1. T HE B UNGY E XPERIENCE Barbie and Friends go for a Bungy Jump – the analysis of the event

2. Real Life Imitated by Models

3. The Equipment From the front desk Collect 10 rubber bands A tape measure Loop 3 bands together, then attach them to Barbie’s ankles

4. Measuring the Fall Distance For 3 bands attached, measure the distance of the maximum fall Repeat the measurement 3 times Now do it again for 4, 5, 6, 7 rubber bands Record your results

5. Measuring the Fall Distance

7. Only 40 minutes to measure The time will disappear quickly

8. The Analysis You will need to Complete your average column Plot a graph for average distance & number of rubber bands Show the calculations for the linear model Calculate the averages (x,y) value for the Upper and Lower Section Calculate the gradient Calculate the y-axis intercept Write the equation of the line of best fit (2 mean method) Draw the line of best fit on the graph

9. Share the work load

10. The Analysis You will need to Complete your average column Plot a graph for average distance & number of rubber bands Show the calculations for the linear model Calculate the averages (x,y) value for the Upper and Lower Section Calculate the gradient Calculate the y-axis intercept Write the equation of the line of best fit (2 mean method) Draw the line of best fit on the graph

11. The Analysis 20 minutes to find your linear model y = mx + c

12. The Analysis You will need to Complete your average column Plot a graph for average distance & number of rubber bands Show the calculations for the linear model Calculate the averages (x,y) value for the Upper and Lower Section Calculate the gradient Calculate the y-axis intercept Write the equation of the line of best fit (2 mean method) Draw the line of best fit on the graph

13. From the LINEAR MODEL you shall predict the number of bands

14. THE JUMP – from where?

15. In 2004
