TEKS Correlations:
This lesson, as published, correlates to the following TEKS. Any changes/alterations to the activities may result in the elimination of any or all of the TEKS listed.
Principles of Manufacturing:

130.322(c)(3)(B)(C)
...describe system differences such as open and closed; and
...describe how technological systems interact to achieve common goals.
Interdisciplinary Correlations:
Physics:

112.39(c)(2)(A)(B)(C)(D)
...know the definition of science and understand that it has limitations, as specified in subsection (b)(2) of this section;
...know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories;
...know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but may be subject to change as new areas of science and new technologies are developed;
...distinguish between scientific hypotheses and scientific theories;


112.39(c)(3)(D)
...explain the impacts of the scientific contributions of a variety of historical and contemporary scientists on scientific thought and society;
English:


110.42(b)(7)(A)(I)(J)
…establish a purpose for reading such as to discover, interpret, and enjoy;
…use study strategies such as skimming and scanning, note taking, outlining, and using study-guide questions to better understand texts;
…read silently with comprehension for a sustained period of time;
Teacher Preparation:
Teachers should review the definitions, all supporting documents such as PowerPoint presentations and notes. Teachers are also encouraged to conduct their own research on lesson material.

ASK: How does a refrigerator keep food cold?
ASK: After a product is manufactured, how do we protect and preserve it until it is purchased by the customer?
Show: A web page, photos or online video of a typical food or medical manufacturing process.
SAY: In modern times we have found innovative ways to use technology to greatly enhance our lives and remove much of the manual labor from our day to day living.

Guided Practice (LSI Quadrant III):
Using Matching Definitions handout, students will pair-share and teach each other the terms and definitions. They may do computer-based research to look up the meaning.
Independent Practice (LSI Quadrant III):
Students will complete Warm-up Activity, doing computer-based research to look up and match the meaning of words on the handout, writing out definitions on a sheet of paper.
Summary
Review (LSI Quadrants I and IV):
Question: Most of the questions should involve definitions.
Answer: They can write or answer orally.
Question: What type of system (open or closed) is a refrigerator and why?
Answer: Closed, because the thermostat controls the temperature.
Question: Why is the cooling system on an engine important to the overall operation of the automobile?
Answer: If the engine overheats, the entire automobile might shut down.
Evaluation
Informal Assessment (LSI Quadrant III):
Oral question/answer. Students will complete definitions teacher has on the board from terms in the definitions handout. The quiz may be used as a means of informal assessment.
Formal Assessment (LSI Quadrant III, IV):
No formal assessment in Part 1 of this lesson.
Extension
Extension/Enrichment (LSI Quadrant IV):
1. Students can write a paper comparing a household refrigerator to a large industrial freezer.
2. Students can conduct research on the internet, create a PowerPoint presentation and give a classroom presentation comparing the differences in features on a 1920’s automobile and a 2010 automobile.

What process is used to turn ideas into products?
Manufacturing activities are based on what process?
What is the purpose of the packaging process?
11
Define the 3 key aspects of an Open Loop System.
ANS: Input - ideas, resources and desired results
Process - changing ideas into products
Output - the results of the process
What is the difference between Open and Closed Loop Systems?
ANS: Closed loop systems go a step beyond open loop systems by providing a way to monitor the output, compare it to the input and then make adjustments to control the desired output
