Integrated Curriculum Overview There are 2 curriculum units for Principles of Engineering • Semester 1: Bridge Builder • Semester 2: Bombs Away Each unit includes: • Lesson plans for the four academic subject areas and POE • Relevant national standards alignment • Teacher resources (background info, answer keys, rubrics) • Student resources (handouts, worksheets, labs)
Unit Overview • Subunit 1 introduces students to the study of external ballistics and the science and math that governs objects in ballistic trajectories • Subunit 2 lessons examine the history of atmospheric ballistic weapons use in conflicts in the 20th century, including evaluation of the rationale and the ethical issues surrounding the aftermath. • Subunit 3 lessons explore issues associated with ballistic missiles and provide student the opportunity to apply their knowledge in a design challenge
Major Academic Subject Topics and Content • English Language Arts • Biographies • Argumentation and debate • Social Studies • World War II—Battle of Britain, Dresden bombing • Cold War—Cuban Missile Crisis • Science • Physical Science/Physics—Trajectory motion • Mathematics • Quadratic equations • Arcs and chords, basic trigonometry
Ballistic Motion • Ballistics: Study of projectiles, objects propelled by an initial launch force Examples • Sports (football, basketball, baseball, soccer, golf, etc.) • Missiles/Bombs/Bullets • Bullets • Fountains • Fireworks
Do You….? • Drop payload when you are directly above the target • Drop payload before you get to the target? • Drop payload after you’ve passed the target?

Kinematics and Projectile Motion (page 1-11) • Kinematics is the study of the geometry of motion and is used to relate displacement, velocity, acceleration and time without reference to the cause of motion. • Projectile Motion is in two directions – horizontal and vertical • Horizontal motion is independent of vertical motion Basic typical assumptions • Air resistance is negligible • Curvature of the Earth is negligible • Force of gravity is constant at -9.8 m/s2 or -32 ft/s2
h r Analysis of Projectile Motion: Distance • Horizontal Direction (x) represents the range, or distance the projectile travels • Vertical direction (y) represents the altitude, or height, the projectile reaches Calculating Displacement • S = vi t + ½ at2 • Sx = r = vixt + ½ axt2 = vixt • Sy = h = viyt + ½ ayt2 = viyt + ½ gt2
Analysis of Projectile Motion: Velocity • Horizontal velocity (Vx) is constant since there is no acceleration in the horizontal direction • Vertical velocity (Vy) is affected by the gravity; the vertical velocity of a projectile is zero at the height of its trajectory
Analysis of Projectile Motion: Velocity SOH – CAH - TOA
Castle D Altitude 150 m Castle C Altitude 50 m Castle D Knights Altitude 0 m Mountain Matchup It’s time for a fight in the heights. Unfortunately, you don’t have the high ground, but that doesn’t mean you don’t know what you’re doing. The artillery chief has set the cannons at a 76° angle and tells you to fire with an initial velocity of 56 m/s. How long will it take your cannonball to reach the castle? Sy = vyt + ½ a t2 50 m = vyt + ½ (-9.8) t2 50 m = (54.3)t + (-4.9)t2 SOH – CAH – TOA! V0= 56 m/s sin 76° = Opp / Hyp Vy= ? Θ= 76° 0.97 = Vy / 56 Vy = 0.97 x 56 Vy = 54.3 m/s

Bombing Strategies • Tactical Bombing • Targets: Enemy military forces and other military targets and enemy strongholds • Goal: Direct and immediate negative influence on the battlefront • Effect: Direct • Strategic Bombing: • Targets: Infrastructure such as industrial plants, port facilities, and railway bridges, as well as more widespread bombing of an enemy's cities and other civilian-populated areas • Goal: Eliminate the enemy's capability and will to sustain a war effort • Effect: Delayed
Right or Might? • Spanish Civil War • Guernica, 1937 • World War II • London Blitz, 1940-1941 • Pearl Harbor, 1941 • Allied bombing at Dresden, 1945 • Hiroshima and Nagasaki, 1945 • Vietnam • Operation Rolling Thunder, 1965-1968 • Post-Cold War • Kosovo, 1999 • Iraq, 2003
ARE You Convincing? • Assertion: Begin with a statement that describes your main point • The voting age should be lowered to 16 • Reasoning: Follow with the “because” part of an argument where you support the assertion you’ve just made. • Because allowing younger people to vote would increase their involvement in politics and society • Evidence: Support your reasoning with multiple pieces of evidence from multiple unbiased sources • For example, politicians are more likely to listen to what kids have to say if they have a vote
Select one of the conflicts listed to the right (or another conflict your table is familiar with) and debate the following: Was the strategic bombing during this conflict justified?

Build an Adjustable Ballistic Device • Notched Craft Sticks (15) • Glue • Binder Clips (2) • Rubber Bands (4) • Masking Tape • Protractor Catapult should be capable of firing at multiple angles and be mounted on a cardboard base
Test your Trajectories • Set up your catapult • Test your catapult for at least three angles • Do at least 5 trials and average the range for each angle • Using the average data, create a graph illustrating the range of your catapult
Battleship! • Mount your catapult on a “battleship” • Place your battleship on the grid • Each square is 1’ x 1’ • On your turn, you can do any combination of the following: move up to three space, rotate 90 and/or fire • A hit can be on any part of the battleship (no bounces!), 2 hits required to sink • Goal: Sink the enemy battleships before they sink you
Implementing Integrated Curriculum • Common Planning Time • Curriculum Mapping and Lesson Discussion
Implementing Integrated Curriculum • Curriculum Mapping and Lesson Discussion • Revising lessons: This lesson doesn’t fit my scope and/or standards • Removing lessons: We don’t have that subject teacher on our team • Adding lessons: My subject isn’t represented in the unit • Common Planning Time! • We don’t have time/structure to fit this into our school year • Single subject integration • Parallel/Paired integration
