Holy Cross engineering project

 
Holy Cross is a warm safe environment to be in. Some strengths are that we have wonderful staff, who are passionate about learning and God. We have both a middle school, elementary school, and a preschool. We have a church with us so we get to go to chapel on Wednesday. We have a play ground that is great for the little kids, but sadly some of elementary, and middle school don't get to enjoy they playground like they do. Middle schoolers found a game that they like, called Gaga. Gaga is a fun game involving a gaga pit. Teaching kids is easy to do we just have to be able to build it. After that it is lots of fun!





This is what the pit would look like

Another problem is the middle school lockers. Now that we share lockers for backpacks there is no room. A way to fix that is by getting hooks to put our backpack and lunch boxes on. It will help things get spaced out keeping things separate. It is more space then the tiny little lockers, that don't have enough room for all those bags.










This is what the hooks could possibly look like


Another possible problem is the doors locking. It gets tough when we have to stand at the door for so long waiting for someone to unlock it. Sometimes there isn't even a person there to unlock the door. I think a solution for that is to have a code, that we learn and can type in for easy access.
 



 

This is what a simple keypad would look like to use

Xenon




On July 12, 1898, Sir William Ramsey and Morris M. Travers discovered the element Xenon. Xenon was discovered shortly after their discovery of krypton and neon. They found xenon in the residue of left over components of liquefied air. This experiment of liquefied air is what caused them to figure out the element of xenon.

Xenon can be found in strobe lights, xenon lights, and types of car head lights. While xenon is an element, it can be paired with multiple other elements like fluorine, platinum, and oxygen, creating compounds.
 

Xenon has 54 protons and electrons, and 77 neutrons. Xenon is in period 5 because the electrons occupy five rings. Xenon is part of group 18 because it is a Noble gas. Xenon is usually unreactive, but sometimes can have chemical reactions, such as the formation of xenon and hexafluoroplatinate. Other wise it is like most noble gases, unreactive.
 
 
 
Fun Facts:
  • Xenon produces brilliant white flashes of light when it is excited electrically and is widely used in strobe lights.
  • The light emitted from xenon lamps are used to kill bacteria and power ruby lasers
  • Due to the high atomic weight, xenon ions were used as a fuel in experimental ion engine aboard the space probe Deep Space 1.
  • Xenon gases has recently been used in fireworks
