- 2. Scientists Investigate our natural world Technologists Apply science and math to designs Mathematicians Use numbers and symbols to solve problems Engineers Create our designed world STEM Working together to solve problems based on societal needs and wants
- 3. Science vs. Technology • Scientists investigate our natural world • Engineers help create the human- designed world • Technology (or technologies) denotes the products and processes created by an engineer and often used by a scientist (the “stuff” or “things” we use)
- 4. How are each of them needed to Create a Product? Example Science Technology Engineering Math Pencil Resources Idea Design, using your idea with the resources you have Size and shape Dimensions
- 5. How are each of them needed to Create a Product? Example Science Technology Engineering Math Pencil Discovery of graphite and the fact that rubber (an eraser) will remove graphite Creating a writing device that doesn’t use ink Designing a device with a graphite insert, an exterior holder, and an attached eraser What is the optimal length, diameter, or shape for the device?
- 6. Science…Math… • Knowledge of science and math is necessary for the creation of new technologies • People working in multiple career areas helped put the cereal you may have eaten this morning • Think about the tables and or chairs you may have used so far today.
- 7. Scientists…Engineers… • Information from a scientist helped the farmer to plant, grow, and harvest the grains (corn, oats, wheat, rice, and barley) • The responsibility of an engineer includes designing the equipment used to harvest the grain and designing the factory where the grain was processed into what you eat today
- 8. Engineers…Technologists… • An engineering technologist built the factory, built the tools and equipment necessary for converting the grains into cereal • Engineering technologists were part of a team that built the farm equipment (that an engineer designed)
- 9. Mathematicians… • All along the way, mathematicians were needed to solve problems…like how big the factory should be or how much cereal should go in one box • Have you ever noticed that most cereal boxes are the same width, but they vary in height and/or thickness? Why do you think these particular dimensions are chosen?

- 16. What is Engineering? Key Terms • Engineering Using technological and scientific knowledge to solve practical problems • Environment The surroundings in which a person, animal, or plant lives • Ergonomics The study of workplace equipment design or how to arrange and design devices, machines, or workspace so that people and things interact safely and most efficiently
- 17. What is Engineering? Key Terms • Industrial Anything relating to (or resulting from) industry, manufacturing, production, etc. • Invention A new product, system, or process that has never existed before, created by study and experimentation • Innovation An improvement of an existing technological product, system, or method of doing something
- 18. What is Engineering? Key Terms • Manufacturing The process of making a raw material into a finished product; especially in large quantities • Math The science of patterns and order and the study of measurement, properties, and the relationships of quantities using numbers and symbols
- 19. What is Engineering? Key Terms • Nanotechnology The science and technology of building devices, such as electronic circuits, from single atoms and molecules • Process Human activities used to create, invent, design, transform, produce, control, maintain, and use products or systems; a sequence of actions that combines resources to produce an output
- 20. What is Engineering? Key Terms • Science The study of our natural world through observation, identification, description, experimental investigation, and theoretical explanations • System A group of interacting, interrelated, or interdependent elements/parts that function together as a whole to accomplish a goal
- 21. What is Engineering? Key Terms • Technology The way people use resources to meet their wants and needs; the devices humans use • Transportation The process by which passengers or goods are moved or delivered from one place to another
- 22. What is Engineering? Essential Questions 1) What is the purpose of a portfolio for a student? 2) What is the purpose of a portfolio for an engineer? 3) Why is it important for engineers to document their work in their engineering notebook?
- 23. What is Engineering? Essential Questions 4) List some ways our lives are affected by engineers? 5) What is the difference between an invention and an innovation? 6) How does the use of technology affect the way that you live?
