You can, but you need to use 2 of the materials provided as far as I remember.

It depends; you're allowed to bring certain materials in. A good kit to have ready should include the following: A ruler or two, some extra pencils, goggles, clipboards, a timer and a calculator. Your proctor might only allow some materials in, and the rest you should place elsewhere. A ramp is something I wouldn't bring to a competition.

Hey, I didn't mean bringing a ramp, I meant using what we brought in as a supplement to our experience. Like rolling things down our meterstick or dropping our pens to test gravity.

Oh I see what you mean. That situation you could likely get away with it. Sorry for the misconception!

Just keep in mind, you'll be tiered if you don't do an experiment related to the topic (4.f.) I would hope that most supervisors will provide adequate materials to test the topic, and using a meterstick as a ramp, or the stopwatch lanyard as a pendulum, may be going too far "outside the box" to adequately address the topic. It's not prohibited, but I wouldn't encourage that as Plan A. It does make for a good back-up plan though.

So, I do variables and every time I do the dependent variable I always get a point off for "dependent variable has to be operationally defined"

State is tomorrow, could anyone explain to me what operationally defined means?

To get "operationally defined" points, you need to explain not just what the variable is, but HOW you're going to set it up (IV) or measure it (DV). For example, if the IV is the height of a ramp, you may operationally define it by explaining how you will stack one, two, or three textbooks to create ramps of different heights. If the DV is the time it takes a ball to roll, you may operationally define it by explaining exactly when the timer starts and stops the timer.

Do you guys use up all of your time on this event or do you have time to spare.I ask cuz we are always cutting it close while other teams leave early. :?:

Personally, we are always working until the last possible moments, but it really depends on the working style of the team and how fast they can do an experiment. It doesn't really matter how much time you take as long as you have a good report and you've finished everything.
