- Effects of Water Dispersal and Conductivity in Microgravity - NASA WING This is the video of a middle school team's experiment in NASA's WING competition. This is an excellent study of fluid forces. Initially, the saline solution top surface is held level due to gravity. When the experiment is dropped, it experiences microgravity and fluid forces curve the top surface of the saline solution in a 'bowl' shape. This raises the outer edges so the saline solution makes contact with the two electrodes in the container and completes a circuit to light the LED. The WING experiments experience weightlessness (aka microgravity or "zero gravity") as they are dropped in the NASA Glenn 2.2 Second Drop Tower. This experiment was designed and built by middle school students in the Hanover Area School District in Hanover Twp., Pennsylvania. More info may be found here: spaceflightsystems.grc.nasa.gov
- Mathis TC-30 Thermal Conductivity Instrument (Archive) From the Archives: The TC-30 was C-Therm's (formerly Mathis Instruments) second generation of thermal conductivity instrumentation which was eventually replaced with the TCi's modified transient plane source technique. The TC-30 could test solids, liquids, powders and pastes across a thermal conductivity range from 0 to 10W/mK and a temperature range from -15 to 50 deg C. With the introduction of the C-Therm TCi Thermal Conductivity ***yzer (/TCi) capabilities of the non-destructive testing were signifcantly expanded to a thermal conductivity range of 0 to 100 W/mK and a temperature range of -50 to 200 deg C. The TCi also eliminated the need for user-calibration as the sensor's are factory-calibrated and fully "plug & play".

- MIT Physics Demo -- Conductivity of Ionized Water A light bulb is placed in series with two copper plates immersed in de-ionized water. Touching the plates closes the circuit, lighting the bulb. When kosher salt is dropped into the de-ionized water, the salt dissolves, causing ions to be dispersed throughout the liquid. The free ions allow current to flow through the water, which completes the circuit and lights the bulb. Most water we encounter in everyday life is not de-ionized and contains impurities with dissolved ions. This is why we know water as a good conductor, and why we shouldn't use electronic devices around a bathtub, for example. See original video on MIT TechTV - techtv.mit.edu

Then, proceed to cut away at the sides of the itrip with a razor blade, seeing as the sides are held togeather with alittle glue. - Step 2: Once the itrip is opened, it's time to find your transmitter wire, which should be a copper wire, diode, or plate on the backside of the unit's circuit board. - Step3: Unsodder theold copper transmitter, and begin to sodder on your new piece of extra long wire to boost the signal. Step4: After soddering the joint, you must create a cut in the side of the plastic shell of the itrip so that the wire can come out of the unit without obstructing it from closing properly. - Thats It!

- About - Conductivity and pH. This video are general informations about conductivity and pH. CONDUCTIVITY Using hydroponics as an example, different crops grow well at different levels of nutrient strength (Electrical Conductivity - EC or CF). Controlling this nutrient strength is all important in providing the best conditions for your crop. Without proper measurement your crop could fail from root burn brought on by too high a nutrient level, or death by natural causes from not receiving the vital elements they need to grow. PH It is important to maintain a hydroponic nutrient solution at a pH level where the elements in the nutrient solution are consistently available to the plant. If the solution is too acidic or too alkaline it can cause lock up a situation which restricts certain elements essential for growth from being absorbed by the root structure.

Florida's East coast is displaying regular levels (300-700). These are hard, tangible scientific test results. Where MY OPINION comes in is AFTER that evidence is established.
