Water Bottle Rockets activities are a fun way to help teach educational concepts of science, technology, engineering, math (STEM), and are ideal for teaching Newton's laws of motion while having fun!
What makes rockets fly straight? What makes rockets fly far? Why use water to make the rocket fly? Students are challenged to design and build rockets from two-liter plastic soda bottles that travel as far and straight as possible or stay aloft as long as possible by exploring key rocket design concepts: center of drag, the center of mass, and momentum and impulse. Diffraction, Polarization & Interference.Playing child will notice the difference in the launch speed of a single ball and that of two or more.Īll parts of the contraption made of plastic,įour wiffle balls made out of. Of conservation of momentum when multiple balls are stuck in the middle tube (happens when you get a score of 1). What you Learn: Gravity and Conservation of Momentum: of course it's a great toy to observe gravity, because theįorce with which you press the button will determine how high it goes, and how fast it falls. The front of the toy is made of clear plastic so all the wonder can be seen. On top of the contraption is a series of five funnels (with varying difficulties of entry corresponding to the score they represent), all of which are connected to tubes so the balls that enter them can be re-launched from the center. Once that ball flies up the tube, the next one in line (determined by how many are in each chamber) slides into place, so you can have more than one ball in the air at a time, and can even send them on a collision course. The weight of the ball resting in the bottom of the tube keeps the lever down, and pressing the button sends the ball skyward. How it Works: Underneath the button is a simple lever.
