Path to the Periodic Table
In this activity we first cut out small cards that each represented elements of the periodic table. We then arranged them in a way that made sense to us, so first I arranged them alphabetically, but that didn't really make any sense to me so I did it again only this time I used the atomic mass going from least to greatest. After that, we were given an extra set of cards to add to our tables. I added these cards in the correct places that they needed to be and then compared my periodic table to the real one. They actually looked the same!
Ionic Bonding Activity
In this activity, we took two elements from the periodic table and combined them to form ionic bonds. The elements that we used were Sodium, Chlorine, Beryllium, Fluorine, Lithium, Oxygen, and Phosphorus. We followed six steps to make these Ionic bonds. First, we wrote the symbol for each element, then we used fruity pebbles to create the Lewis Structure for each, next, we drew arrows to show the transfer of electrons and move the fruity pebbles to the new location. The fourth step was to move the fruity pebbles and used the colored pencils to show the placement of electrons in the compounds. Then, after determining the charge for each ion and writing the formula using the oxidation number. Finally, you make sure the sum of the charges, or the oxidation number, was zero and we wrote the chemical formula. We repeated this process for every pair of elements until we completed the whole worksheet.

Green Chemistry
Green Chemistry is Chemistry that looks at the design and implementation of chemical technologies, processes and services that are safer and use less energy. Green Chemistry is just much more efficient for us to use in our environment while still keeping it safe. Using new Green Chemistry innovations give us the products and processes we need that will still meet demands while improving sustainability, giving us more efficient products and keeping everything overall cleaner. This way, we still meet the expectations of these products while improving their overall efficiency. Green Chemistry is just a form of Chemistry that won’t affect the world in a negative way and it won’t pollute the air and environment.
The Hartford Circus Fire
On a summer day in the Southern end of Hartford, is where a terrible fire took place in The Great Hartford Circus. The owners of this circus had originally wanted a safe form of the waterproofing agent to use for their acts that involved fire. Unfortunately, they weren’t granted the use of it so they had to rely on a mixture of paraffin wax and gasoline which had worked well before, but had also caught many fires before this one. The mixture of paraffin wax and gasoline was extremely flammable, but it was the only substance they could use if they wanted to hold shows while it was raining. This would work because the molecules of water would rather bond with themselves instead of bonding with a nonpolar wax surface such as the one they were using. This is why the water would just land in droplets on the tent and roll off. Because of the amount of paraffin and gasoline that was covering the tent, there was a large amount of fuel provided. When the fire had erupted, although it may have started very small, it didn’t take long for it to spread over such a large area that the whole audience could see it. The fire needed to be immediately taken out or smothered but it wasn’t possible with water and the proper equipment needed to do so was unavailable to the circus. Thanks to this fire, many states passed fire prevention laws that would regulate way circus tents were to be constructed in the future. Now, after 60 years, there is a monument for the victims that is located at the site of the fire.
