Science Project Catapult with Experiment Guide.



Designed especially for school science experiments, this catapult/trebuchet stands 15 inches long, 11 inches wide and 10 inches tall at the axle. The arm is 16 inches long and can hurl a marble up to 30 feet. This machine is designed to be configured and fired in a multitude of ways to test different theories about efficient projectile motion.


Which works better, a sling, or a spoon-type arm? Is a counterweight better than a spring? What about wheels, some people think wheels make a trebuchet better, others disagree. Now you can test all those things, and any combination of them as well, and come to your own conclusions.


Ideal for Science Olympiad, Six Sigma, Design of Experiment (DOE) and other statistical methods courses, this kit even comes with a 23 page booklet including ideas, experiments, tips and tricks you can do with the kit, from basic kid-friendly concepts all the way up to college level material, including how to effectively organize and display (graph) your results.


The experiment guide includes:

  • 13 steps to a successful project
  • The science of projectile motion
  • Definitions of kinetic and potential energy
  • Effects of configuration changes
  • Safety issues
  • Useful equations (basic math)
  • Advanced calculations (trigonometry)
  • Standard deviations
  • Graphing results
  • Five different experiments with questions to answer for each
  • Data Log sheets
    And more!


    The kit includes everything you need to build and operate the kit. The only thing you need to supply is a standard Phillips screwdriver and a few rubber bands. The kit is easily convertible from any configuration to another in a matter of seconds. It's a fantastic learning platform!


    This product is manufactured in Canada.

    Notes:
    Why should a kid
    build a catapult?

    Because the world needs good engineers and scientists, and because the kids who will grow up to become engineers and scientists need a way to get hands-on experience with physics, math and engineering.

    In this age of 200-plus channels of TV, the Internet and computer games, kids are also spending far less time building tree houses, tinkering with engines, or designing downhill racers. We believe those are important skills to have. They help form the basis for good problem solving skills and an innate understanding of the real, physical world that you just can't get from a computer game, no matter how good its physics simulation software is.

    Ballistic motion was one of the key players in the development of the science of physics. The word "engineer" even originated as the builders and designer of Siege Engines

    Why is a budding engineering student expected to take a year or two of calculus in high school, but she isn't expected to have any real-world experience in building or working with machines and materials? Pencil and paper (or computer screens) are only one part of the learning experience. Where will she apply all of the stuff she learned in geometry and trig? Without physical projects to touch, feel and see, the lessons become abstract, their utility questionable.

    A catapult project gives students a chance to see that science and engineering really can be fun, and it's a lot more than just numbers on paper. The real payoff for an engineer is in the field, where she can see and enjoy the results of her ingenuity. And it may seem counterintuitive, but engineering projects not only help kids learn math and science, they are also great at getting kids back outdoors, away from the massive over-exposure to video games, TV and the Internet.

    Why all this interest in getting kids to study science and engineering? Because it's important to our society, and it's great mental cross training regardless of what field of work the kids eventually go into. Most people develop a sense for what they want to do in life while they are still in high school or even earlier. A catapult project is fun and interesting enough to inspire some kids to study the science behind how they work, and then go on to become the engineers and scientists of tomorrow.
