Science Lab


     Today in science lab room 14 learned about plastic. The students first learned about how plastics are in almost everything. Students had five minutes to make a list of everything that they used on a daily basis that contained plastic starting from when they wake up in the morning. Mrs. Martinez then gave an example that showed how plastic can not always be a positive aspect. She said how scientists gathered a group of people with the same blood type and divided them in half. Each group was fed the exact same breakfast, lunch and dinner for seven days. The only difference was that one group was having canned soup for lunch while the other group had homemade soup. At the end of the week, the scientists tested everyone's blood again and found something very shocking. The group that had canned soup for lunch had one thousand plastic particles in their blood. This was because the soup can was lined with plastic and the soup absorbed it. This comes to the conclusion that plastic can helpful but also dangerous at the same time.
