This method encourages students to learn skills and apply their knowledge by taking part in a project. They work for an extended period to research and create a solution to a problem or query. Your role as a teacher is to be a facilitator and encourage students to take full control of their projects from start to finish.
– Using the Engineering Design Process (EDP)
This is a series of steps students can take to design solutions to problems as part of a project. This project-based learning strategy should encourage open-ended designs, creativity and practical solutions.The steps of EDP:
ASK: Students identify the problem, requirements that must be met, and constraints that must be considered.
IMAGINE: Students brainstorm solutions and research ideas. They also identify what others have done.
PLAN: Students choose two to three of the best ideas from their brainstormed list and sketch possible designs, ultimately choosing a single design to prototype.
CREATE: Students build a working model, or prototype, that aligns with design requirements and that is within design constraints.
TEST: Students evaluate the solution through testing; they collect and analyze data; they summarize strengths and weaknesses of their design that were revealed during testing.
IMPROVE: Based on the results of their tests, students make improvements on their design. They also identify changes they will make and justify their revisions.
Potential &Kinetic Energy, Law of Conservation of Energy, Gravity
In this lesson, students will learn to think and design like an engineer by utilizing the engineering process to design a roller coaster using pipe insulation, marbles, and objects within the room.. Computer simulation programs will aid in finding different ways roller coasters can be designed, taking into account variables like height, velocity, gravity, and the roller coaster path. The students will be divided into groups where they will learn to interact and work in a team setting because Engineers need to be great communicators! First, they will go through a presentation highlighting how roller coasters are designed, and the physics behind why they work. They will plan out their design using the fundamental principles they learned in the presentation. Lastly, the students will create a roller coaster using flex pipe insulation as the structure, tape, and a marble representing the cart full of passengers. They can be as creative as they want, using materials found around the room to help with their structure and path. Students will design, evaluate, and improve throughout the lesson, experiencing the process engineers go through on a daily basis!
You are president of an engineering firm that designs and builds roller coasters. Vialand has just commissioned you and your team of highly trained and specialized engineers to design their new roller coaster. This is to be the premier roller coaster in the world. It is to be faster and more thrilling than any other coaster that exists today.
Your new roller coaster must have at least on hill, one loop, one corkscrew, and one turn. Your group must first create a design for your roller coaster and a name for it. You need to create a new sign with your roller coasters name on it as well. Once your design and name have been approved, you will create this roller coaster with the supplies given. Once the roller coaster is completed, you will do time trials with different marbles to see how fast the marble is traveling. Each group will be graded on the creativity of your project and if you met all of the criteria. At the end of this project, the class will vote on which roller coaster had the best overall design.
Design a safe and fun roller coaster using available materials!
CRITERIA & CONSTRAINTS:
1-Build a roller coaster that has 2 hills OR 1 loop and 1 hill.
2- A marble will be used as the vehicle for your marble roller coaster.
3- The marble must travel the entire length of the roller coaster to be considered
1.Construct a rollercoaster that has at least 2 high points (the start can be one) where you can observe potential energy converting to kinetic energy.
a.Identify these areas with a toothpick
2.You may use any of the provided materials to construct your rollercoaster
3.Record your Hypothesis as an “If— Then—-” statement based on which area will have the greatest potential energy (Annex 4.)
4.You must name your ride!
5.Run the marble through the rollercoaster 10 times to determine an average velocity in m/s. You will record in the data Roller Coaster Design Handout (Annex 3.)
6.Determine the potential energy using the equation you provided in the warm up.
After you have successfully completed the basic project and your teacher has approved your design, you may modify it for extra credit points: additional hills, loops, and/or your marble stopping within 15 cm off the end. See rubric for scoring!
Mechanical engineers: design the roller coaster, how the cart is going to hold on to the track, how it moves throughout the ride, how the breaks and mechanics work, etc
Electrical engineers: work on the moving electrical components, work with the computer engineer to make sure the circuit boards, and control panel all work.
Computer engineers: work on the computer system that controls the roller coaster
Structural engineers: make sure it is structurally sound, they build all of the white structures you can see on the picture, make sure it will stay standing!
Chemical engineers: gas propulsion for some roller coasters
Aerospace engineers: make the carts aerodynamic so they don’t have as much friction and can go as fast as possible
Material engineers: decide what materials to use for each part that will work the best and be the cheapest, withstand the weather in different areas of the world
Transportation Engineers: It’s similar to designing a very curvy, complicated road!
Engineering is all about working together! All of these different kinds of people work to make something fun for people to enjoy. It is all about finding solutions to problems helping people and improving their lives.
Eight 40 minutes lessons
Students build their own small-scale model roller coasters using pipe insulation and marbles, and then analyze them using physics principles learned in the associated lesson. They examine conversions between kinetic and potential energy and frictional effects to design roller coasters that are completely driven by gravity.
During the design of model roller coasters, students encounter many of the same issues that real-world roller coaster engineers address. In order to build working roller coasters, students must recognize the constraints placed on their designs and the design of real roller coasters by the fundamental laws of physics. Students learn that their ability to understand and work within these constraints is paramount to the success of their roller coasters.
