Investigating Force - 2

We used paint and straws to investigate the effect of force. We first blew lightly into the straw that was full of paint, then we blew a little header, and finally we blew very hard. We noticed that the harder we blew, the larger the splatter made by our paint. 

At the end of the investigation, we used just the force of our air to blow the paint around. This helped us with Newton's Fiest Lawe of Motion, the law of inerti, because the paint was at rest until the force of our air was pushed upon it causing the paint to move.
