Anyone look over the SOINC store's updated TPS CD-ROM? What is on it and is it worth buying, in your opinion? I don't want to purchase a disc only to find that it's basically what you can easily find (and for free) with a little time doing some internet searching.

My understanding on rule: It will be about forensic patterns, physical, about crime for both stations, and we collect data and make predictions. Is that right? Also, what is a colorimeter and a CBR2??

Wikipedia wrote:A colorimeter is a device used in colorimetry. In scientific fields the word generally refers to the device that measures the absorbance of particular wavelengths of light by a specific solution. This device is most commonly used to determine the concentration of a known solute in a given solution by the application of the Beer-Lambert law, which states that the concentration of a solute is proportional to the absorbance.

So since this year's topic deals a lot with physics stuff(motion/velocity/wavelength), its going to be more of a physics event?

also what is Dual force?

Vernier wrote:The Dual-Range Force Sensor is a general-purpose sensor for measuring pushing and pulling forces. It can be used in a broad range of ways: as a replacement for a hand-held spring scale, mounted horizontally on a dynamics cart to study collisions, mounted on a ring-stand to measure forces in a vertical direction, collect data from two Force Sensors simultaneously to study Newton’s Third Law.

If anyone is like me and is not sure about how the allowable probes for this event might be used in crime scene analysis, take a look at this link.

How in the world do you prepare for this event? I'm incredibly excited for it, but my partner and I have no idea how to start... Any ideas?

Speaking of that, I'm planning to take this event next year. Is there anything that I need to know (because my high school sucks with event help :roll: )

Take a look at each "topic" and memorize formulas and theory for each one.With the colorimeter, know Beer's law and measurements of concentrations. With the temperature probe, take a look at thermodynamics in physics (Q=mc deltaT, U=Q-W, etc.). And for the Force and Motion probes, I suggest kinematics, forces, energy, and momentum. Hopefully not forgetting anything right now.
Also, take a look at this (from the rules sheet). If you have an Nspire, definitely download the relevant ones and go through them.
Nevada state SO occurs on tau/2 day. Support the correct mathematical constant with all tauists.

Thank you! I already downloaded all of the case files, but I need to *beg* my teacher to order at least some of the probes but they're uber expensive (just the EasyLink to connect the sensors costs $59...) and my district sucks. Quite honestly, we probably won't need to worry about the sensors until state, but then everyone will be studying for extra events (this is my districts 2nd year, and we only do like 15 events at regionals... And this year I'm moving on from B to C so it's like all new) so it's better to do it now. Do you (or anyone else really) have any ideas of what we can do until we get the necessary equipment?
