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
