assalamualaikum..mornng to all.how was your day??

i just woke up this morning n got a message from my lecturer..
" thank you for sharing info on hydrosphere n need your reflection on this week activity"

sharing info on hydrosphere?? why so suddenly?? yesssss.......
i do update a lot of info regarding hydrosphere this week..even though we have not cover this topic yet. this is part of our activities for flippclassroom task.. we are going to share this info with other course mate as the preparation before entering the class.
im going to promote my own blog..oyeaaaahhhhhhh
there are lot more things we did for this task..but i cant show it now..secret??haha

so back to the topic, regarding to my reflective journal for this week..
we dont have class on Monday for this week.
basically, we have only two hours  eco-class this week

we do discuss about our big project for this semester which is POBL
on topic LIFE WITHOUT MICORBES.. the carry mark for this SCL is 20..
yes, it lots bcoz we going to make this really BIGGGGG..
i hope there will be great cooperation from all microbes students
we create all the AJKs for this event..all students have to get involve..

actually im really worried n nervous..
are we going to be okay??is this really okay??
this is though,,really though..
n it is not only about cooperation , it about time consuming.
we need to sacrifice a lot of time that actually we our-self  don't have
i just hope everyone get involve n finish it as soon as possible.
we do have a best team work  n let have faith with them..

then we proceed with our lecture on topic 5
which is MICROBIAL INTERACTION
is all about the interaction..
either mutualism, commensalim, cooperation n lot more
we have not finish this topic yet, n we are going to continue on this Monday
ohh yaa.. we are asked to find some related journal, videos or anything that related to the interaction in microorganism in the class before. they do share alot of infos.

Lentic and Lotic Ecosystems

We all depend on water for our survival. Pennsylvania is home to thousands of kinds of organisms that depend on freshwater ecosystems for their survival, too. The freshwater aquatic biome contains both lentic ecosystems and lotic ecosystems.

Lentic Ecosystems: Standing Water

Some examples of lentic ecosystems are lakes, ponds, swamps, marshes, and vernal pools. Lentic ecosystems take many forms, from small, temporary pools to large lakes. Some lentic ecosystems are fresh water with low salt content, and others have a higher salt content (Example: The Great Salt Lake in Utah). Lentic ecosystems such as lakes can be formed by glaciers, volcanoes, and shifting of tectonic plates, and some are man-made. Some, such as vernal pools, are only temporary during a rainy or wet season. Lentic ecosystems have layers from top to bottom that support different organisms, depending on factors such as the amount of light and temperature. Algae and aquatic plants produce food for other organisms in the ecosystem. Many tiny invertebrates, called zooplankton, live in lentic waters. They feed on algae and plants and provide food for other organisms such as snails and insects like water striders. The kinds of fish and other vertebrates depends on many factors, such as the salt content, amount of light, and depth of the water. There are many species of lentic vertebrates, including salamanders, frogs, alligators, and many kinds of birds.

Lotic Ecosystems: Flowing Water

Examples of lotic ecosystems are rivers, streams, creeks, brooks, and springs. Pennsylvania has about 45,000 miles of flowing water. Lotic ecosystems can have many forms, from a tiny spring to a wide, rushing river. A spring is a place where water flows from underground to above ground. They do have some common characteristics. They always flow in one direction. They often begin in the mountains, formed by snowmelt and rain, and they flow downward over the land. They tend to last hundreds of thousands of years, but some smaller ecosystems such as creeks may dry up each year as the seasons change. The types of organisms that live in lotic ecosystems depend on how fast the water is flowing, the amount of light, and the temperature. Organisms in lotic systems must be adapted to handle the high oxygen content, which is caused by the flowing water. Lotic systems have a low salt content. Animals must be able to prevent excess water from building up in their bodies. Algae and plants provide energy for animals in lotic ecosystems. Many invertebrates, such as insects, snails, and crayfish, depend on the flowing water to bring them oxygen and nutrients. Fish that live in lotic ecosystems must be adapted to survive in flowing water. Many lotic systems connect to each other and form a path to the ocean (example: spring → stream → river → ocean), so some fish species spend part of their lives in freshwater and part in the ocean. Other vertebrates spend part of the time on land and part in the water, such as species of amphibians, reptiles, mammals, and birds. Specific examples include: frogs, salamanders, snakes, turtles, beavers, and river otters.

