Oncethe muscles are compromised, the creature is challenging to control. As an example, the syringes had to bereset frequently on leaking muscles because the air volume in the system would slowly decrease.Furthermore, actuating the syringes rapidly can be fairly exhausting for the operator after a while due to theamount of friction caused by this. The silicone tubing also can cause issues, specifically withmaneuverability, because the weight and elastic force caused by the tubes can affect the movement of thecreature.(b) Prototype ActuationBefore production of the McKibben creature, each team must first

Figure 2:Student responses to the questions "How would you rate the effectiveness of your group's teamwork?"

It is unclear, whether successful students were more likely to have good teamwork andcommunication or whether the students that were unsuccessful rated themselves poorly becauseof the failed attempt in the escape room. Questions about their anticipated teamwork andcommunication before realizing the result of the escape room could
the ability of desk-scale experiments to teachimportant concepts on process safety that cannot be easily accomplished with pilot-scalelaboratory equipment. Students also obtained characteristic curves for pinch valves at variouselevations of the feed tank with respect to the valve position (b). This allowed students to learnimportant relationships between the valve flow coefficient and valve openness percentage in asimplified fashion by tuning the valve openness percentage. Valve characteristic curves were alsocompared to those provided by valve manufacturers, establishing differences with other valvescommonly used in practical applications.Characteristic curves of centrifugal and diaphragm pumps (a) demonstrated that desk-scaleexperiments

To run avirtual experiment, students must set up the system first, then turn on the pumps and adjustthe flow using the inverter dial.

engineering curriculum and (b) expecting laboratory instructorsto assess thirteen different learning outcomes for student success is unrealistic.Therefore, a survey was designed to gain an understanding of the outcomes most important to thevarious lab stakeholders (faculty, non-academic engineers, and students) and the currentsuccesses and gaps of chemical engineering laboratory curricula in addressing those outcomes.This paper describes responses received from chemical engineering students. Including thestudent voice is important in higher education curricular development and can have positiveoutcomes in terms of student perceptions of courses and their engagement in them [2].Additionally, students are more intrinsically motivated by course

A digitalimage is made up of pixels, and each color is a combination of RGB channels. Any point with anintensity for each of the RGB channels is proportional to the light absorbed/transmitted by thesamples.Figure 1.
