Ramp Race Day 1

Today we are starting our culminating task inspired by Al Overwijk (blog)

We have a 3 degree ramp at our school that is 8 meters long. We are going to race 5 different balls down the ramp. To predict which one will win, we are modelling the ramp in our classroom with 6 different lengths of board.

We had to calculate how high up the rise should be. We had to figure out how to elevate the board, and keep it stable.

Once the ramp was made, we chose 4 locations along the board to start rolling the ball. Each ball will be rolled 3 times from each location and averaged.

We’re busy filling data into our table of values.

We’ll keep working tomorrow, to get through testing all 5 balls at each location, then we’ll do some analysis to figure out how to model the relationships.
