Technology in a Bag
What is technology? What does your technology do? What
problem does it solve? How else could you use it? What materials are used to make it? What other material could be used to make
it?

What is technology?
Technology is: Anything human-made or used to solve a problem
or to fulfill a desire
Technology can be an object, system or a process. Can you identify a technology in this room that is a:
System Process

What can you do with a spoon?
What is an alternative function for this spoon?
If you were to think about redesigning this spoon so that it functioned better as a ______, what you change and why?
Who does this kind of work? Who uses their knowledge of science, materials properties and ergonomics to design technologies?

Science, Technology, Engineering
Engineering: Design under constraint Seeks solutions for
societal problems and needs
Aims to produce the best solution given resources and constraints
Engineering uses a process--the engineering design process--to produce solutions and technologies
http://www.mos.org/eie/
Science: A body of knowledge Seeks to describe
and understand the natural world and its physical properties
Scientific knowledge can be used to make predictions
Science uses a process--the scientific method--to generate knowledge
Technology: The body of
knowledge, processes, and artifacts that result from engineering
Almost everything made by humans to solve a need is a technology
Examples of technology include pencils, shoes, cell phones, and processes to treat water

Comparison of typical processes
Scientific Inquiry1.) Observation and form a question
2.) Hypothesis & procedure
3.) Conduct an experiment
4.) Refine hypothesis and experiment again
5.) Form a conclusion and communicate it
RESULT: Facts and theories
Engineering Design1.) Define the problem and resources available
2.) Develop a design
3.) Test the design
4.) Modify the design and test again
5.) Analyze the design and use or market it
RESULT: Products and processes

Engineering at work…
Ms. Campbell-Klett wants to put on display some of the Rainbow Lab Cylinders that her students have made in the 9th grade physical science in the large display cases near the Trojan head.
What is the problem? In order to solve this problem, what do you
need to know?

Tower Activity
Construct a tower to hold up a student rocket, the tower must be:
At least 2 feet tallStructure must support a stapler for 10 secondsCannot test the structure until the deadline is
reached (30 minutes) and cannot be anchored
Supplies your group may use: 1 pack of 100 index cards Scotch tape Scissors

Tower Activity
30 minutes

Tower Activity
What is similar about these solutions? What is different about them? After testing, what would you do if given the
chance to improve your tower?

Action Words
What are some action words that describe what you did during the design process?

Rocket lab redesign
Ms. Campbell-Klett wants to find a way to make the film canister rockets go higher. Brainstorm ideas in your lab groups for how this could look.
