1. Student groups (6-8 members) independently conduct four
different experiments using water channels based on the advice
and instruction by faculties and teaching assistant. Students canalso decide experimental conditions by their ideas.
2. Before the experiment, students make a preparation reportson the each type of experiment, and understand thefundamental theory of hydraulics via interview by faculties prior
to the experiment.
3. After the experiment, students prepare the reports on theexperimental results and analyses, and obtain the deeper
understanding on the hydraulics via the interview by faculties
after the experiment.
4. In the last class, students construct PET bottle rocket basedon theory in hydrodynamics, and perform the flight contest.
5. Through this course, students obtain skills and abilities suchas originality (e.g., presentation based on their creativities),
collaboration ability (e.g., creation via the group collaboration),and competitiveness (e.g, contest-type competition).

In the experiments on hydraulics, students obtain a deeper
understanding on fundamental principles regarding water flowwhich have been studied in lectures on hydraulics. The fourdifferent experiments were conducted, namely (i) water flow inpipe line, (ii) water flow in open channel, (iii) water flow on theweir and (iv) water wave. In the last class, students have the PET
bottle rocket contest, where students design and create their
original rockets based on the fluid dynamics. In this class,performance of student is evaluated by three activities: (i)“interview prior to experiment” where background knowledge on
hydraulics is checked if the students already have an sufficientknowledge to conduct the experiment, (ii) “experiment” wherestudent’s attitude and leadership is considered during theobservation and measurement of various phenomena relevant towater flow and (iii) “interview after the experiment” wherestudent’s understanding on the experimental results and analysis
is evaluated.

In the PET bottle rocket contest, unique rockets were proposed from eachgroups. Follows are representative rocket and their characteristics.
(1) Two-stage rocket• Two parts of rocket (upper and lower parts) were made and connected.
After the launching, these parts separated off in the sky and the upperparts kept flying after the separation.
• Characteristics of rocket body are (i) connection parts composed ofgarden strong tube, (ii) wing attached backward and (iii) setting thegravity center forward.
(2) Rocket with higher flight stability• Characteristics of rocket are (i) shorter rocket body length to lower thetorque effect working on the front and back part of the rocket body, (ii)setting the gravity center in the middle of rocket body and (iii) adding therotation of body around the central axis, to improve the flight stability㧗Ᏻᐃᛶ䝻䜿䝑䝖䠄㔜ᚰ䛾☜ㄆ䠅ὶయຊᏛ䛻ᇶ䛵䛟㣕⾜ィ⟬
