as well, as a focal pointof our design was availability and convenience. Thus, we arrived at a prototype that is 1) cheapand easy to build, 2) relatively small and easy to install, 3) interchangeable with most plumbingsystems in bathrooms and kitchens, resizability would also account for this, 4) environmentallyconscious materials. Our device is a water wheel that can be fitted onto many different types ofpipes, and produces a small amount of energy. We believe that with many of these within a buildingwe would be able to generate a reasonable amount of energy for utilization for any purpose.IntroductionToday, people are using electricity more than ever, and as climate change is increasingly creepingup on us, finding new sustainable sources

this topic. Our work addresses this gapby designing a novel immersive technique for visualizing relativistic effects and comparing thistechnique to existing non-immersive methods of instruction.IntroductionAlbert Einstein’s theory of general relativity (GR) is currently the leading theory to explaingravity, one of the four fundamental forces of physics. First proposed in 1915, GR has sincebeen validated by numerous experiments, including the detection of gravitational waves thatcaptured the public’s attention in 2015 [1], [2]. In addition to the significant contribution ofGR to our understanding of the universe, it also finds practical application in our daily livesthrough the GPS that allows us to navigate with our phones. Unfortunately, GR

traditional daytime undergraduate curriculum. By"compressed version," we mean teaching the same program as the daytime undergraduateprogram, with the same level of demand, but in a shorter period and without makingsignificant adaptations to the reality of "working students."At least initially, there exists a perception that generally, only a minority of students enteruniversity driven by intrinsic motivation [1], and an even smaller portion envisions a careeras an academic or researcher [2]. Typically, motivations tend to be more pragmatic,especially acquiring a degree and the necessary learning to gain access to employment orundertaking ventures that allow them to make a living. Working students aim to obtain aprofessional degree that offers them

Educators must ensure that every experiment isdesigned with practical applications in mind and implemented in a safe environment. This aids theinstructors in facilitating critical thinking amongst the learners, ensuring that they can proffersolutions to essential questions.

theteaching and learning of a physics course through the students' perception. The modifiedILD has the same three stages as the original ILD, with two main differences in whoperforms the experiment and when it is performed. Specifically, the three phases in themodified ILD are 1) predict, 2) experiment (by students working in groups, not theinstructor), and 3) reflect (in groups, not individually). The first phase, prediction, beginswith the analysis of a physical situation in which students have to predict the behavior ofthe situation based on the knowledge imparted in the session by the instructor. This occursat the end of the instructor's exposition. The second phase occurs in the laboratory sectionof the course and relates to students' experience

Such efforts include different teachingand learning tools, approaches and modalities [1 - 11]. Students’ quality and instructor’steaching skills also play a role.
