Technical Problem Solving C

[Flavorflav]

There will be instructions, but it couldn't hurt to be familiar with them.

Considering that Science Olympiad has a partnership with Texas Instruments, you probably want to be familiar with TI calculators and Vernier Labpro Probes.

One of the standard questions for Tech Problem Solving for us has been find the number of atoms from in a plate made of some element. How exactly do you find that? Assuming you know the volume of plate, atomic radius of the plate, atomic mass of the element, weight of the plate, weight of 1 mol of the element? I thought I could just divide the weight of the plate by the atomic weight, but I guess not.

If it's elemental, it should be Mass of plate (g)/mass of element (amu)= # of moles. Multiply that by Avogadro's number and that's your answer. If they are really giving you a weight rather than a mass you'll have to convert that first (F/g).

what do you do in this event?
-just curious

[scienceolympiadist]

anything involving math, physics, chemistry is possible

[ktrujillo52]

They just have you do a bunch of basic labs that may involve any branch of science. It's really fun.

oh, it sounds pretty cool

Does anyone know how to do problem #5 from last year's nationals? You can hold the dime out until it just covers the ball, then use the probe to get the distance to the dime (a) and the ball (b), but then what? You would either need the angle or the diameter of the dime, and according to the listed materials you don't have a way to measure either one. Any thoughts?

Does anyone have the past technical problem solving test from nationals that they would like to share? If so could you send me a pm?
