http://www.ck12.org Chapter 2. Scientific Research and Technology
- Technological design is the development of new technology. The design process is based on evidence and
logic. - Technology and science have different goals, but each helps the other advance.
- The problems of society generally set the direction of technology. New technologies, in turn, may make
people’s lives easier or healthier.
Lesson Review Questions
Recall
- Define technology.
- What do engineers do?
- List the steps of the technological design process.
Apply Concepts
- A team of engineers is designing a new type of car. What are likely to be some of the constraints on the
design?
Think Critically
- Compare and contrast science and technology.
- Relate technology and society.
Points to Consider
Nanotechnology manipulates atoms and molecules of matter.
- What is matter? What are its characteristics?
- Do you think all matter consists of atoms and molecules?
