1 WHILE THE PILOT IS AWAY  IT’S A DRAG! Lesson 3A

2 TAKE-OFF  Lesson 1A: “While the Pilot Is Away  Where in the World?” WHERE IS OUR PILOT THIS WEEK?

3 Lesson 3A: “While the Pilot Is Away  It’s a Drag!” CRUISE – TRACKING OUR PILOT ’ S JOURNEY IN-CLASS ACTIVITY 1  PILOT TRACKING SHEET – WEEK THREE Let ’ s take a look at how many miles our Pilot has flown during Adopt-A-Pilot! For each leg, use the City-to-City Mileage Chart to calculate how many miles there are between the departure city and the arrival city! Use the 3-Letter City Code Chart to look up the name of each city. Complete the Pilot Tracking Worksheet. Calculate how many miles our Pilot flew this week and add that to the miles flown during week one and week two. Answer the question: How many miles did our Pilot fly during Adopt-A-Pilot? If there is time, we can track our Pilot ’ s flights on

4 TAKE-OFF  THE FORCE OF DRAG When you ride your bike, you experience drag. This is because the air molecules have to move round you and your bike as you ride. The same is true for an airplane! Drag is one of the four forces of flight. It is the force opposite of thrust. Form Drag is due to air molecules having to separate to move around an object. Skin Friction Drag is due to air rubbing along the surface it touches, creating friction. The more streamlined a shape, the less drag it has! Lesson 3A: “ While the Pilot Is Away … It ’ s a Drag! ”

5 Drag is one of the four forces of flight. Let ’ s take a look at this force in action! CRUISE - IT ’ S ALL ABOUT FORM IN-CLASS ACTIVITY 2  HYPOTHESIS: Out of the two clay/Play-Doh © shapes your group created, which piece of clay/Play-Doh © do you think will fall the fastest? (Note: The one that falls the fastest is the most aerodynamic - the one that creates the least amount of drag.) EXPERIMENT: Conduct the experiment as instructed. OBSERVATION: 1. Record how long it took the first shape to fall. 2. Record how long it took the second shape to fall. CONCLUSION: Which shape is more aerodynamic? Was your hypothesis correct?

6 Lesson 3A: “While the Pilot Is Away  It’s a Drag!” LANDING  Congratulations! Today you were an engineer. You discovered more about the force of drag. You used math and geography to track your Pilot ’ s journey. If there is time, our Pilot will ask what you learned while away. Next time our Pilot visits, you will celebrate all that you ’ ve accomplished in Lesson 4: Destinations … Adopt-A-Pilot Graduation Day! If you haven ’ t already, be sure to complete your 3 rd Solo Flight – “ Up, Up and Away ” before our Pilot ’ s next visit. Next Up … Adopt-A-Pilot Graduation!
