Mystudentsareincrediblyexcitedatthispointaboutanythingthathastodowithairplanesandflying.Theyareallpositivetheywanttobepilotssomedayandarealreadywantingflyinglessons(remember‐theyareonlyfifth‐graders!).
Stepthree:Teachthesupportingacademicsandtheory.Now,it’stimetointroduceacademics.Honestly,Ihavemypickofsomanytopics,becauseflyingincludessomanydifferentfields.Imeanmystudentsuseanglesandmathinflightplanning,mechanicsandenergyinhowtheengineworks,electricityinalltheequipmentonboardtheplane,andofcourse,aerodynamicsinkeepingtheplaneintheair(tonamejustafew).
I’mgoingtousethisasthefoundationtoteachtheacademicsideofallthetopicsthatareappropriate.Westartwithaerodynamics.Theylearnaboutliftanddrag,makepaperandbalsa‐woodglidersandexperimentbychangingdifferentparts.Theycalculatehowbigthewingsneedtobetocarrymoreweight(jellybeans)andthentrytheirmodelswithbiggerwings.Thenwemoveontothegeometryusedinnavigation.Insteadofdrawinganglesonablanksheetofpaper,ourworkspaceismadeofairplanemaps(freefromtheairport).We’reactuallyplanningpartofthenextflightmystudentswill“take”duringtheirgeographylesson.Suddenly,anglesarealotmoreinteresting.Infact,itturnsoutthatweneedabitoftrigonometrytofigureoutsomethings.
Ofcourse,a10‐yearoldcan’tdotrigonometry,right?Wrong!Theyhavenoideathatit’susuallyforhighschoolandlearnaboutcosinesandtangents.Throughoutthis,I’mgivingthemchancestotalkwiththepilotinclass,sharewhatthey’velearnedwitheachother,andevenplanarealflight.Howcoolisthattoakid?

Ifyouuseaprogramthatisself‐guided(thatis,itguidesyouandyourstudentsthroughitstep‐by‐step),youdon’tneedtobehassledwiththepreparation.That’swhatthisunitisintendedtodoforyouandyourstudents.Thisprogramusesthesecomponentsandmatchesyoureducationalgoalssetbystatestandards.