After this project, students should be able to:
Civil engineers design structures like roller coasters, bridges, and buildings.
Energy: The ability to cause changes in matter
Potential Energy: The energy an object has because of its position or its condition
Kinetic Energy: The energy an object has because of motion
Motion: The change in position of an object
Force: A push or a pull, which may cause a change in an object’s motion
Gravity: The force of attraction between two objects
Friction: A force that acts between two touching objects and that opposes motion
Acceleration: A vehicle’s capacity to gain speed
Balanced and unbalanced forces:
A balanced force results whenever two or more forces act upon an object in such a way as to exactly counteract each other. As you sit in your seat at this moment, the seat pushes upward with a force equal in strength and opposite in direction to the force of gravity. These two forces are said to balance each other, causing you to remain at rest. If the seat is suddenly pulled out from under you, then you experience an unbalanced force. There is no longer an upward seat force to balance the downward pull of gravity, so you accelerate to the ground.
Centripetal force: A centripetal force is a net force that acts on an object to keep it moving along a circular path.
g: A g is a unit of acceleration equal to the acceleration caused by gravity. Gravity causes free-falling objects on the Earth to change their speeds at rates of about 10 m/s each second
İnertia: Inertia is a tendency of an object to resist change in its state of motion.
Mass: The mass of an object is a measurement of the amount of material in a substance.
Momentum: Momentum pertains to the quantity of motion that an object possesses. Any mass that is in motion has momentum.
Newton’s First Law of Motion: An object at rest or in uniform motion in a straight line will remain at rest or in the same uniform motion unless acted upon by an unbalanced force. This is also known as the law of inertia.
Newton’s Second Law of Motion: The acceleration of an object is directly proportional to the total unbalanced force exerted on the object, and is inversely proportional to the mass of the object (in other words, as mass increases, the acceleration has to decrease). The acceleration of an object moves in the same direction as the total force. This is also known as the law of acceleration.
Newton’s Third Law of Motion: If one object exerts a force on a second object, the second object exerts a force equal in magnitude and opposite in direction on the object body. This is also known as the law of interaction.
Period: A motion that repeats itself in cyclic fashion is said to be periodic. The time for one complete cycle is known as the period of the motion. The motion of a second hand has a period of 60 seconds. The periodic rotation of the earth about its axis is 24 hours.
Speed: Speed is a measurement of how fast an object is moving.
Roller coasters at amusement parks utilize potential energy and kinetic energy. Typically, a motor pulls up the roller coaster car to gain its initial potential energy. Once at the peak point, no motors are connected to the car in any way. The car begins its winding and looping decent along a track that has been designed to safely convert potential energy into kinetic energy while making it a thrilling ride.
If the car goes through a loop-de-loop and does not have enough kinetic energy, it will not stay on the track as it reaches the peak of the loop. Kinetic energy is measured as KE=(mv2)/2, where m is the mass of the object and v is the velocity. Potential energy is measured as PE=mgh, where m is the mass, g is the gravitational force, and h is the distance above the reference point where the mass starts.
Ideally, all the potential energy is converted to kinetic energy, but in reality, this never holds true, since some of the energy is lost to friction. Because of the loss of energy, the peak of the loops must be lower than the initial starting point of the car.

The RollerCoaster project is where students come together as a team to build a complete roller coaster. This project based activity is aimed to motivate and energize students. They learn about project management and the importance of collaborating effectively as a team. This understanding gets applied to the work scenario as well. Roller Coaster is an exciting activity where students have to build an entire roller coaster with the materials provided to them. It should be designed in such a way that the marble is able to run along the track solely with the help of gravity.

|1. How do potential and kinetic energy effect a roller coaster?
|2. What is role of gravity in the movement of the roller coaster?
|3. What is the impact of momentum on the roller coaster movement?
|4. How does the law of Conservation of Energy apply to how a roller coaster moves?
|5. Explain how the three laws of motion are essential to the movement of a roller coaster:
|6. When watching the movement of a roller coaster, when do you observe Newton’s First Law of Motion?
|7. When watching the movement of a roller coaster, when do you observe Newton’s Second Law of Motion?
|8. When watching the movement of a roller coaster, when do you observe Newton’s Third Law of Motion?
|9. Explain the relationship between speed and velocity in regards to the movement of a roller coaster.
|10. How is force, a push or a pull on matter, demonstrated in the movement of a roller coaster?
|11. List and explain all observable forms of energy when watching the movement of a roller coaster.
Figure 1. In this figure: the coaster starts out at the top of the first hill with maximum potential energy (PE) and almost no kinetic energy (KE) (1). As it goes down the hill, it gains KE and loses PE (2). At the bottom of the hill, it has maximum KE but almost no PE (3). As it goes back up the hill, it loses KE but gains PE again (4). It can never get to the top of the second hill because it does not have enough energy (5). Instead, it will roll back down and eventually settle at the bottom (3)
Figure 2. In this figure, the second, third, and so on hills are all shorter than the first hill (1). However, because of friction, the roller coaster will still eventually come to a stop (4)
