  1. INLOT – SKI - JUMPING Lesson Plan Guided Research Model www.virtuelleschule.at/inlot

  2. General Information Duration: 8 x 50 min Vocabulary: velocity, acceleration, force, energy, inclined plane, aerodynamics Tools and Materials: notebooks, InLoT: hardware and software, internet

  3. General Informations Aims and Objectives:Students should deepen their basic knowledge in mechanics by studying one field of sports be able to use java applets independently in order to gain profound knowledge about forces be able to use InLoT hard- and software and analyse the obtained data learn how to organise an experiment outside the classroom

  4. Educational Phase 1 Stimulation: 1 x 50 min presentation of selected photos of ski jumpers, pole vaulters,… giving some impressions of a ski jump training camp (video clips) discussion about accelaration and forces acting on ski jumpers

  5. Educational Phase 2 Scientific Prediction: 1 x 25 min Students should find out about the following: what forces can be exerted on people ? do an internet research and give examples of different accelarations of people how does the acceleration of a ski jumper change during the different phases of the jump

  6. Educational Phase 3 Experimental Activities 11 x 25 min Run the java applets in order to understand how vectors combine to form the resultant on inclined planes

  7. Educational Phase 3 Experimental Activities21 x 50 min Plotting the graph of a vertical jump using the InLoT system

  8. Educational Phase 3 Experimental Activities3 1 x 50 min Plotting the graph of a ski jump from the K90 – jumping hill

  9. Educational Phase 4 Bouncing force: F = m·a ,m … mass of the jumpera … acceleration plotted in the diagram Impulse: Δp = F·Δt,Δt … time to jump off the ground (plotted in the diagram) Abstraction of the findings 1:vertical jump: 2 x 50 min

  10. Educational Phase 4 Height of jump t … half the time of the jumpg … acceleration of gravity Landing velocity v:potential energy equals kinetic energy:EPOT = EKINmgh = mv2/2

  11. Educational Phase 4 Breaking distance: a ...deceleration (plotted in the diagram)t … amount of time to decelerate (plotted in the diagram)

  12. Educational Phase 4 Abstraction of the findings 2:ski jump: 1 x 50 min

  13. Educational Phase 4

  14. Educational Phase 4 EPOT = EKINmgh = mv^2/2

  15. Educational Phase 5 Consolidation: 1 x 50 min discussion of evolving questions or problems analysis of a video which shows the vectors of acceleration at any time

  16. Educational Phase 5 Exercises: Hot Potatoes – Quiz about the mechanics of ski jumping Plotting the graph of one´s own vertical jump
