1 Speed Bumps FORCE & ACCELERATION NEWTON’S 2 ND LAW

2 Why do you think some collisions have big forces and other collisions have small forces? What do you think influences the size of the collision force? ENTRY TASK

3 Design an experiment to identify the affect one variable has on collision force. SPEED BUMPS LAB

4 HOW COULD WE MEASURE THE SIZE OF THE COLLISION FORCE? Note: Consider the materials available when answering this question

5 If you test ___________ WHAT VARIABLES MIGHT WE NEED TO KEEP THE SAME FOR THE VALIDITY OF OUR EXPERIMENT?

6 1.Write an investigative Question (this should be similar) 2.Develop a hypothesis (this can be different) 3.Show Ms. Barga ALL at the same time 4.Then explore the materials to develop a procedure. 5.Practice your procedure and create a data table for collecting the information you need (you are NOT collecting official data YET) 6.When your procedure is clear and consistent and you have a data table, Show Ms. Barga 7.When She Approves, WRITE DOWN YOUR PROCEDURE 8.Use pictures to help you write less words!!! DESIGN YOUR EXPERIMENT

7  Finish writing down your APPROVED procedure.  Be clear, complete AND concise (short)  Prepare 3 blank Data Tables for collecting data on Thursday (Each person in your group will need 3 blank data tables)  Science Fair Assignment #1 DUE 10/01/15  Spend 1 hour researching / exploring ideas for your science fair project HOMEWORK:
