Big Ideas

Technology is created, used and modified by humans.
Concepts

Creating optimal solutions under constraints are a primary component of technological problem solving (e.g., tools/machines, materials, information, people, capital, energy, and time).

Decisions about the use of products and systems can result in expected and unexpected consequences.

Decisions about the use of products and systems can result in known and unexpected consequences.

Human decision making (e.g. Human needs and wants plus cultural considerations) drives the selection and/or use of technologies.

Science and technology are interconnected.

Science is the study of the natural world and technology is the study of the human designed world but both are inextricably connected.

The goal of technology is to meet human needs and wants.

The study of the impacts of technological systems enables us to plan and direct technological developments.

The use of technology involves weighing the trade-offs of the positive and negative effects.

Understanding technological systems help us plan and control technological developments.

While science is the study of the natural world, technology is the study of the human designed world.
Competencies

Demonstrate how technological progress promotes the advancement of science, technology, engineering and mathematics (STEM).

Describe the complementary roles of scientific knowledge and technological application.

Describe the nature of technology and the consequences of technological activity which impact society and the world.

Differentiate between the study of science and technology.

Explain how making informed decisions about the development and use of technology may have known and unexpected consequences.

Explain how technology has and can change the human condition throughout time.

Verify that engineering design is influenced by personal characteristics, such as creativity, resourcefulness and the ability to visualize and think abstractly.

Rationale

What is the correct model of an atom?
