Activity: Physics behind bungee jumping
Part 1: Teacher Questions
(Review force and motion) Q1. What parameters should we consider to analyse a motion of bungee jumping? The teacher can encourage studnets to make a meaningful connection between motions caused by forces and energy by reviewing parameters that were used to define one-dimensional vertical motions such as gravity and tention as well as a time interval, a velocity, an acceleration, and a displacement in kinematics before staring to analyse the energy transformation in bungee junping activity. Teachers cannot assume that all the students are already comfortable with these basic concepts because they passed prerequisites. (Review energy) Q2. How can we relate the concepts we learned into a scenario of bungee jumping as they focus on energy transformation in the bungee jumping motion? Students will have a chance to explain in their own words how energy transformation is evident in the situation of bungee junping. The teacher can assess students' knowledge and understanding of the terminology and concepts. Part 2: Bungee jumping experiment The following framework can suggest students that they can analyse the motion as a series of predictions along the logical sequence over time. The resource on the right is a Grade 8 STEM project for Algebra lesson. The teacher can modify this activity to be suitable for Grade 12 Physics by changing the framework of the activity presented to the students as the following: Students will form groups to discuss the sequence of action and situation for a bungee jumper, Barbie, in this activity. The following is a guideline that the teacher can provide, so that students will have a clear idea of sequencing events and analysing energy and forces to predict the consequene of the actions in the second column as shown below.
