A 9-page unplugged STEM rotation pack on solar array design, watt output math, side-elevation blueprints, smart grid flowcharts, and blackout case studies.

Bring renewable energy engineering, power output math, side-elevation technical drawing, smart grid computer logic, and real-world disaster case studies into your classroom with STEM Station Pack 3: Solar Power & Smart Grid Engineering! This 9-page printable resource is completely unplugged (no screens or computers required for students) and designed for a smooth 60- to 75-minute rotation lab using standard, low-cost classroom supplies.

What Is Included in This 9-Page Pack?

Page 1: Teacher Setup & Master Guide: Master materials checklist, classroom station map, setup instructions, and rotation timing tips.

Page 2: Student Answer Sheet (1-Page Master Handout): Single, organized handout for students to clip to a clipboard and carry from Station 1 to Station 5.

Page 3: Station 1 Sign (Solar Collector Build Lab): Students construct a solar panel collector array prototype out of cardboard and foil, test panel tilt angles with a lamp (“Sun”), and calculate surface area.

Page 4: Station 2 Sign (Grid Budget & Power Output): Students calculate component costs from a price list, compute daily watt output based on surface area, and determine their custom Grid Efficiency Score.

Page 5: Station 3 Sign (Solar Array Angle Blueprint): Students draw a precise side-elevation blueprint showing panel plane, ground line, and light ray alignment while explaining seasonal sun path variations.

Page 6: Station 4 Sign (Smart Grid Algorithm): Students trace a conditional logic flowchart (If/Then) to direct excess solar energy into battery reserves or prevent transformer overloads.

Page 7: Station 5 Sign (Real-World Case Study): Students read a short technical passage on The 2003 Northeast Blackout, learning about tree-line interference, alarm software glitches, and cascading power failures.

Page 8: Detailed Teacher Answer Key: Fully worked math examples for cost and watt calculations, blueprint verification, logic responses, and case study guidance.

Page 9: 10-Point Master Grading Rubric: Clean, single-page rubric assessing every station on a 0-to-2 point scale for fast, objective grading.
