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.

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.

Pass out a copy of the Track Building Instructions to each group. 3) Go over the instructions and project requirements with the students. Be sure to show them the materials they have available for building their carts. 4) In their groups, students should identify the problems, criteria, priorities, constraints, and trade-offs associated designing and building carts. 5) Next, student groups should brainstorm initial hill solutions. They should build and test at least one design according to the instructions on their handout. Time permitting, there is also space on their handout to design more solutions. 6) Using their observations and data, students should write an essay recommending a proposed solution, which identifies both its strengths and weaknesses as well as describes how it is preferable to other solutions. As a conclusion to this essay, students should suggest further engineering that might be done to refine their recommendations.

For Teachers Engineering Design in Oregon Science Classrooms Page 8 of 13 APPENDIX 1A: 2009 STANDARDS MET WITH THIS LESSON General Science H.2P.3 Describe the interactions of energy and matter including the law of conservation of energy. H.2P.4 Apply the laws of motion and gravitation to describe the interaction of forces acting on an object and the resultant motion. Students will be able to describe the energy transformations that occur during a roller coaster ride. Students will examine how the law of gravitation affects the potential energy of a coaster cart. Students will examine how friction affects the kinetic energy of a coaster car. Engineering and Design H.4D.1 Define a problem and specify criteria for a solution within specific constraints or limits based on science principles. Generate several possible solutions to a problem and use the concept of trade-offs to compare them in terms of criteria and constraints. Students will identify problems in the design of a cart for a kiddie coaster ride and brainstorm solutions. Students will evaluate their design ideas using the concepts of trade-offs, criteria, and constraints. H.4D.2 Create and test or otherwise analyze at least one of the more promising solutions. Collect and process relevant data. Incorporate modifications based on data from testing or other analysis. Students will build prototype carts and collect data on their effectiveness. H.4D.3 Analyze data, identify uncertainties, and display data so that the implications for the solution being tested are clear. Students will present their data in an easy-to-read graph format, and write an analysis which clearly communicates both the uncertainties in the data as well as the implications for their prototype. H.4D.4 Recommend a proposed solution, identify its strengths and weaknesses, and describe how it is better than alternative designs. Identify further engineering that might be done to refine the recommendations. After building and evaluating their first solutions, students will write a paragraph detailing its strengths, a paragraph describing its weaknesses, and either a paragraph or a new sketch of recommended modifications. Scientific Inquiry H.3S.2 Design and conduct a controlled experiment, field study, or other investigation to make systematic observations about the natural world, including the collection of sufficient and appropriate data. Students will make observations about and collect data on the speed of their coaster carts in order to determine the effectiveness of their design. H.3S.3 Analyze data and identify uncertainties. Draw a valid conclusion, explain how it is supported by the evidence, and communicate the findings of a scientific investigation. Students will analyze data on sample hill and coaster cart prototypes to help them identify design problems, generate solutions, and build new prototypes. Students will analyze data in order to evaluate and write an analysis of their hill and coaster cart designs, which clearly communicates both the uncertainties in the data as well as the implications for their prototypes.

(HS-ETS1-1) For Teachers Engineering Design in Oregon Science Classrooms Page 10 of 13 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.
