Proposed Project ObjectivesPico-Grid Smart Homes Power Management

In this project, we:1) investigate the different power consumption characteristics

and identify wasted energy within homes.2) identify the main sources of waste within a pico-grid

(Smart House with smart energy management system).3) design a centralized smart energy management system.4) develop an algorithm integrated into the smart energy

management system using communication standards to reduce power consumption. This will allow for monitoring and recording the power flow throughout the pico-grid.

Careers in Energy in the AVID Classroom

• What is AVID?– (Advancement Via Individual Determination) – proven practices in order to prepare students for

success in high school, college, and careers, especially students traditionally underrepresented in higher education.

– methodologies that develop students’ critical thinking, literacy, and math skills across all content areas throughout the entire campus.

• Standards

18


AVID FOCUS STANDARDSInquiry 8-INQ.C. Socratic Seminar and Philosophical

Chairs 8-INQ.C1. Actively participate in and evaluate the process of Philosophical

Chairs and/or Socratic Seminar, focusing on strategies for continuous improvement

8-INQ.C2 Reference text, citing location to support claims and questions8-INQ.C3 Analyze a case in which two or more texts provide conflicting

information on the same topic and identify where the texts disagree on matters of fact or interpretation in a Socratic Seminar or Philosophical Chairs discussion

8-INQ.C4 Evaluate the advantages and disadvantages of using different mediums (e.g., print or digital text, video, multimedia) to present a particular topic or idea in a Socratic Seminar or Philosophical Chairs discussion

19


AVID FOCUS STANDARDS

Organization 8-ORG.C Research and Technology8-ORG.C1 Use technology in assignments and presentations,

particularly in response to guest speaker presentations, field trip experiences and writing assignments

8-ORG.C4 Use the Internet to conduct research in preparation for speeches and essays

8-ORG.C3. Determine validity and applicability of information gathered on the Internet

All Encompassing Questions● What fields of study are available with a future in

Engineering?● Why should Engineering be important to me?● How can I effectively discuss/debate relevance of

Engineering in everyday life, including personal my life?

• Unique Class design

21


Careers in Energy in the AVID Classroom

• Plan for 8th grade AVID class– Demonstrate knowledge of how to pursue Engineering careers – Demonstrate awareness that Engineering is accessible to all – Demonstrate an understanding of relevance of Engineering to everyday life,

including personal life – Demonstrate awareness of opportunities to contribute to society through

Engineering – Demonstrate knowledge of important civic, global, and local problems that

can be addressed by Engineering

• Explanation of summer workshop• Surveys• Lesson Plans

22


Energy and Power Pathway• Purpose of the Pathway

– Introduce high school students to the ever growing and changing field of Energy and Power.

– Give students the skills need to compete in the energy and power job market.

National Standards for Technical LiteracyThe Nature of Technology● SLT.3 - Student will develop an understanding of the relationships among

technologies and the connections between technology and other fields of study.

Design● STL.8 - Students will develop an understanding of the attributes of design.● STL.9 - Students will develop an understanding of engineering design.

Abilities for a Technological World● STL.12: Students will develop abilities to use and maintain technological

products and systems.

The Designed World● STL.16: Students will develop an understanding of and be able to select and use

energy and power technologies

26


Energy and Power Pathway StandardsFoundations of Energy● ENRG-FET-5 Students will discuss the future trends of power and energy. ● ENRG-FET-6 Students will develop, through research, an alternative energy system

that demonstrates their understanding of a unique, as well as an appropriate, approach to energy and power generation.

Generation, Transmission, and Distribution● ENRG-EPGTD-11 Students will demonstrate the importance of following safety

practices for utility workers.

Energy System Applications● ENGR-ESA-1 Students will determine and analyze the relationships between energy,

work, power, and force.● ENGR-ESA-4 Students will differentiate between AC and DC circuits and Apply

Ohm’s Law to Series, Parallel, and Series/Parallel circuits as well as discuss Kirchoff's Law.
