Matchstick Rockets

Posted on: May 29, 2008


This is a favorite of the students. After studying Newton’s Laws of motion, we spend a day making rockets from paper match sticks. The process is simple, tear out a paper match, cover the top with a small piece of tightly wrapped aluminum foil, heat the match with a lighter and watch it launch.

Students will typically make at least three of these in a class period. Most go no more than an inch or two, many doing that backwards. Last year one match went 26 feet. This year, I believe the record was 18 feet. Credit goes to Richard White for sending me this last year.

The directions call for making the exhaust tube with a paperclip. That hasn’t worked well for us, the hole is too big. I’ve seen other directions that use a pin. I haven’t tried it with a pin, but I’d like to. In class, we simply wrap the tip tight and count on the gases finding their own exit.

Note: This is an outside activity unless you have a really well ventilated lab, which I don’t. Also, spend $5 on a BernzOmatic lighter. You can get it from Walmart. Aim for a day with very little wind otherwise you will have a hard time keeping the rockets on their launcher and even harder time getting them lit.

What’s New in 2013/2014?

Every year brings a change, this one is no exception.

I will be picking up the sophomore honors Algebra II class to keep them separate from the juniors. This should help accelerate them and put them on a stronger track towards Calculus. Looks like there will be only one section each of Physics and Calculus, but still two of Robotics & Engineering.

Hot topics this year are going to be the Common-Core Standards, Standards-Based Grading (SBG), improving AP Calculus scores, and somehow adding Python, maybe as a club.

Just a quick poll to help me understand who is stopping by my blog.

Yeah sure, lots from America, but look who else is here…

If you are badly in need of more email or for some reason jonesing for a physics fix, enter your email address so I can bother you with my newest rant on science.
