﻿ 1. Choosing A Project:

TOPICS THAT INTEREST ME: CURRICULUM CONNECTION:http://www.instructables.com/id/knexmarble-launcher/ im am going to get the idea from this but expand and add my own touch to the final shooter Force and Motion What will the distances be when I shoot the gun when i use different rubber bands INDEPENDENT VARIABLE: Marble Gun

DEPENDENT VARIABLE: Different Rubber bands

2. Investigate the Information:

 NOTES/FACTS: I saw that the rubber band is pulled back and shot and there is a pattern with it

NOW THAT I'VE DONE SOME RESEARCH, I PREDICT THE ANSWER TO MY QUESTION WILL BE:That the smaller stronger rubber bands will send the marble further than weak ones that are stretched out.

3. Plan A Procedure: For my project I will make my gun to the specifications of the website and will shoot it with different rubber bands and calculate the distances

4. What I'll Need:

 I have these: I need to locate these: Knex pieces i can figure how many I will need

5. Keeping Track - Proposed Data Sheet

6. Analyze It All
