● Review of Marshmallow Mania DC

● Design

● Exit Pass

Science Study of the natural world

Technology Study of the manmade

world

Engineering Math Study of numbers and quantity

What is engineering and why is it important in science class?

Engineering is solving problems by using both math and science.

Engineering Vocabulary

1. Criteria: “Must Haves”

2. Constraints: Limitations

3. Prototype: First model

Engineering Design Process: a series of steps that engineers follow to come up with a solution to a problem.

Redesign

Test

Build

Design

Understand the Problem

Research & Brainstorm

Communicate

DESIGN PROCESS

UNDERSTANDING THE PROBLEM/ DESIGN BRIEF

What is the problem?

What are the criteria and constraints?

How can you solve it?

DESING BRIEF: A written plan that identifies a problem to be solved, its criteria, and its constraints.

The design brief is used to encourage thinking in all aspects of a problem before attempting a solution

Research & Brainstorm

BRAINSTORM: A method of shared problem solving in which all members of a group spontaneously and in an unrestrained discussion generate ideas.

Find out what others have done.

Think up lots of ideas.

Observe the materials.

Examine current state of the issue andcurrent solutions

RESEARCH: Identifying what information you know and what you need to know about your problem to create your solutions.

Design

An iterative decision-making process that produces plans by which resources are converted into products or systems that human needs and wants or solve problems.

Draw sketches and make a final decision

Sketches include measurements (including units) and labels.

Brainstorm possible solutions Draw on mathematics and science

Articulate the possible solutions in two and three dimensions

BuildUse your plan to build your ideas. Determine which solution(s) best meet the original requirements

TestDoes my model work?Does it solve the problem? Test your idea.

Redesign

Think about how your design can be improved.

Modify your design and try again.

An iterative decision-making process that produces plans by which resources are converted into products or systems that human needs and wants or solve problems. *

Overhaul the solution(s) based on information gathered during the tests and presentation

COMMUNITCATE / EVALUATE

Communicate your results with others.

Discuss societal impact and tradeoffs of the solutions

Make an engineering presentation thatincludes a discussion of how the best meet(s) the needs of the initial problem, opportunity, or need.

•Guidelines, rules, or tests by which something can be judged. Criteria are specific and measurable.•Must Haves

Criteria

• A limit to a design process. Constraints may be such things as appearance, funding, space, materials and human capabilities

• Limitations

Constraints•A full-scale working model used to test a design concept by making actual observations and necessary adjustments.•First model

Prototype