Zonation of lake based on temperature:

-Epilimnion- warm & rich O2

-thermocline- rapid decrease of temp

-Hypolimnion- low temp, low O2, poor light penetration

Factors affecting growth of microorganisms in ponds and lakes

·       -   Temperature  (0-100⁰C)

·        -    pH

·        - Oxygen ( Limiting factor)

·       - Sunlight Penetration

·        -   Nutrients

Physical and Chemical Features

            Light and temperature are two key physical features of lakes and ponds. Light from the sun is absorbed, scattered, and reflected as it passes through Earth's atmosphere, the water's surface, and the water. The quantity and quality of light reaching the surface of a lake or pond depends on a variety of factors, including time of day, season, latitude, and weather. The quality and quantity of light passing through lake or pond water is affected by properties of the water, including the amount of particulates (such as algae) and the concentration of dissolved compounds. (For example, dissolved organic carbon controls how far ultraviolet wavelengths of light penetrate into the water.)

            Light and wind combine to affect water temperature in lakes and ponds. Most lakes undergo a process called thermal stratification, which creates three distinct zones of water temperature. In summer, the water in the shallowest layer (called the epilimnion) is warm, whereas the water in the deepest layer (called the hypolimnion) is cold. The middle layer, the metalimnion, is a region of rapid temperature change. In winter, the pattern of thermal stratification is reversed such that the epilimnion is colder than the hypolimnion. In many lakes, thermal stratification breaks down each fall and spring when rapidly changing air temperatures and wind cause mixing. However, not all lakes follow this general pattern. Some lakes mix only once a year and others mix continuously.

Habitats and Diversity

            Lakes and ponds are characterized by three main habitats: the pelagic zone, the littoral zone, and the benthic zone. The pelagic zone is the open water area of lakes and ponds. In large lakes, the pelagic zone makes up most of the lake's volume. The littoral zone is the inshore area where light penetrates to the bottom. This zone often contains large, rooted plants called macrophytes. The areas of the lake or pond bottom that are not part of the littoral zone are referred to as the benthic zone. This zone contains fine sediment that is free of plant life because light levels are too low to support plant growth.

               Lakes and ponds typically contain a diversity of organisms that perform different ecological functions. Many of the organisms in lakes and ponds are quite small and can only be seen with a microscope. Plankton are microscopic aquatic organisms, including bacteria, algae, and zooplankton, that have little or no means of locomotion. In addition, there are many larger vertebrate animals that inhabit lakes and ponds, including fish and amphibians. Other organisms that use lakes and ponds for some activities include birds such as ducks, mammals such as beavers, and reptiles such as snakes.

                 Larger lakes can support as many as four or five different trophic levels, or groups of organisms that get energy in the same way. For instance, the major trophic levels in the pelagic zone, or open water areas, are phytoplankton , zooplankton, planktivorous (plankton-eating) fish, and piscivorous (fish-eating) fish. Microbes such as bacteria and protists are also important in lakes and ponds due to their role in decomposition and nutrient recycling. The food web in the pelagic zone is connected to the inshore food web because many mobile organisms from the pelagic zone (especially fish) use the inshore areas for shelter and food.

week 4

I'm nearly forgot to update my blog this week. I guess maybe coz Im too tired with all the lab reports and first test is just around the corner..huhuhu

so basically what have we done this week??on Monday we only have lecture on topic 4, DISTRIBUTION OF MICROORGANISM . It quit rushing day, we need to finish the lectures faster because it going to come out in our first test this Thursday. We do some crossword as assignment and we submit the picture to the edmodo.

