problems and solutions

Holy Cross

Here at Holy Cross, we have a lot of strengths but with strengths comes problems. Some strengths we have are, great technology (iPads, Macs, Computer lab, etc...) which helps students who don't have those resources at home, we also have a bunch of space to expand and build new things to enhance the school.

Problems:

Some problems we have here at Holy Cross are, that we do not have a cafeteria to eat lunch in, another thing is that the walls in the gym are very thin and could be broken with a soccer ball. Some problems are that the older students do not have anything to do when the do get to go outside, something else is that students have to wait until an adult opens the door because they are locked.

Solutions: 

Some solutions for the problems we have are, a simple change, maybe by eating lunch in the Great room, we wouldn't have to worry about kids at recess, to fix the walls is just by adding a slight padding to the walls. To fix the problem with the older students is by simply building or buying a gaga pit, this game would provide fun the kids of all ages, to fix the last problem is that simply making a student ID for the kids that are 5th grade and up that can unlock the doors.

Argon

On the periodic table, argon is in period 3 and group 18. Argon's atomic mass is about 40 kg and its atomic number is 18. Argon is one of the six noble gases, it is classified as that because it is non-reactive to any other elements

Argon was discovered by Lord Rayleigh, an English chemist, and William Ramsay, a Scottish chemist, in 1894. They were conducting an experiment where they took a sample of clean air and removed all oxygen, carbon dioxide, water, and nitrogen, leaving them with one final element of Argon.




Argon is mostly found as a element, especially in the atmosphere since it makes up about 1% of the atmosphere, making it the Earth's third most abundant gas. Argon does have a compound called Argon Fluorohydride ( HArF), but it was not discovered until  the 2000's.



To get argon in its pure form, you would have to boil liquid air (pressurized) until the liquid nitrogen would boil out at 77.3 degrees kelvin.



Today argon is used for, thermal insulation in windows, incandescent lighting, inflating dry suits in scuba diving, and in fluorescent light bulbs.
