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.

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.
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 helpolyweeah wrote: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?

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.olyweeah wrote: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?
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?blindmewithscience wrote: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.

Also, take a look at this (from the rules sheet). If you have an Nspire, definitely download the relevant ones and go through them.
