This resource for Grades 7-9 provides turn-key lessons for teaching a two-week unit on the use of wind energy to generate electricity. The first week is a study of the history and science underlying wind energy; the second week features an engineering design project for students to build their own windmill blades. In the culminating activity, students take on various community roles to decide where to locate a wind farm. This resource includes every component required for immediate classroom use: lesson plans, illustrated lab procedures, pre and post-test assessments, age-appropriate background information, worksheets, graphics for classroom projection, and student guidebooks. The NEED Project is a national initiative to bring innovative curriculum materials in energy education to teachers and learners from the primary grades through college. The windmill blade design activity requires purchase of a kit costing $450.00. All other activities can be performed using materials easily acquired from hardware stores or science supply houses.

Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6—8 texts and topics.

By the end of grade 8, read and comprehend science/technical texts in the grades 6—8 text complexity band independently and proficiently.

Write arguments focused on discipline-specific content.

Conduct short research projects to answer a question (including a self-generated question), drawing on several sources and generating additional related, focused questions that allow for multiple avenues of exploration.

Draw evidence from informational texts to support analysis, reflection, and research.

Construct viable arguments and critique the reasoning of others.

Use appropriate tools strategically.

Understand ratio concepts and use ratio reasoning to solve problems.

Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.

Use ratio reasoning to convert measurement units; manipulate and transform units appropriately when multiplying or dividing quantities.

Reason about and solve one-variable equations and inequalities.

Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set.

Solve real-world and mathematical problems by writing and solving equations of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.

Solve real-life and mathematical problems using numerical and algebraic expressions and equations.

Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), using tools strategically. Apply properties of operations to calculate with numbers in any form; convert between forms as appropriate; and assess the reasonableness of answers using mental computation and estimation strategies.

Analyze and solve linear equations and pairs of simultaneous linear equations.

Solve linear equations in one variable.

Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.
