Review- 7th

Rules

• 1 right answer= 1 candy• If you do not like the candy, hold onto it until

the end of the class to replace it• If you did not have the correct answer or did

not do the assignment, jot down the correct answers for the test tomorrow

• If we do not get all the way through, this PowerPoint is on my website

What is Technology?

Technology is comprised of the products and processes created by engineers to meet our needs and wants.

• What are different kinds of technology (products)?

What is an engineer/ engineering?

Engineer- A person who is trained to solve practical problems through applying their knowledge of technology, science, and math.

E.C.- What are the four big types of engineering?Big four- Mechanical, Civil, Chemical, and Electrical

Technology is comprised of the products and processes created by engineers to meet our needs and wants.

• What are needs? Needs- something that is essential

to life.What are wants?

Want- something that is desired.

• What are some examples of each?

Vs.

What are inventions?

• Invent – Develop a new product, system, or process that has never existed before

What are innovations?• Innovate – Improve an existing technological

product, system, or method

What is the process used by engineers to solve problems?

The design process

What is the definition of the design process?

• the step by step method to solving problems.

What is this?

What is a constraint?

A constraint is a limitation or restriction placed on your project.

• Unlike criteria, a constraint is very defined. It either “is” or it “is not”.

• You must stay within a constraint. Going outside of a constraint can cause problems

• Usual constraints: cost, time, materials, minimum/ maximum, laws, features etc.

What is Brainstorming?Brainstorming- a group technique used to generate as many

ideas for a possible solution.

Why? -Fact: Your first idea is 99% of the time not the best.- Generating a overwhelming amount of ideas will make the decision process easier, as you can go back and review it.- Even if you know its bad write it down

What Is a Design Process?

A design process is a step-by-step problem-solving strategy used to find the best possible solution.

• In a nut shell, it helps us take our ideas, allows us to choose the best one, and make them reality

What are the steps of the design process?

1. Define the Problem2. Generate Concepts3. Develop a Solution4. Construct and Test a

Prototype5. Evaluate the Solution6. Present the Solution

This design process was developed based on the University of Maryland - College Park - IRB Research Project

What is the purpose of sketching?

• Sketching is a universal language that communicates ideas visually

What is this type of drawing called?

• 2D illustration of a 3D object• Shows three faces of an object in one view• Provides a realistic view of an object

What is an isometric drawing?

What is this type of drawing called?

What is a Multiview Drawing?• Represents a 3-D object in two or more views drawn in

2-D

• Provides the shape description of an object.

What is an object line?

• Communicates the actual shape of an object

• Thick and dark• Define the object

What is a hidden line?

• Communicates the hidden part of the object that you can not see in that view

• Even, dotted lines

Where is the front view?

Where is the top view?

Where is the right side view?

Which one is centimeters? Which one is inches?

– Standard (Customary)

- Metric (SI or International System)