crossword on nutrition topic

apart than that, we do quick revision on the topics that going to come out in the first test. This first test carry mark is only 10 but its going to cover all four topics that we have studied. everyone was very nervous and seriously the questions is quit challenging. this is our second time to have Dr Wan as our lecturer. Last time Dr question was like simple one but yesterday most of us got shocked with those kind of question.hihihi.. let bygone, bygone right,,hhehhe

I think that all for this week. Till we meet again, byee

13th March 2015, friday

we have replacement class today. 8-10 am.. Kesimpulannya,,, we make a new record this time, we have 5days straight morning class this week.. hahaha. Sabar jelaa.. hehe

Okew we continue with lectures on Microbial Group. Other than that we need to upload quizlet test that we did on Metabolism and Nutrition topic in the lms and also Blandspace so that everyone can share it.

This is the example of my quizlet test question.

click here to see other quizlet too..

after finish with Microbial Group topic, we proceed with new topic, METABOLISM AND NUTRITION. just a quick review actually. I realized that we have lack of deep thinking.. DEEP THINKING?? i do felt down sometime bcoz of this, yeahh Dr was right, in order to know about a lot of things we need to be more curious.. CURIOSITY?? That word again..huhu.. most of us did score well bcoz we really focus on note and exam but if we were ask about something out from the note,, thennnnnn..hahaaaa we lost...really really lost. macam mana tue??

12th march 2015

Topic 2: MICROBIAL GROUP

huhuhu,,today we supposed to have 4 hours ecology class but due to no empty class, we finish early.
wowww..interesting day..
firstly we try to connect to biotech wifi and it was really tough. everyone hve to accesss internet at the same time,, memang xbole la kan, thnk u for both technician, bro and sister. they spend about two hours just to fix thing out. then finally we all get access,,oyeahhh

KAHOOOTTTTT.. wow,,that really interesting tool. we were ask to do some quizzes online.. DR.... it was really fun and exciting. no pressure at all. At first everyone was like.. what is this??? suddenly TIME OUT..hahahaha..it got timer.. ten to twenty seconds only. it simple but we need to stay focus..

Aaahh i just got too excited till forget to share bout the lecture right,okehh.. so we continue with microbial group lecture. we just go through certain part that hard to understand because basically we already discussed on this topic during first semester. 

Topic 3: NUTRITION AND METABOLISM

yess, one more thing we also do quizlet. we have to find 50 terms that related to NUTRITION AND METABOLISM topic and define it. This time we are allow to refer notes. We save it as share so that other can open and take a look at our terms also.

Do take a look on my terms

im back..it my 3rd weeks of lectures..huhhh..fuuhhh.. it was really tiring. "Uni life" kan.. can't do nothing. lets just face it. :)

TOPIC 2: MICROBIAL GROUP

Before entering ecology class on monday we were ask to read first on microbial group topic and do summarize it in simple way and upload those mind map in lms. However, instead of doing  mind map, most of us did search for video related to the topic in youtube. It much more easier and really fascinating too. They did found a really interesting video and share it with the rest of class members through blendspace. I think it was a good idea to upload those mind map and video bcoz we can share a lot of info and i do upload some note from other friends. seriously they really did a good job. They do include a lot of information. Im really curious about their curiosity okay,,hahaha

           

                                                   

      

As you can see, it my mind map and note.

We do share it in blendspace.

click here to view my classmate mind maps and video

then in the class we were ask to summarized our understanding and memorizing into another mind map but for a group work. This time we use popplet tool. No one can refer to the note, so it quite challenging actually. We divide evenly so that everyone each part of the topic. Once again we upload those mind map group at Blendspace, so we can refer to any other groups mind map too. Sharing is caring kan..

