📝 Catapult Investigation Plan

Students draft their full methodology in their Catapult Investigation Research Notebook. The plan includes: research question, hypothesis with energy-based rationale, identified variables, materials list (popsicle sticks, rubber bands, marshmallow or pom-pom projectile, meter stick, protractor), step-by-step procedure, minimum of 5 trials, data table template with units, and at least one quality control measure (e.g., consistent pull-back distance).
