At the end of the year, students get a chance to be the scientists in several projects. One of my absolute favorites is the water bottle rocket. The video shows the general design of the rockets and several launches. What I love about the project is that they chose one variable to change that will increase flight distance. Variables include fin shape, fin size, fin placement, volume of water, etc. I also love that there is not just one design that works. Here is the handout that I give to students.
