"The Cave Of Altamira" Constructed Response

 Question : The text states that the paintings of Altamira could be 13,000-34,000 years old. How did scientists estimate the age of these paintings? Use evidence from the text to support your answer.

Answer : Scientists uncovered the estimate age for the cave paintings (13,000-34,000 years old) by using 2 processes - carbon dating and thorium-uranium dating. According to the text, scientists used the carbon dating method on the black charcoal outline of the animals. Scientists were then able to run tests on the charcoal and receive a time period from when the paintings were made. The text states that the thorium-uranium dating method was to "analyze the mineral layers that formed over the cave painting(s)". Similar to carbon dating, thorium-uranium dating is when a sample of the minerals are tested for their time period. Both results came in as around 15,00-25,00 years ago, making them some of the oldest high-quality cave paintings found.

I did a interesting research about Michelle Kwan. Michelle Kwan was born 1980 in Torrance, California. Her ethic is Chinese and her parents were from Hong Kong. Michelle Kwan started skating at the age of 5 and went to Ice Castle Training Center in Lake Arrowhead in California. She was 18 years old when she went to the Olympics games. Michelle Kwan liked to skate a lot. I think Michelle Kwan has good performance because she is calm and relaxed.

Chinese New Year

I am going to write about Chinese New Year because my parents come from China and Chinese new year is February 16th. Here are some facts I learned about Chinese New Year. Chinese New Year is also called Lunar New Year. Chinese New Year was created to welcome spring but Chinese New Year does not happen on the same day every year because not all the time the groundhog sees his shadow. There are 12 symbols for the Chinese zodiac. The 12 symbols are Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, rooster, Dog and Pig. The year of 2018 is the year of the Dog. I was born in 2010 and I am a Tiger and my sister was born in 2014 and she is a Horse. Chinese New Year is very important because we welcome a new symbol. A Chinese New Year tradition is putting out fireworks and putting up lanterns. Chinese New Year lasts for about 15 days. This is what me and my family do on Chinese New Year this year. We went to Chinatown and we got toys and we got clothes. The clothes I got was
