Overview

• 10th 12th grade
• Students were engaged and excited.
• Students were helping each other through
  cooperative learning.
• Students presentations.

3
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.

4
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.

5
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.

6
Ethics

• Individual accountability.
• Respect each other as a unique individual.
• Joy of success is priceless.

7
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.

8
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.
