Aim: What Is Engineering?

2. Objectives for Today (9/9)
Discuss classroom rules and expectations and review procedures for homework
Based on last night’s reading:
Define: engineering, constraints, specifications
Identify and discuss specific examples of engineering in the current issue of Science World
Compare/contrast: scientific method vs. engineering design process

3. 1. Class Rules and Expectations
Come PREPARED to class every day. ALWAYS have with you:
pens, pencils, and lined paper for taking notes
a calculator
a pocket folder for holding class handouts, articles, homework sheets, tests etc.
Homework
must be handed in or presented at the beginning of class
daily homework (3-5 questions from a HW sheet, reading and summarizing a science article, completing a review sheet) receives either a ✓ for completion or an X if incomplete
Larger assignments (lab reports, completed HW sheets, research projects) that are handed in late will receive point deductions.

4. C. Speaking in Class
Only one student may speak at a time, after he/she is called on by Mr. T-W.
Calling out and interrupting others will NOT BE TOLERATED and can negatively affect your conduct grade.
D. Only ONE STUDENT may leave the classroom at a time to use the bathroom or get a drink of water.
E. No eating in the classroom. The only acceptable form of food or drink permitted in the classroom is a clear bottle of water

5. 2: Defining Terms:
➡ Directions: Split up into groups of 3, and spend 3-4 minutes creating definitions for the 3 terms below. Be prepared to share your definitions with the class.
engineering: using STEM to create products and systems that improve the world
constraints: limitations of your design (cost, time, materials)
specifications: requirements of your design

6. 3: Engineering in Science World
➡ Directions: In your same groups, spend another 3-4 minutes identifying specific examples of engineering in the current issue of Science World. Be prepared to share 1-2 examples.
List of examples: -

7. Engineering Fundamentals Definitions:
Uses math, science, and technology
Creates products and systems
Improves world
Specifications:
