COURSE DESCRIPTION

 

Principles of Technology is a hands on course geared for the broad majority of high school students.  Concepts should be taught within the context of how they relate to four energy systems: mechanical, fluid, electrical and thermal. 

 

**Technology /  Vocational credit may also be earned for this course.

Alaska Science Performance Standards

 

A 2.  Students describe and explain a common chemical reaction including atomic chemical bonding, and reaction rates.

A 3.  Students use secondary research to develop models that explain the origin and continued development of the solar system, galaxy, and the universe.

A 4.  Students explain tides, weather, seasons, and phases of the moon including the appropriate concepts of gravity, the Coriolus effect, role of the atmosphere, and Earth’s rotation and revolution.

A 6.  Students explain common examples of linear and rotational motion using Newton’s Laws of Motion.

B 1.  Students collect, analyze, and interpret qualitative and quantitative data, develop models, and suggest further experimentation to investigate and explain everyday phenomena in their world.

B 2.  Students conduct primary scientific research and use sophisticated instrumentation technology to design, modify, and conduct a series of experiments related to a multifaceted problem in the natural or designed world.

B 6.  Students examine laboratory and community safety procedures, identify how an individual affects the safety of the group, and practice safe behavior in the classroom and laboratory.

C 1.  Students can differentiate between facts, observations, concepts, principles, laws, and theories, as used in science publications.

D 1.  Students investigate a regional or global issue; identify and evaluate the current solutions.

D 6.  Students work collaboratively to design a solution to a problem, develop an evaluation tool to measure the effectiveness of their solution, and make revisions to the original solution based on the information collected.
