This curriculum-embedded science performance task is related to the content standards and expected performances for Grades 9-10, as described in the Core Science Curriculum Framework, under Scientific Inquiry, Literacy and Numeracy, Strand I – Energy Transformations.

Targeted Content Standard

9.3 - Various sources of energy are used by humans and all have advantages and disadvantages.

Targeted Scientific Inquiry, Literacy and Numeracy Standards

D INQ. 2  Read, interpret and examine the credibility and validity of scientific claims in different sources of information.

D INQ. 9  Articulate conclusions and explanations based on research data, and assess results based on the design of an investigation.

D INQ. 10 Communicate about science in different formats, using relevant science vocabulary, supporting evidence and clear logic.

Learning objective:

Students will graph energy trends in Connecticut over several years and based on their research, they will explain the advantages and disadvantages as it relates to one trend in energy use.

Materials:

Excel program

Graph paper and ruler (alternative)

Considerations:

If access to computers or the Excel program is difficult, the graphing portion may be done by hand.  Not all students are equally comfortable with Excel worksheets and the related program features.  Tutorial programs are available online and include features that will assist students in the conversion of units and graphing from spreadsheets.  Tutorials on the use of Excel programs may be found at the following websites and many others:

Should you prefer to have students work in metric units, you will want to provide them with the following equalities:   1 kW-hr = 3600 kJ = 2544 Btu (British thermal unit).

Two alternative Excel sheets are provided for differentiation purposes or you may use one of your own design.