                                                            click here to clear image

See, every group submit their mind map in Blendspace. click here

TOPIC 3: MICROBIAL NUTRITION AND METABOLISM

Like always, we need to prepare first before entering the class on Thursday. The topic that we are going to discuss tomorrow is microbial nutrition and metabolism. I heard that this will come out during our first test. I hope that metabolism part not going to come out this time coz it really  need a lot of reading and memorizing,hehehe.. we might be ask to do quizlet during the class tomorrow. Most of my friends do sleep late tonight. It already near to 1.00 am but they still focus. tomorrow will be individual task and everyone was worried what going to happen tomorrow. And im'ma here update my blog.. cannot digest any note dah,,hahaha..okew night everyone. sleep tight. tomorrow 4 hour class straight okeyy..bubyee

TOPIC ONE:INTRODUCTION TO PRINCIPLE OF ECOLOGY

1'st & 2nd WEEK:

         The first topic of this course is basically bout introduction to ecology, definition of word E.C.O.L.O.G.Y. the principle behind it, all the hierarchy and all factors that effects the distribution of organism in our ecosystem.

         For your information, my lecturer for this class is someone that so energetic and she really expert in all this new technologies, new software and latest learning tools that will make the lecture and class become more interesting and fun.

        The first thing that we have to do in our first class was to find an article that we find might be related to the Principle of microbial ecology. At first everyone were so confuse, seriously because no one is prepare for this, we not even know what ecology is all about. First assignment on the first day of the class but thank God, Dr. gave us a few days to fulfill this task. After upload it in Edmodo we need to read comment on other articles too. Everyone got nervous bcoz they not sure either they gave the right article or not. Me, myself have to read a lot of articles just to find the suitable one. Alhamdulillah after two days of searching I finally get something to share.

           

This is my first article that I found related to my task.

                                CLICK HERE TO VIEW FULL TEXT

My comment regarding to friend article.

          On the following week, we sat in our group to find the most interesting article that had been uploaded and list out the principles to the Padlet. Each group gave short briefing about their article and Dr. gave comment for each group. It was a good exercising actually. This bcoz instead of find and article we learn how to suck out all the important points. Even though we have been expose to a lot of articles before this but we are still having problem to understand certain texts.

  

We choose the article that we find interesting and suck all important points regarding to the principle of ecology.

       Basically, it quite though task for us, but I sure everyone had give their 110% effort. so GOOD JOB GUYS..on the last lecture of this topic, we were ask to summarize the topic by group. Once again we use Padlet. Honestly, I think this is the best part of all of the activities. I don't why but I love to sit together and try to recall back what we have learn for this 2 previous week without even try to look at any notes or try to Google it. It help us to analyse about our understanding and knowledge. I love to do this kind of activity in the next topic too. Tq Dr.

As u can see, this our summarize.

Assalamualaikum, hello gorgeous and what’s up handsome.. J

First of all welcome to my blog. Actually this is my first experience to create my own blog. Usually I just love to scroll and read other blogs about healthy life style, traditional beauty tips and fashion, of course as lady I really take care about my appearance, hehe. However, I’m not going to share about all this beauty stories throughout this blog but I got something that more interesting, more fascinating, more enjoyable. Excited??

         

           It something that we can’t see by naked eye, something that we can’t be far apart, something that always there in our body, our cloth and of course in our environment. Can you imagine what is it? Try to spell this out, M.I.C.R.O.O.R.G.A.N.I.S.M... Yes that right, microorganism or we can just call it microbes. Small organism that cannot be seen by naked eye, we can only observe it under microscope. The people whose study and work in this field, we call them as M.I.C.R.O.B.I.O.L.O.G.I.S.T.. so am I, microbiologist to be. Hehe pray the best for me and my friends okay.

             Before we start into more deep and serious topic let me introduce myself. My name is Shakinah Shakiren, can just call me kina or shak. I’m second year student from UPM, major in microbiology course in Biotechnology Faculty, still got 4 more semester to finish my degree. Huhh. Throughout this blog I’m going to share about my experiences, feelings, thoughts, opinion and feedback taking ecology of microbes class this semester. It like my own diary. I hope you enjoy JJ
