1—LESSON OVERVIEW
1.1—Introduction
In this engineering lesson, students will address the problems associated with creating a roller coaster
ride for kids. Their ultimate goal is to design carts that hold as many passengers as possible for a new
amusement park ride on Mount Jefferson. The lesson is divided into three parts.
 Part 1 is a reading activity to familiarize students with the physics behind roller coasters.
 Part 2 is an exploration activity which allows students to examine the relationship between gravitational
potential energy, kinetic energy, and track design.
 Part 3 is an engineering activity where students will design, build, test, and evaluate cart designs for a
pre-set track. Optional: design, build, test and evaluate track designs.
1.2—Lesson Breakdown with Engineering Design
Engineering Design Steps
1. Define a problem that
addresses a need
2. Identify criteria,
constraints, and priorities
3. Describe relevant scientific
principles and knowledge.
4. Investigate possible
solutions and use the concept
of trade-offs to compare
solutions in terms of criteria
and constraints.
5. Design and construct at
least one proposed solution.
6. Test a proposed
solution(s), collect and
process relevant data and
incorporate modifications
based on data from testing or
other analysis.
7. Analyze data, identify
uncertainties, and display
data so that the implications
for the solution being tested
are clear
8. Recommend a proposed
solution, identify its strengths
and weaknesses, and describe
how it is better than
alternative designs as well as
identifying further
engineering that might be
done to refine the
recommendation.

1.3—Pre-Requisite Knowledge
Students should be familiar with the engineering design concepts of criteria, priorities, constraints, and
trade-offs.
2—TEACHER BACKGROUND INFORMATION
2.1—Glossary of Terms
Acceleration: A change in an object’s velocity. Acceleration equals a change in velocity divided by
time.
Friction: A force which opposes motion.
G-Force: Acceleration felt as weight. It is not a straight-up force like friction, but rather a force per unit
mass. 1 g-force equals acceleration due to gravity or 9.8 m/s².
Gravitational Potential Energy: Stored energy due to height. GPE = Mass x Gravity x Height.
Kinetic Energy: Energy of motion.
Inertia: The tendency of an object to resist changes in motion, equal to its mass
Law of Conservation of Energy: Energy cannot be created or destroyed, it can only change forms.
Velocity: A rate of motion. Velocity equals distance divided by time and because it is a vector quantity
both magnitude and direction are needed to define it.
2.2—Scientific Concepts and Disciplinary Core Ideas
See the Article Handout for the scientific concepts covered in this lesson.

Constructing Explanations and Designing Solutions
 Constructing explanations and designing solutions in 9–12 builds on K–8 experiences and progresses to
explanations and designs that are supported by multiple and independent student-generated sources of
evidence consistent with scientific ideas, principles and theories.

Design a solution to a complex real-world problem, based on scientific knowledge, student-generated
sources of evidence, prioritized criteria, and tradeoff considerations. (HS-ETS1-2)

Evaluate a solution to a complex real-world problem, based on scientific knowledge, student-generated
sources of evidence, prioritized criteria, and tradeoff considerations. (HS-ETS1-3)
Disciplinary Core Ideas
ETS1.A: Defining and Delimiting Engineering Problems

Criteria and constraints also include satisfying any requirements set by society, such as taking issues of risk
mitigation into account, and they should be quantified to the extent possible and stated in such a way that one can
tell if a given design meets them. (HS-ETS1-1)

Humanity faces major global challenges today, such as the need for supplies of clean water and food or for
energy sources that minimize pollution, which can be addressed through engineering. These global challenges
also may have manifestations in local communities. (HS-ETS1-1)
ETS1.B: Developing Possible Solutions

When evaluating solutions, it is important to take into account a range of constraints, including cost, safety,
reliability, and aesthetics, and to consider social, cultural, and environmental impacts. (HS-ETS1-3)

Both physical models and computers can be used in various ways to aid in the engineering design process.
Computers are useful for a variety of purposes, such as running simulations to test different ways of solving a
problem or to see which one is most efficient or economical; and in making a persuasive presentation to a client
about how a given design will meet his or her needs. (HS-ETS1-4)
ETS1.B. Designing Solutions to Engineering Problems

When evaluating solutions, it is important to take into account a range of constraints, including cost, safety,
reliability, and aesthetics, and to consider social, cultural, and environmental impacts.
ETS1.C: Optimizing the Design Solution

Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions
about the priority of certain criteria over others (trade-offs) may be needed. (HS-ETS1-2)
