Hybrid Fuel Cell Vehicles Followup Bob Thomas, Stephen Ha, Walter Kondratko IIT RET team This material is based upon work supported by the National Science Foundation under grant No. EEC-0502174. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation.
Overview • 10th – 12th grade • Students were engaged and excited. • Students were helping each other through cooperative learning. • Students’ presentations.
Pretest • Pre-test covered content • How do vehicles generate electricity? • How does vehicle shape affect aerodynamic drag? • Students got most of the concept correct or they made pretty good guesses. • Students have some idea of what a hybrid car is.
Posttest • Posttest covered content - Electrical output can best be supplied by ____ - Factors influencing aerodynamic drag are _____ • Due to the time constraint, a couple of the concepts being asked in the posttest were not able to be discussed or covered. • The force diagram needed to be revised in order for the students to better understand different types of force acting upon a car.
Inquiry • Student will use prior knowledge to respond to questions being asked by the instructor. • During some activities, students will use the internet to help accomplish the goal for each of the activities. • Open-ended activities.
Ethics • Individual accountability. • Respect each other as a unique individual. • Joy of success is priceless.
Engineering Design • Design a Wind Tunnel to test aerodynamic drag. • Design an efficient hybrid car within a budget and weight requirement, or modify the design if necessary.
Recommendations • Adequate materials for the Wind Tunnel activity. - Find a better way to align the fan with the wind tunnel during the test. - Increase the distance of path for the test. - Implement better design to simulate a ram for the wind tunnel. • Modified force diagram is shown on the following page.
