Water Bottle Blast Off! Back to Blog Articles

  • Posted on Jul 26, 2012

Earlier this week, students in Sara White’s physical science class launched their water bottle rockets as a part of a week long project where students built them around 2 liter bottles.  After accumulating pop bottles for several weeks, students built and designed the rockets in class with hopes that their rocket would fly the best.  The blast off was the conclusion to a unit that looked at Newton’s Three Laws of Motion.  You know what they are, right?

As a quick science lesson, here are Newton’s Three Laws of Motion along with an explanation from Shawn Hill, a student in the class.
1. An object in motion will stay in motion and an object at rest will remain at rest unless acted upon by an outside force.  This is the main law that applies to the water bottle rocket project.
2. Force equals mass times acceleration (F=MA).  Shawn Hill, a student in the class, simplified this law by explaining that “the motion of an object is determined by how big the object is and that will result in how fast it goes.
3. For every action, there is an equal and opposite reaction.  This is the law that says that no matter what an object does, the reaction will be able to cancel it out.

It was an enjoyable and unforgettable science class.  By using hands on instruction, the students will have a more likely chance of understanding and seeing Newton’s Three Laws of Motion in daily life.
