Mag. Ronald Binder Mag. Veronika Ruedegger INLOT – SKI - JUMPING Lesson Plan Guided Research Model www.virtuelleschule.at/inlot

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

Mag. Ronald Binder Mag. Veronika Ruedegger 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

Mag. Ronald Binder Mag. Veronika Ruedegger 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

Mag. Ronald Binder Mag. Veronika Ruedegger 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

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 3 Experimental Activities 1 1 x 25 min Run the java applets in order to understand how vectors combine to form the resultant on inclined planes

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 3 Experimental Activities 2 1 x 50 min Plotting the graph of a vertical jump using the InLoT system

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 3 Experimental Activities 3 1 x 50 min Plotting the graph of a ski jump from the K90 – jumping hill

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

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 4 Height of jump t … half the time of the jump g … acceleration of gravity Landing velocity v: potential energy equals kinetic energy: E POT = E KIN mgh = mv 2 /2

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 4 Breaking distance: a...deceleration (plotted in the diagram) t … amount of time to decelerate (plotted in the diagram)

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 4 Abstraction of the findings 2: ski jump: 1 x 50 min

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 4

Mag. Ronald Binder Mag. Veronika Ruedegger Educational Phase 4 E POT = E KIN mgh = mv^2/2

Mag. Ronald Binder Mag. Veronika Ruedegger 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

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