Intro to Tech

Technology is
The application of knowledge, creativity,
resources to solve real world problems and
extend human capabilities.
Involves taking natural materials turning
them into useful products
Involves using knowledge of scientific
principles to change resources into products
needed by a society.

Technology moves forward by adapting

machines and tools

Problem Solving Method

• Identify the problem
• Must get the ropes apart without taking the rope
  off either students wrist
• Build a carrier that will protect the egg from
  breaking

• Define and represent the problem
• Eight groups need to have the same measuring tool
• All groups need to use the same measurement scale

6
Problem Solving Method

• Explore possible strategies
• Drawing thumbnail sketches
• Brainstorming ideas for project

• Act on the strategies
• Clean the radiation residue around Chernobyl
• Make the egg drop carrier

7
Problem Solving Method

• Look back and evaluate the effects of our
  activities
• The carrier was weak because it didnt have
  enough padding on the top to hold the egg
• The safety broacher is very informative about the
  drill press meets all criteria

Computers can Run a Nintendo game Control a
car engine Record time on the face of a digital
watch

Practically all of the energy on earth comes from
the sun.
Technology comes from the ancient Greek word
technos, which means art
Photography is the process that uses the energy
of light to create pictures of objects
10
Inventors

• Albert Blake Dick and Thomas Jefferson
• Manufactured Mimeograph materials
• Ole Evinrude
• Started working on an outboard motor for small
  boats because his ice cream melted while rowing
  cross a lake
• George Westinghouse
• Improved train brakes as a teenager

11
A patent is a legal document issued by the gov.
that gives a person sole rights to any invention
they develop
Technology makes things happen or makes something
useful --- how to turn the science into something
useful Engineering turns science into useful
items and decide how to make things
12
Science explains why things happen Communication
is the process of exchanging information between
individuals Production making products
available for use Transportation moving people
and products from one place to another
13
Density is the quality or condition of being
dense Mass/Volume ? Heat energy is a form of
energy that is transferred by a difference of
temperature Friction is the rubbing of one
object or surface against another Aerodynamics
is the dynamics of bodies moving relative to
gases, especially the interaction of moving
objects with the atmosphere

Inputs to Technological Systems

• People
• Materials
• Tools
• Energy
• Information
• Finances
• Time

15
Biotechnology --- deals with health, plants,
waste disposal,
the biological-type topics Hydrolectnolgy ---
water Econotechnology --- economics Geotecholo
gy --- geography
16
Four areas of human knowledge that support
technology

• Math
• Science
• Language Arts
• Social studies

Measurement Tools
Ch 8

Measurement is part of a quality control system
A kilometer is longer than a millimeter
19
Seven physical qualities that have measurement
standards

• Distance --- the separation between two points
• Mass --- the amount of matter in an object
• Temperature --- how hot or cold an object or
  place is
• Time --- how long an event lasts
• Number of particles
• Electrical current amps
• Light intensity -- lumens

20
Comparing the qualities of an object to a stated
standard is called measurement The US Customary
measurement system expresses distances in feet
and inches. The metric measurement system
expresses distances in meters and millimeter A
rigid strip of metal with marks on it that is
used to measure linear distances is called a rule.
