I read Pickle Impossible for a Global Literature Circle book. I wanted a book that looked like it would be a great book to read. I wanted a book about mystery and the title fit my reasons to read it. This book is action-packed and leaves suspense at the end of each chapter. It was a really good book, with lots of good humor. I liked the setup of the story, having Pierre and Aurore having to solve all the little problems to get to the major part in the story - the contest! The thing I didn't like about it was that in the beginning there wasn't much description about the setting. It wasn't a major problem but I would've enjoyed it more if the author had added more description. Overall, this was a great book and I encourage people to read this book!
Today we got to do an activity for our Digestive System paper. We made a web to use when we are writing our paper. This web explains the basics of the Digestive System.
Question #1a: How did the gelatin change in cup 1? Did it's appearance change? Did it's ability to pass through the filter change?
The gelatin's appearance DID change. About a minute after we started the gelatin with the enzyme powder was already seeping through the coffee filter. The enzyme powder was turning the gelatin to a liquidy substance and it was going through the filter.
Question #1b: Did the enzyme powder cause the change in cup 1? How can you be sure?
The enzyme powder was breaking down the gelatin in cup 1 because the gelatin was becoming yellowish liquid. In cup 2 there was no change with the gelatin.
Question #2a: In which cup did the gelatin;s nutrients reach the "bloodstream"?
The cup with the enzyme allowed the gelatin's nutrients to reach the bloodstream because the enzyme dissolved the gelatin and the nutrients from the gelatin reached the bloodstream.
Question #2b: What does your model suggest must happen to the food before it can enter the bloodstream?
The food must be broken down into tiny parts so the nutrients and food can pass through the capillaries and go into the bloodstream.
Question #3: Based on your model, would food be of any use to yur body if you couldn't digest it?
Food would in fact be practically useless to our bodies if we couldn't digest it because we wouldn't be able to supply the nutrients needed to the cells because the food couldn't be digested and no nutrients would be extracted.
The afternoon session at the field museum we learned about meteorites. We learned that there are 3 types of meteorites: Iron meteorites, stone meteorites, and meteorites that contain both. Also, meteorites have come very close to the earth's atmosphere and if a meteor came into Earth's atmosphere and it was big enough it could could cause a destruction like the end of the dinosaurs. Of course that is highly unlikely because scientists have cool inventions that allow them to detect meteors and alert people. It was fun and worth taking a day of of school because we got to learn about meteorites and Jim told us many things I didn't know about meteorites. I think the most interesting thing I learned was that a shooting star is really just a meteor that is going so fast it starts to burn up and when it starts to burn up the heat and pressure creates the indents we see on meteorites. I think we should spend money on researching meteorites because we could learn how and if the
On January 30th we got to go to the field museum. We got to learn about meteorites and the theory of how the dinosaurs died. In the morning session we learned about the theory of how dinosaurs died. Dennis, our docent, told us how the earth had weather that was always changing and how at first the temperature was too hot for anything to grow. He told us that much of earth was covered in water so the first creatures were marine creatures. There were sharks like the megalodon which were killer predators. We learned that as the islands were formed by volcanoes some marine creatures evolved legs and went on land and became the first amphibians. Over time we learned that as the weather began to slow down in change the creatures were adapting to the change and evolved. Around 200 million years ago the first mammals evolved, but they were not much more than small rodents. Before the primates became humans there was the most famous extinction 65 million years ago. All dinosaurs were wiped out except for a small portion which evolved into the modern day birds. Over time the mammals evolved and became the first primates.
The morning session was worth taking a day off of school because we got to learn such interesting things about the formation and evolution of earth. I think that the most interesting thing that I learned was that there were so many different periods in earth's history like how at one point there was almost no land mass and then islands formed and amphibians walked on land. I think it could be possible for other planets to sustain life because the creatures on that planet wold have to be used to that climate so they could live on that planet
