Lift Data

Published on 01/11/2014

Activity Overview

Students will use authentic data to graph and analyse the altitude of two different lifts over a period of time in order to determine travel time, speed and the number of floors visited.

Objectives

  • ACMNA208 – Solve problems involving direct proportion. Explore the relationship between graphs and equations corresponding to simple rate problems
  • Students learn to use a line of best fit to estimate the gradient and speed of a lift. They also learn to use the gradient formula to determine the slope of a line between two points.

Vocabulary

  • Acceleration
  • Velocity
  • Speed
  • Distance
  • Slope
  • Gradient

About the Lesson

Students calculate and compare the speed of two lifts as they travel between floors of their respective buildings. Students calculate the speeds of the lifts by graphing the data and drawing the lines of best fit. They then compare their calculations by selecting two points and using these to calculate the gradients of the lines.
