The document provides guidance for scientific investigations for a course requiring a 10 hour investigation and 6-12 page write up. It recommends investigations include a purposeful research question, scientific rationale, and adhere to standards of previous assessments. Suggested tasks involve hands-on labs, spreadsheet analysis, extracting and graphing data from databases, or combining experiments with simulations. Traditional hands-on experiments could also be paired with simulations or use old apparatus and particular sensors. System-based designs, sports analyses, and simulations using programs like Algodoo or Interactive Physics are additionally proposed.
