Guppies!

In science class, we are taking care of mini ecosystems. And with these ecosystems comes knowing about the different animals we are taking care of. Right now we are doing an aquatic ecosystem, and today we just added guppies to our tanks! Today I'm going to talk about the different needs for the guppies, how my table group will help meet the guppies' needs, what type of interactions I think will happen with the guppies and mini ecosystem, and how many more guppies we will be able to put in our tank and keep it alive.

First off with the guppies' needs. For tank water, it is recommended that you put 1 gallon of tank water per guppy. If you stick to the 1 to 1 ratio, this will provide enough space for the guppies to swim, keep the water parameters under control, and not make the tank too crowded. (http://guppyfishcare.com/guppy-tank-size-how-big-tank/) The temperature of the tank should be about 23 degrees celsius to 27 degrees celsius and the pH of the tank should also be about 5.5 to 8.5. If we have higher temperature levels, it will cause the guppies to grow faster and die faster. While if we have lower temperatures, it will cause the guppies to grow slower and live longer. But if we have higher temperatures, it can cause cloudiness in the tank because of the elevated bacteria growth.
(http://www.guppies.com/) My group will meet the guppies' needs by always checking the water pH and temperature, then logging it in. Also if we do see cloudiness in our tank, we will add oxygen into the tank to clear that away.

In our tank we have to guppies. One female and one male. Some interactions that I think will happen, is that the male and female will start to breed a lot since a female can breed very fast and can store her sperm for later on when it's needed. (http://pets.thenest.com/guppies-pregnant-3838.html) And also we thought that the female guppy was pregnant the last time we checked. From my observations today though, there wasn't much interaction in the ecosystem and there wasn't any interaction with the other populations inside the ecosystem, except that we thought that the guppies ate the tubifex worms. If we want to add more guppies and still keep them alive, it is best to add about three more since we have a five gallon tank and we already have two guppies. This will make things less crowded.

Water Bill

The chart above shows my family's monthly water consumption. In August it was 72.8 cubic meters, in september it was 60.5 cubic meters, in October it was 64.9 cubic meters, in November it was 63.7 cubic meters, in December it was 25.8, and for January it was 47.7. The average is 55.9 cubic meters per month. The target was the average reduced to 20% less of our water consumption and the amount we would want to use instead of using an a lot more wasteful amount. Our target was 44.72 cubic meters per month.

Significancy of Schindler's List: News Package

News Package Element/ Time Reference Script Introduction The Holocaust is one of the most famous genocides known by many around the world. There has always been speculation whether the movie, Schindler’s List, and its goriness was ever appropriate for students, especially for those who couldn’t handle the gruesome content in the movie. But one filmmaker, Steven Spielberg, made a monumental movement. He changed the lives of many with just one movie. He brought perspectives on prejudice and bullying to light in the phenomenal movie, Schindler’s List . Soundbite 1: Matthew Elms, 8th grade C-side social studies teacher (Elms, 5:43) “I have a hard time imagining an intelligent person sitting down and watching that movie and not being changed. And being the same person afterwards that they were before.” Bridge When asked on how the movie could change people’s perspectives on the world and prejudice, Matthew Elms, an eighth grade social studies teacher at SAS, had a s...

Target

Airplanes flying low, smoke and fire everywhere, and destruction of the twins falling down. That was nine-eleven. It was the tragedy that shook the entire world and the time where many lives were lost trying to save the innocent.Tears fled from people’s eyes like a stream and hearts were slowly tearing apart as loved ones were getting torn apart from them. Grief and condolences were sent to the US and its people. And during that very sad time, Muslims were discriminated because about one percent of their population were the ones who attacked. Persecuted for doing something they didn’t do, something they didn’t have control of. Even being called horrible names like “terrorist”.  Going to an American school and being the only Muslim in my grade, I felt like a social casualty. A lost puppy in a thunderstorm. We used to talk about this event in class every year and my teacher would talk about the culprits that were the Muslim terrorists. And I would see the few peers who woul...
