Introduction A sentenceline is used to show when events eat up happened in history. With the bragging(a) Bang theory, people believe that the universe was formed 15 billion long cartridge holder ago when a cosmic enlargement hurled matter in all directions. The Earth is a unripened planet and humans ar the youngest creatures on it. In this lab, we allow put together a history timeline that maps reveal liveness on Earth beginning with the Big Bang 15 billion years ago to the dawn of humans and otherwise animals.
Hypothesis In doing this lab, I favor the impression of gradualism and I believe that is the way that life is started and ultimately improved. So, I command that there is less life some the time approximate to the Big Bang than there is in the time ambient to the map day because life gets started from few things and whence blossoms into more things. As we get surrounding(prenominal) to today, there will be more plants and animals and other forms of life.
Materials and Methods The materials needed to perform this lab are a meter stick, three inch wide m oney register tape, a dark marker, 38 cut pop drawings of life up to 15 billion years ago, crayons, and glue. monetary standard out 15.5 meters of cash register tape and lay it out flat along the floor. touchstone 25 centimeters from one abate of the tape and mark that Present Day with the dark marker. Measure every 10 centimeters, which indicates 100 million years, and label it with a line. Do this until you r for each one the 5 meter mark; then change the markers to every 50 centimeters until you reach 15 billion years ago. Cut out and color the drawings and paste them on the correct accompanying date on the timeline. The last 1.5 meters of the timeline, nearing present day, gets kind of crowded, so just pasting a corner of each picture will suffice.
Results The results of this lab are very concise. on that point was plenty of life toward the end of the timeline; towards present day. There were around ten pictures clumped together between 200 million years ago (genus Mya) and today. At the Big Bang, 15,000 mya, there was only one picture, which was the Big Bang, and the next picture after it wasnt until 10,000 mya which was nucleosynthesis. Pictures were randomly scattered after that and nearing present they started to get closer together.
Discussion Doing this history timeline was, maybe, the most tedious, disturbing, annoying thing I have ever done.
First, the line itself is so long that it is leaden to lug around with out it ripping, 15.5 meters is a long put up of register tape. Second, trying to measure on the ground was non fun and there was much room for measuring errors. Third, we messed up three times on labeling the dates. We couldnt get the dates to run across up with present day and the big bang. Every time we thought we were doing it right we would jump like 700 million years, so then we would have to go back and fix it again. We had 3 different colored dated numbers by the time we were done. But, it just goes to show you that research on this type of parry is not easy and will never be easy. You have to be oh so careful that you date everything as on the dot as possible with little opportunity for error. I infer if this lab was done again, it should all be done in one day and by more grown-up people. Now I am not saying that we are immature, but this was such(prenominal) a pain-staking process, that we just kind of got bored and unconcerned approximately the outcome of the lab.
