Fireworks are a class of explosive pyrotechnic devices used for aesthetic, cultural, and religious purposes. The most common use of a firework is as part of a fireworks display. A fireworks event (also called a fireworks show or pyrotechnics) is a display of the effects produced by firework devices. Fireworks competitions are also regularly held at a number of places. Fireworks take many forms to produce the four primary effects: noise, light, smoke, and floating materials (confetti, for example). They may be designed to burn with flames and sparks of many colors, typically red, orange, yellow, green, blue, purple, and silver. Displays are common throughout the world and are the focal point of many cultural and religious celebrations. The earliest documentation of fireworks dates back to 7th-century China, where they were invented. The fireworks were used to accompany many festivities. The use of fireworks is a part of the culture of China and had its origin there; eventually it spread to other cultures and societies. The art and science of firework-making has developed into an independent profession. In China, pyrotechnicians were respected for their knowledge of complex techniques in mounting fireworks displays.

During the Song Dynasty (960–1279), many of the common people could purchase various kinds of fireworks from market vendors, and grand displays of fireworks were also known to be held. In 1110, a large fireworks display was included in a martial demonstration held to entertain Emperor Huizong of Song (r. 1100–1125) and his court. A record from 1264 states that a rocket-propelled firework went off near the Empress Dowager Gong Sheng and startled her during a feast held in her honor by her son Emperor Lizong of Song (r. 1224–1264).

Each state in america has a different seal, or symbol, that represents the traditional culture of that state. the state seal of georgia is rich in meaning, history, and patriotism. when was the seal adopted? 2georgia’s state constitution established the state seal in 1798. however, as georgia’s political circumstances changed, so too did the state’s seal. between 1863 and 1865, georgia used a different state seal to represent its separation from the rest of the country during the civil war. then, from 1868 to1871, georgia’s secretary of state nathan c. barnett hid the original seal when the capital was occupied by the north’s victorious enemy forces. he readopted the original seal in 1872. 4georgia’s state seal remained unchanged for 42 years. then, a law was passed that required the state to alter the date on the seal. the year 1799 had originally appeared on the seal to represent the year that the seal was officially adopted. the new law changed the date on the seal to 1776, the year that america’s founding fathers signed the declaration of independence. what does the seal look like? 5just as coins each have a “heads” side and a “tails” side, state seals also each have a front and a back. the front of the seal shows three tall columns, or pillars. perched atop these pillars is an arch that displays the word “constitution.” the two end pillars are each adorned with a ribbon-like banner that reads “wisdom” and “moderation.” a third banner, reading “justice,” hangs in front of the middle pillar. when read together, the banners make up the official state motto of georgia: “wisdom, justice, and moderation.” the seal also exhibits a picture of a soldier holding a sword. the words “state of georgia” appear along the top. the year 1776 is printed at the bottom. 6the back of the seal portrays a rural shoreline scene featuring a large ship and small boat. also included in the picture are bundles of tobacco plants and cotton and a farmer working in a field. across the top of the seal are the words “agriculture and commerce.” the bottom of the seal is also marked with the year 1776. what do the symbols on the seal represent? 7each item on the seal is symbolic of georgia’s history and the history of america as a united country. the pillars on the front stand for the three branches of government—legislative, executive, and judicial—and how they all work together to support the country and its constitution. the man holding the sword represents soldiers who defend the country and its laws. 8the boats on the back of the seal symbolize the agricultural commerce of georgia. similarly, the farmer and crop bundles represent georgia’s dependence on agriculture for survival. during the mid to late 1800s, over 700,000 cotton bales were produced each year. cotton is still a “king” crop in georgia. the state currently produces almost three million bales per year. this is only one reason why the state is an important asset to its country. read the passage on the left to answer the following questions: 13) the author's main purpose in writing this article is a) to inform. b) to create. c) to persuade. d) to entertain. 14) in paragraph eight, the word asset means a) benefit. b) debt. c) element. d) expense. 15) in paragraph six, the word portrays means a) condescends. b) deceives. c) honors. d) reveals.
