Reading assignment one

Mentos and Soda The first thing that I know is that when you put Mentos in soda the soda erupts out of its bottle. The second thing that I know is that most people use diet coke for the eruption to happen. They don't usually use any over kind of soda for the experiment. The last thing I know is many people like to try to make the eruption happen. The first thing that I learned was the amount of CO2 one Mentos can dissolve is based off the amount of CO2 pressure pushing of the surface of the soda. The second thing that I learned is that the pressure goes down greatly when you open the bottle on soda. The last thing I learned was the warmer the soda is the faster the fizz goes away. That is why when you put a ice cube in the soda the fizz stays much longer.

Steven, Did you ever notice that when you first put ice in a soda it makes it fizz? Same idea as Mentos and coke. Good post! 5 stars!. MW

Video assignment 2

Distillation You can use Distilation to seperate the liquid oil. When you use this process you get hydrogen and carbon out of it. The hydro carbons boil at around 40 degres celuis.In fractional disalization you break down a mixture into atoms and particles. In the commercial business they use fractional disalization. They do it on a big scale. At different layers of this tank different solutions are collected. Some of those solutions are gasoline, fuel oil, kerosene or jet fuel, desel fuel, and residue also known as tar.

Steven, The process is called distillation -not chromatography. 4 stars. MW

Reading assignment 3

Motion Detectors Motion detectors are used in three different ways. The first way it works is that it sends infared radition to a cerian area. If this area is some how blocked by an object then the light goes on. The second way is sends out waves like the ones in a microwave to a certain area. If those waves are blocked then the light goes on. The third way is it listens for your warmth. It is dected when warmth or radition is detected. It is all photo-electronic connection. The first person to observe this was German physicist Heinrich Hertz. He found this in 1887.

Steven, Pretty sparse. Please follow the rubric and the prompt. (3 things you knew and 3 things you learned!) 3 stars. MW
