Parameters V and Q would necessarily be expressed in consistentand compatible units. Differences between the two calculated average detention time valuescould then be used as the focal point for an error analysis.The same basic sensor and overflow system can be used to examine other, more complexexperimental systems with the possible intent of comparing actual and theoretical system tracerresponses, determining the system dispersion number, or estimating the extent of dead volumepresent in a system.

Students were asked to demonstrate this knowledge by asking themto transform the graphs given different criteria, such as a change in volume, which is associatedwith amplitude, or a change in pitch, which is related to frequency.RSA Algorithm ActivityIn this activity, one of the most commonly used algorithms for encryption was presented to thestudents. The RSA algorithm uses large prime numbers to encrypt information and is based onthe idea that it is difficult to factor a large number into two prime numbers. Students were firstshown a presentation where they were guided through an example of encrypting informationusing the algorithm. The steps involved in this are shown below and more details can be foundonline4.1. Find two prime numbers p and q
