This study will help students understand the world around them and how gravity influences
our daily lives
OUR UNIT GOAL: CONSTRUCT KNOWLEDGE TO NEWTON’S 2ND LAW THROUGH AN INTERACTIVE STUDY OF FREE FALL
Unit 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
SIMULATION OF OUR STUDY
OUR LAB GOAL: STUDY FREE FALL WITH USE OF ADVANCED TECHNOLOGY TO CAPTURE AND ANALYZE DATAPre-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
OUR LAB: MODELED FROM OTHERS…

• Students will use many technology touch points to study free fall (cameras, image software, Excel and Powerpoint)
• Collaboration will be stressed to simulate real world environments
• Students will defend their conclusions and observations
