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?

Scientific Inquiry
1.) Observation and form a question
Engineering Design
1.) Define the problem and resources
available
2.) Hypothesis & procedure
2.) Develop a design
3.) Conduct an experiment
3.) Test the design
4.) Refine hypothesis and experiment
again
4.) Modify the design and test again
5.) Form a conclusion and
communicate it
5.) Analyze the design and use or
market it
RESULT: Facts and theories
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 tall
Structure must support a stapler for 10 seconds
Cannot 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.

Engineering Design Process
Goal: To solve a problem by
developing or improving a
technology

Engineering Design Process
Ask
 What is the problem?
 What have others done?
 What are the constraints?
http://www.mos.org/eie/
Engineering Design Process
Imagine
 What are some solutions?
 Brainstorm ideas.
 Choose the best one.

Engineering Design Process
Plan
 Draw a diagram.
 Make lists of materials
you will need.
http://www.mos.org/eie/
Engineering Design Process
Create
 Follow your plan
and create it.
 Test it out!

Engineering Design Process
Improve
 Talk about what works, what
doesn't, and what could work
better.
 Modify your design to make it
better.
 Test it out!
