Overview: What is Engineering?
The nature of engineering makes up a large part of the Minnesota academic science standards. Engineering is a unique discipline, different from mathematics and science. This training day will allow teachers to connect their current ideas about engineering to expanded ideas about engineering and the engineering design cycle.
- IN THIS SESSION TEACHERS:
- Reflect on and expand their current ideas about engineering through a concept mapping activity.
- Explore the essential elements of the disciplines of engineering and how mathematics and science are related to engineering.
- Experience the engineering design cycle focused on wind turbines.
- Investigate the effects of blade design on electrical output.
Standards Specifically Addressed
- MINNESOTA ACADEMIC STANDARDS
- Grades 9-11: Distinguish between functions and other relations defined symbolically, graphically or in tabular form. (18.104.22.168)
- Grades 9-11: Represent and solve problems in various contexts using linear and quadratic functions. (22.214.171.124)
- Grades 9-11: Understand that quantities associated with physical measurements must be assigned units; apply such units correctly in expressions, equations and problem solutions that involve measurements; and convert between measurement systems (126.96.36.199)
- Grades 9-11: Understand and apply the fact that the effect of a scale factor k on length, area and volume is to multiply each by k, k2 and k3, respectively. (188.8.131.52)
- Grade 9: Engineering design is an analytical and creative process of devising a product or solution to meet a need or solve a specific problem:
- Identify a problem and the associated constraints on possible design solutions (184.108.40.206.1)
- Develop possible solutions to an engineering problem and evaluate them using conceptual, physical and mathematical models to determine the extent to which the solutions meet the design specifications (220.127.116.11.2))
- Select and use appropriate numeric, symbolic, pictorial, or graphical representation to communicate scientific ideas, procedures and experimental results (18.104.22.168.3)
- Grade 9: Identify the energy forms and explain the transfers of energy involved in the operation of common devices (22.214.171.124.1)
- Grade 9: Calculate and explain the energy, work and power involved in energy transfers in a mechanical system (126.96.36.199.2)
- Grade 9: Describe how an electric current produces a magnetic force, and how this interaction is used in motors and electromagnets to produce mechanical energy (188.8.131.52.5)
- Grade 9: Compare local and global environmental and economic advantages and disadvantages of generating electricity using various sources or energy. (184.108.40.206.1)
