This is a PBL (Problem-Based Learning) activity for introductory physics relating to conservation of energy and gravitational potential energy. In this scenario, students are given a rough design for a bungee jump from a 20-meter tower and work cooperatively to determine the parameters for a safe jump. While some information is given, learners are required to research certain aspects, such as the medically-recommended maximum acceleration for an untrained jumper. PBL is an instructional method designed to strengthen student competency in reasoning and problem-solving. The activities mirror real scenarios encountered by practicing scientists and engineers. Learners sift through information to separate useful from irrelevant data, locate missing information on their own, and then apply physics in finding solutions. This resource includes a printable student manual and a password-protected teacher's guide with solutions and tips for instructors.

Integrate and evaluate multiple sources of information presented in diverse formats and media (e.g., quantitative data, video, multimedia) in order to address a question or solve a problem.

Synthesize information from a range of sources (e.g., texts, experiments, simulations) into a coherent understanding of a process, phenomenon, or concept, resolving conflicting information when possible.

Conduct short as well as more sustained research projects to answer a question (including a self-generated question) or solve a problem; narrow or broaden the inquiry when appropriate; synthesize multiple sources on the subject, demonstrating understanding of the subject under investigation.

Make sense of problems and persevere in solving them.

Reason quantitatively and use units to solve problems.

Choose a level of accuracy appropriate to limitations on measurement when reporting quantities.

Interpret the structure of expressions

Interpret expressions that represent a quantity in terms of its context ?

Interpret parts of an expression, such as terms, factors, and coefficients.

Use the structure of an expression to identify ways to rewrite it.

Build a function that models a relationship between two quantities

Write a function that describes a relationship between two quantities ?

Determine an explicit expression, a recursive process, or steps for calculation from a context.
