📝 Big Falls Investigation Plan

In small groups, students complete a large planning poster that includes: their team question, prediction, materials (e.g., sand, gravel, coffee filter, clear cups), step-by-step picture procedure, what data will be collected (tally chart, drawing, photo), how many times they will test (at least 2), and one way to keep the test fair. Students use drawings and teacher-scribed labels. They add a simple safety note (e.g., "no drinking water").
