Course Description:

Engineering I: This course is designed to introduce students to the world of Engineering Design and problem solving through the design process. The course I designed for any student who intends to pursue future training in any engineering program or technical industry. Students use problem-solving models to improve existing products while utilizing development processes to create new products. They will learn how to apply these models to solve problems in and out of the classroom setting. Students will apply mathematical and scientific concepts and models when being introduced to the fundamentals of mechanical; structural (civil; architectural and green technology); aeronautical; and robotic (VEX IQ) engineering and electrical concepts. Students will use multiple software packages; engineering poster sessions; and presentations to develop technical communication literacy skills. Computer assisted instruction; lab activities and classroom discussions will be used to create a foundation for problem solving and engineering concepts. Career and Technical Student Organization (CTSO) standards will be an integral part of this class. Dual credit may be obtained from Embry Riddle Aeronautical University for this program at high schools offering this option. An honors option is available to all students enrolled in the course. Students mathematically model the kinematics of projectile motion from a small catapult. Students perform a mathematical analysis CO2 car travel based on potential and kinetic energy on a ramp; determine the velocity at the bottom of the ramp; determine the acceleration of car and determine the force of friction between the car and the floor; students determine the force the CO2 cartridge imparts on the car and the rate of acceleration after the cartridge is spent. Students determined the mathematical relationships between the volume of a hot air balloon; pressures and ambient temperature. Students spend approximately 6 hours per week in lab.

Engineering II: This course builds on skills learned in Engineering I; while introducing students to electrical engineering; control systems; the application of green technologies; three dimensional modeling; computer aided manufacturing (CNC) and advanced robotics concepts (VEX). This class incorporates various technological processes and manufacturing technologies. Students will develop a sense of the interdependency of the various engineering disciplines. Students will also develop an understanding that engineering is a human endeavor intended to address the needs of a global society. Utilizing activities; projects and problems; students will develop the skills to solve problems using math; science; and technology in engineering processes to benefit society. The use of CAD/CAM industry based software and equipment will be an extensive part of this class. Students will be introduced to state of the art robotic software. Students will apply concepts of mechanical; electrical and control systems in various design problems. This course will continue to develop technical communication literacy (reading; writing; and speaking). Career and Technical Student Organization (CTSO) standards will be an integral part of this class. Dual credit may be obtained from Embry Riddle Aeronautical University for this program at high schools offering this option. An honors option is available to all students enrolled in the course. Students utilize three dimensional geometric relationships as they develop their skills in Computer Numeric Control. Sample problems presented in this class include:

I. When an oil company drills a new oil well they are only capable of extracting approximately 35% of the oil available. Your job is to develop a way that is economically viable and environmentally responsible; to extract at least 50% more of the oil. Requires the use of volumes; mathematical functions; statistics; and defending a mathematical argument. Students need to consider flow rates; viscosity; temperature; pump pressures; and pipe diameters.

II. The Ogallala Aquifer occupies the High Plains of the United States; extending from western Texas to South Dakota. The Ogallala Aquifer is used to water the crops and cattle that we use for food. We will no longer be able to get water from the Ogallala Aquifer sometime in next 50 years. Your job is to develop a way to continue to water the crops and cattle of the American Midwest without using the aquifer. Your solution must be economically viable and environmentally responsible. Students need to consider the possibility of geometric regression for water usage (from the aquifer); geometric growth for water usage; flow rates; volume; mathematical functions; statistics and be able to defend a mathematical argument.

III. The current EPA regulations are making it increasingly difficult to use the most abundant energy source in the United States. With the current technology; alternative energy is unreliable. This leaves nuclear energy as the best option at this time. When nuclear fuel rods are removed as ‚Äúused‚Äù from the reactor; 99% of the uranium has not been used. Your job has two parts. First; you must develop a way to recycle the fuel rods so that they may be reinserted into the reactor. Second; develop a way to utilize the radiation energy being emitted from the waste material. Your solution must be economically viable and environmentally responsible. Note: The issue with storage of nuclear waste in the United States is a political issue; not one of science or technology. Students need to use exponential functions; geometric series; geometry; combinational number theory; functions and be able to defend a mathematical argument.

IV. The average family in the United States deposits 4.3 pounds of solid waste into landfills every day. This creates a large impact on open spaces and land resources. Your job is to develop a way (other than recycling) to reduce the impact of the amount of waste that is placed in these landfills. Your solution must be economically viable and environmentally responsible. Students need to consider exponential growth; geometry; and statistics and be able to defend a mathematical argument.

V. The current scientific theories claim that global climate change is the result of human activity in the form of releasing carbon dioxide into the atmosphere. It is necessary to continue using the energy that creates the carbon dioxide in order to maintain the global economy. Your job is to develop an economically viable and environmentally responsible way to sequester the carbon dioxide that is being emitted into the atmosphere. Students need to consider geometric series; geometry; statistics and algebraic functions as well as being able to defend a mathematical argument.

VI. One sixth of the world‚Äôs population does not have access to potable drinking water. Your job is to develop a way to provide a sustainable method to provide safe; clean drinking water to these populations. You may assume that a water source is available. Your solution must be economically viable and environmental responsible. Students need to consider population growth; statistics; flow rates; algebraic functions and be able to defend a mathematical series.

VII. In 2005; Hurricane Katrina devastated the city of New Orleans. Despite many overtones; not much has been done to prevent a repeat of the event. Your job is to develop an economically viable and environmentally responsible way to safeguard the people and the property of New Orleans against a repeat of a Katrina-like disaster. Students need to use geometry; statistics; probability; and algebraic functions as well as be able to defend a mathematical argument.

VIII. Approximately 12.5% of the global population suffers from chronic malnourishment. While there are many reasons for this; the primary reason is access to food. Your job is to develop a way to provide healthy food to these people. Your solution should be economically viable; environmentally responsible and sustainable. Students need to consider population growth; geometry; and statistics and be able to defend a mathematical function.

Students spend approximately 6 hours per week working on projects/labs.

Engineering III: This course applies engineering technology and skills to the manufacturing processes while recognizing that engineering is a human endeavor intended to address the needs of a global society. This course will examine the relationship of manufacturing and process development to the world of engineering. Students will use advanced engineering design; production; and programming techniques for Mobile robotics (VEX); Robotic Arm; 3 Dimensional Modeling; and Computer Numerical Control (CNC). Students will incorporate mathematical and scientific modeling and processes in order to solve real world manufacturing and production problems. Students will identify the impact of various engineering disciplines on manufacturing processes. Students will continue to utilize and improve technical communication skills (reading; writing; and speaking). Students will investigate the impact of manufacturing and robotics on both local and global societies. Career and Technical Student Organization (CTSO) standards will be an integral part of this class. Dual credit may be obtained from Embry Riddle Aeronautical University for this program at high schools offering this option. An honors option is available to all students enrolled in the course.
