### Free fall (Lynn)

1. 1. This study will help students understand the worldaround them and how gravity influences our daily
2. 2. OUR UNIT GOAL: CONSTRUCT KNOWLEDGE TO NEWTON’S2ND LAW THROUGH AN INTERACTIVE STUDY OF FREE FALLUnit Components: • Kick-off Lab: We will prove Newton’s 2nd Law with Video Cameras and Computer Analysis • We will end the unit with our own “Egg Drop Contest” • Students will share with classmates some ideas on how to apply their knowledge to solving a real world problem
3. 3. SIMULATION OF OUR STUDY
4. 4. OUR LAB GOAL: STUDY FREE FALL WITH USE OF ADVANCEDTECHNOLOGY TO CAPTURE AND ANALYZE DATA Pre-Lab: Set the stage to engage students, introduce the lab, discuss objectives and expectations Phase 1 – Data Capture - Groups will use Video Cameras to capture Free Fall Phase 2 – Video will be studied to collect positions measurements vs time Phase 3 – Data analysis using Excel Phase 4 – Students will share their findings
5. 5. OUR LAB: MODELED FROM OTHERS… Authentic Data Calculated and Graphed using an Excel SpreadsheetData in ExcelSpreadsheet Abisdris, G., & Phaeuf, A. (2009). Using a Digital Video Camera to Study Motion. The Science Teacher, 44- 47.00
