Two Liter Boat Activity
Transportation Systems Boat Research Assignment
2a. Explain the history, economic, social, and technological impacts of marine transportation on our environment (part of their textbook homework). 2b. Explain marine terminology using diagrams distributed on student handout sheets.
What Students Do
Record the author, title of book or magazine, title of article, magazine date, and copy an article or sign out a book or magazine pertaining to the research on marine transportation for further research. Emphasis should be on researching one form of marine transportation. Copies of the articles are submitted with the report. Record and copy any Internet web documents. Students also investigate marine transportation past and present, transportation innovations, marine products, canal systems, cargo transportation, yacht races, economic impacts, and social impacts. They investigate the impacts of marine transportation on the environment and the development of boats, canal systems, products for the present. Write a one page report on the articles researched explaining what was discovered, and how it will help to design the two liter boat. Copies of the articles are submitted with the report. Talk to family members, other students, and teachers about the project, ask for help and ideas in creating the design. Select and use appropriate materials, equipment, and tools and learn to optimize or use tradeoffs when building the boat. Students are expected to work effectively on task in a lab, cooperate with fellow students and teachers, and present their findings in a written summary and on videotape, using the design brief explaining the activity, size specifications, materials available for scale model, materials available for the boat, evaluation criteria, procedures, due date, textbook homework, and worksheets. Use computer aided design drawing programs to draw their boat orthographic projection of students have experience on CADD systems available, or show interest in drawing their boat on a CADD program. Sketch small pictorials of complex parts that may be difficult to show in an orthographic projection. Use rulers and traditional drafting tools to produce scaled orthographic projection drawings, one inch to a foot (1"=1) scale model of the boat from the drawing, using two inch pieces of straws to simulate the bottles, wood strips to simulate 2 x 4s and oars, window screen to simulate chicken wire to secure bottles, small pieces of wire to simulate plastic ties to hold chicken wire, and masking tape to simulate duct tape. The scale model and the blueprints or CADD drawings will be evaluated on the evaluation sheet. Complete a bill of materials needed, showing all parts, and quantities on the 17" x 22" graph paper. Search the Internet for boat information. Engineering design is evident when students search the Internet for information for boat designs, develop drawings, build a model, and evaluate it. Obtain materials provided to or items found at home Design and material changes to improve the boat are encouraged. Begin processing materials and constructing the vehicle. Attach bottles to the wood frame. Be careful of the chicken wire. Use science, math, and technology skills to produce a boat, and prepare a summary report illustrating skills in each of those areas. Interdisciplinary areas that will be understood and utilized are analyzing drag, buoyancy, material processing, design drawings, and choosing the best parts and materials for the optimal solution. Make necessary adjustments during construction. Keep a daily log of work on prepared daily log sheets and sketch ideas. Explain the operation of the boat in a summary report and videotape explaining how their boat performed and if the boat worked as planned. By testing the boats in the swimming pool, students will understand mechanical advantage when designing oars, oar locks, and location, forces of drag and the affects on the boat efficiency in the water, boat buoyancy, balance, center of gravity, the affects created by the weight of passenger and boat. Discuss advantages and disadvantages of the boat design with the teacher and teammates to improve efficiency. |
