Recreational Mathematics: Palindromes in Mathematics and the Search for Patterns
Users study a chart containing numbers 1 to 99 and look for trivial palindromes as well as double and triple iteration palindromes. The reverse and add technique is demonstrated.
In this animated object, learners examine the ratio control method used in automation when two or more ingredients are mixed. A brief quiz completes the activity.
Learners read about the different uses of the word "data." They will test themselves on examples of data that is singular, plural, qualitative, quantitative, nominal, ordinal, interval, rational, discrete, or continuous.
Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.
Interpreting Engineering Drawings: Common Abbreviations
In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.
In this interactive learning activity, learners review the terms used to describe relative position of body parts in order to have a common set of words to describe their position. Check out our video on relative position: https://bit.ly/2kTXujp
Learners examine the various classifications of airspace and the requirements to pilot an aircraft there. A quiz completes the activity. This object has sound.
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
In this learning activity you'll list three decisions and the methods you used when making your decisions. You'll also learn about decision making methods.
In this interactive object, learners examine sectional views used in engineering drawings. The sections shown are full, half, offset, aligned, revolved, and broken-out. Learners match drawings of sectional views with the names of the views.
