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.
Learners review Ohm's Law and then work 12 problems to help them apply the law to automotive electrical systems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
