Ski Slope

• Building instructions book, pages 24 - 54

• Set the angle of the slope to 20 degrees and run each skier down the slope.
• Use a measuring tape to measure the distance travelled
• Record the distance on your Student Worksheet or on a similar chart in your science notebook.
• Make 3 runs with each skier, record the results on your worksheet and then calculate the average distance.

Now, set the angle of the slope to 30 degrees.

• Predict where you think each skier will finish and use 3 different coloured bricks to mark your predictions.
• Run each skier down the slope.
• Use a measuring tape to measure the distance travelled, and then record it.
• Make 3 runs with each skier, record the results on your worksheet and then calculate the average distance.
• Can you use the formula to calculate the mean (average) distance for each skier?

• Which forces did you observe?
• Was there a pattern?
• Which force made your skier stop?
• Were you able to use the formula to calculate the mean (average) distance for each skier?
