• Explain how the use of common household tools is determined by their design.

A tools design and the purpose of the tool are closely related.

• Use various tools (e.g., magnifiers, thermometers, or rulers ) to improve observations and measurements.
• Identify the technology used in different occupations.

Scientists use tools for better observations.

Balance can compare the mass of objects.

Thermometers measure temperature.

Magnifying glasses make objects appear larger.

Men and women have made a variety of contributions throughout the history of science and technology.

Science and technology have been practiced by people for a long time.

• Propose a solution to a simple problem.
• Implement the proposed solution.
• Evaluate the implementation.
• Communicate the problem, design, and solution.

Technology can be used to build or improve something.

Tools are a part of technology and they are used to do things better, easier, and things that could not be done otherwise.

Tools are used to make better observations and measurements.

Some objects occur in nature (natural objects); others have been designed and made by people to solve human problems and enhance the quality of life (design or man made).

Drawings and simple models can be used to plan technology.

People help other people to make and improve things

People use objects and ideas to solve problems.

People can't always make what they design.

Some materials are better than others for making particular things.

Materials that are better in some ways (stronger, cheaper) may be worse in other ways (heavier, harder to form).

Steps are usually involved in making things.

Tools are helpful when making things.

Some things can't be made with out tools.

Each kind of tool has a special purpose.

A variety of different materials (paper, cardboard, wood, plastic, metal) can be used with a variety of tools (hammers, screwdrivers, clamps, rulers, scissors, hand lenses, and audio-visual equipment) to make simple constructions.

People alone or in groups are always inventing new ways to solve problems and do work.

Tools and the ways people do things affect all aspects of life.

Tools and ideas are technology.

When people want to build something new they should consider how it might affect people.

• Classify an object as either natural or manufactured.

Men and women have made a variety of contributions throughout the history of science and technology.

Science and technology have been practiced by people for a long time.

New ideas and inventions continue to affect people.

Engineers and scientists work together, using technology to help explain and solve today’s problems

• Identify problems for technological design.
• Design a solution or product.
• Implement a proposed design.
• Evaluate completed technological designs or products.
• Communicate the process of technological design.

The benefits of science and technology are not available to all people.

There are practical limits of the use of technology, including cost, time and availability of materials.

Technology for a given situation or problem is limited by the creative wisdom of humans, the availability of time, and availability of resources.

• Distinguish between scientific inquiry (asking questions about the natural world) and technological design (using science to solve practical problems).
• Describe how science and technology are reciprocal.
• Assess the avoidable and unavoidable limits of a technological design.
• Recognize that solutions have intended and unintended consequences.
