Building Bridges: Making the connection between Physics and Engineering. John Atherton Toronto District School Board
Who’s talking? Mechanical Engineering Degree Commissioning Engineer, Large Steam Turbines Design and build drinking water systems Corporate Underwriter, Boiler and Machinery Insurance Able to change a fuse/reset breakers
What’s the connection? Engineering is the application of science Thinking creatively: from concept to form Working in a team Communication; team, calculation, report writing, audience Design, Build, Test and start again!
Curriculum Links Lots! See file
Today 1. Calculating and designing in groups with whiteboards. 2. Labs - Comparing recipe/confirmation labs and investigating ‘real’ situations 3. Design and Build 4. Trips - taking it outside
Application based tasks
Today 1. Calculating for design - cooperative group problem solving –Car Crash Investigation –Riding the Wall of Death –Bungee Jump –The James Webb Telescope –Space Station - Mars 2. Labs 2 ways –pendulum and spring mass 3. Design, build and test –Trebuchet/Wind turbine/ Bridge building 4. Trips – Wonderland and Flying
Car Crash Investigation
Sam’s Ice cream shop – closed for the season Vehicles found fused together here in Sam’s empty car park Point of impact (from debris on road) Diagram of Accident Scene Width of both roads = 16 m Mass of car A = 1000 kg Distance = Angle = Mass of Truck B= 2200 kg V A =? V B =?
