hye guys, we meet again after mid-sem break,,

it such a great holidays for me, being home is the best moments after all,,hehee

okay we don't have class on Monday, we do replaced it last time.

we only have class on Thursday and Friday,,

on Wednesday night, we do some revision for topic atmospheric habitat 

before entering class on the next day. Group 7 who did flip-classroom on this topic

have done a really great presentation for us. they provide video via youtube

by using powertoon tools. that was really great, it simple yet we do understand each 

point that the want to delivered. they provide a mind map and some quizzes,

seriously they deserve a big applause for their great efforts. on Thursday we do some

revision regarding this topic with Dr wan

 this is video on atmospheric habitat prepared by group 7

                                                                          the quizzes 

                                                                       the mindmap

                       

then on Friday, we proceed with another topic which is human microbes

some goes with topic, we do studied and revised on this topic before entering the next class

Group Siva did great jobs in their presentation, they include everything, video on youtube, 

mind map in popplet, then some online quizzes. They also provide AR on this 

human microbiome topic. it really helpful for better understanding.

                                                                  video on you tube

AR on human microbiome topic

click here to see the mindmap

click here to answer the quizzes

we submit the quizzes in LMS

Then last but not least, about our thinglink.

i do love this activity, because it not required too much time to do it.

we can freely choose any habitat or place that we find out interesting

and i choose OUR HOME SINKS.. WHY??

 ya, it rare but sink is one of the most important part in our home,

we do clean and wash our hand regularly in sink, 

so i love to share what is actually present in those sink

do visit my thinglink site to find put more,

that all for this week..thank you

                               

                                         microbes that might present in our home sinks

9th April 2015 week 7..Thursday

oyeahhh tomorrow is the last class before midsem break,,
so excited,,hehehe,,
we really have this whole week,maybe the spirit of being home is there,hahaha

okew,,orait,,what we did on last monday??
we proceed with lecture of soil.. doctor give a lot explanation regarding this topic
what i found interesting about this topic is that,it actually related with all the topics that we have learned in class before. however in this lecturer, they more specific for soil habitat and interaction between microbe that inhabit this area.

so proceed with today lecture (Thursday).
today we learned about hydrosphere topic which is my group presentation SCL
we provide a crossword before entering the class
quizlet, animation video and also thinklink note.
we include everything and im proud with all my group member
and what im proud the most, most of us did some revision before entering the class
mission completed..hehe

actually on tuesday, we shoot our POBL in Malacca and PD
IT WAS REALLY OSEMMMM,, i can wait to edit all the videos


10th April 2015.. Friday
we have replacement class this morning,
we proceed with hydrosphere topic
doctor wan prepare 3 question for us
it was good actually, we can test our knowledge for this topic

If you dropped a piece of fruit in your kitchen sink while rinsing it, would you think twice about popping it in your mouth? What if you dropped it in the toilet?If you were to ask someone what object in the bathroom is the most contaminated with bacteria and mould, the answer you would receive is probably “the toilet seat”, however a recent study, undertaken by BioCote, shows that bacteria don’t always thrive in the places we would expect.

Dirty Places: The Kitchen Sink

Although the mere thought of retrieving anything from your toilet bowl may be enough to make you sick, your toilet may be cleaner than your kitchen sink, says Eileen Abruzzo, director of infection control at Long Island College Hospital of Brooklyn, New York. Food particles from plates left to soak or rinsed from dishes on their way to the dishwasher can serve as a breeding ground for illness-causing bacteria, including E. coli and salmonella. They can get on your hands or spread to foods.

Although most people take steps to disinfect their toilet bowls, few give their kitchen sink the same consideration, Abruzzo tells WebMD. “They rinse their sinks with water and assume they are clean -- but they’re not.”

lets find out microbes in each part of our toilet

CLEAN YOUR BATHROOM SINK, BECAUSE IT’S MORE CONTAMINATED THAN THE TOILET

Our microbiology experts took multiple samples from objects and surfaces in a public disabled toilet and tested them for levels of bacteria and mould.

Most people would assume that the toilet seat would be right at the top of the list for high levels of contamination but the level of bacteria found on it was equal to that found on the hand rail and the tap. Topping the list was the sink itself which showed more than 50,000 Colony Forming Units (CFUs).

Dr Richard Hastings, technical director says ‘in many cases germs are spread via touch so we can see that objects touched after people have used the toilet, but before they have washed their hands can be just as contaminated.’

