- The topic I would like to know more about is the backstory of Mexico sinking. 2. K-KNOW: I know that one of the reasons it’s sinking is because they get their water resource from below the ground. I know it also has to deal with the aztec. The sinking has caused buildings to tilt and some have broken from the sides. I know that one building has not been affected. 3. W- Want: I want to know what the aztec had to do with the sinking (more in depth information). I also want to know if there’s other factors that caused this sinking. 4.L-Learned: I learned that it’s sinking because of the result of a geological phenomenon called subsidence. Researches think parts of the city could drop by as much as 65 feet and spots just outside the city could sink 100 feet. I learned that other places are sinking as well such as Indonesia. I learned that there is no way to fix the issue. +STILL WANT TO KNOW: Some questions I still have are what did the aztec have to do with the sinking. The articles I read did not go into depth about that and that’s what I’m curious about. I also still want to know more information on why the sinking is unfixable.

Topic: Immigration
Know: All I know really is that Immigration is currently a huge problem in the US and that many immigrants are suffering from the laws that the US have placed currently.
Want: I want to know why America has these immigration laws in the first place, I want to know about the history of immigration in America. I want to more about the issues that Immigrants face and to see if anything could be done.
Learn: Some of the issues that immigrants faced are proverty, education, employement. The first type of immigrants that came to the US were the pilgrams back at the 1600s however the first major big wave of immigrants that the US faced was during the late 1880s to 1920s.
Still want to know questions-
Are Immigrants the main cause of how America is today?
Should Immigrants be treated the same as a normal US citizen?

- The reproductive cycles of certain lizards.
- Under certain conditions, external or internal, certain species of lizards or perhaps all of them have the ability for the females of said species to reproduce without the need of a male to fertilize their eggs. This strange thing that female lizards can do seems to be a response to certain conditions found within their environments. If there happens to be a lack of males to mate and fertilize eggs with, as a survival strategy to ensure the safety of the population of their species, female lizards will still lay eggs that hatch into fully formed and healthy newborn lizards. These newborns are direct clones of the lizard that laid the eggs and thus are all females.
- I want to what species of reptile or lizard have this ability to procreate without sexual reproduction, what are the conditions necessary for this event to occur, why does it happen, is it a safe and effective means of prolonging the survival of a species, how did this ability come about to begin with and when did lizards and other organisms gain the ability to reproduce asexually?
- So apparently, it has been discovered thus far that about 70 species of vertebrates have this ability to reproduce asexually from a process called parthenogenesis, and it isn’t limited to only lizards. The offspring are usually direct clones of their mother, but the organisms do have a way of producing genetically diverse offspring without the aid of a male. During the cellular division process called meiosis, the daughter cells acquire twice the usual amount of chromosomes and are able to get a full set of chromosomes from two sets of pairs derived from the mother. This allows the offspring to be fully genetically diverse from the mother it was born form and thus protect the population’s genetic diversity.
- I still want to know how these few vertebrates gained the ability to reproduce asexually, when did this occur, and what are the trigger conditions for this event to take place. Why is this ability to asexually reproduce present in several species of vertebrates that don’t have any relation to each other, and why do so few in general have the capacity to do this?