The other interesting results were the levels of bacteria found on the less obvious objects and surfaces such as the floor, the wall and the underneath of the toilet. Dr Hastings explains ‘this is probably because people only tend to clean the areas they can see, and the areas where they expect the bugs to grow. Unfortunately bacteria and mould can be found everywhere and they will just keep multiplying. We know most rooms are full of germs and although they may not necessarily be harmful, the higher the count, the greater the risk of illness.’

The only object in the bathroom on which no traces of bacteria or mould were found was the soap dispenser incorporating BioCote antimicrobial technology.

“There’s more E. coli in a kitchen sink than in a toilet after you flush it. The sink is a great place for E. coli to live and grow since it’s wet and moist. Bacteria feed on the food that people put down the drain and what’s left on dishes in the sink. That’s probably why dogs drink out of the toilet—because there’s less E. coli in it,” says Dr. Germ.
DR. GERM’S ADVICE: “Clean the sink basin with a disinfectant product made for the kitchen. Vinegar and lemon juice can clean some bacteria, but they can’t clean really bad pathogens, so the Environmental Protection Agency doesn’t recommend using them as an alternative.”

SINKS OF MICROBES??

Even if you clean the kitchen sink regularly with soap and water, the dampness, warmth and darkness of the sink drain makes this fixture the most contaminated part of the average home, according to microbiologist Charles Gerba of the University of Arizona. Ordinary soap and water won't kill dangerous pathogens, and cleaning with old sponges spreads the bacteria to whatever surfaces the sponge touches, including faucet handles and counter tops.

Salmonella

• Salmonella, one of the major causes of food poisoning, often enters the kitchen on contaminated meat and poultry. From 31 to 41 percent of the chicken used in an English sanitation study in 2001 tested positive for salmonella, according to an article by Beth Layton in the Saint Martin's University Biology Journal. Poor sanitation practices easily spread the bacteria to fixtures, sinks and sink drains, where the salmonella bacteria multiplies.

Campylobacter

• Campylobacter -- found in dairy, meat and poultry products -- causes diarrhea and could kill young children, the elderly, or those weakened by chronic disease. Dirty sink drains provide good growing conditions for this common pathogen and common cleaning procedures could spread the bacteria rather than kill it. The best treatment for campylobacter and other pathogens involves frequent washing of fixtures and surfaces with a solution of 3 tbsp. chlorine bleach mixed in 1 quart of water, says Susan Ferraro of the New York Daily News.

E-coli

• Bathroom sinks host more E-coli and other fecal bacteria than the toilet seats, according to a University of Arizona study. Not all strains of E-coli cause serious illness, but some strains could cause severe or even fatal illness. The study showed that even though women's restrooms appear cleaner than men's restrooms, bathroom sinks in the women's facilities contained twice the bacterial count.

Staphylococcus Aureus

• Staphylococcus Aureus causes skin infections and could cause more serious problems such as blood poisoning. Methycillin-Resistant Staphylococcus Aureus or MRSA showed up on sinks, countertops and hand towels in a test study funded by HSPH-NIOSH Education and Research Center. Five families with pets and children young enough to wear diapers participated in the study, which the American Public Health Association says also revealed other pathogens including streptococci, enterococci and pseudomonas.

5th April 2015, Sunday, week 6th

hello people,,so we met again this week..
it was the end of week 6th means that we are done with our 1st test dilemma too,,hehehe
i do reward myself by go watching Fast and Furious 7..seriously it was really fascinating.
i also sleep for 13 hours straight on the next day. it was a tough semester after all..hahaha
for almost everyday since the 1st week, we just get 4 hours sleep per day..
all the assignments and the lab reports. what the hectic life kn,hahaha

lets make it simple n short. this week we have lectures on two topic which is
MICROBIAL INTERACTION and also the SOIL topic.

for microbial interaction topic, we do have to search for any related articles or videos regarding any interaction that we find interesting.we do upload it in the padlet..this activity is quite challenging actually, because we need to any find related article in short time and for student like me who does not have smartphone, it really tough to online except i have to bring my own laptop for every eco class,thank to my friend nur aqilah, she really nice for landing her phone to me.. later or soon i need to buy my own smartphone..

then we proceed our 2nd topic on the soil, This topic is actually part of SCL project which is flipclassroom, This topic was handle by group 4. They have prepared a nice and complete mind map for the whole classroom. Dr also give brief explanation about this topic. We also leave a comment for this presentation. I do love this activity because student feel free to share new tools that they find interesting.

click here to follow the full lesson.

This is the full mind map for topic soil

28th March
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.
