Mind Map Time!

From my previous post, I mentioned about mind map but I did not finish mine (individually) yet, so yesssss I am so excited to show it here :D


For the first time in my life, I feel like I am able to understand what I read based on my mind map made by myself. Therefore, I honestly think that this application introduced by Dr. Wan is so useful! And I'm surely going to use it for next topics too!

However, what we were discussing on that day was INTRODUCTION TO PROKARYOTES which only covered the external parts. The definition of prokaryotes is a group of organisms that lack a cell nucleus or any other membrane-bound organelles.
We learn about the size-shape relationship, in example, the lower the size, the storage will become smaller but it will increase the movement.

The structure consists of flagella (monotrichous, lophotrichous, amphitrichous, pertrichous), fimbriae and pili, glycocalyx (capsules, slime layer) and axial filaments. Cell wall is divided into two -  gram positive and gram negative. 

About half an hour before our class end, Dr Wan asked us to make a mind map at the white board and everyone must contribute in it.
So here is the result :)

That's all. The class was fun by the way :)

Microscopic World

Basically we are still in our second topic which is MICROSCOPY.
We proceed to staining. There are smears-step involved, which are preparing smears, fixation and staining.

Under fixation, there are : heat fixing
                                               : chemical fixing
Importance of fixation is to preserves internal & external structures and fixed them in position.
3 types of staining : Simple staining
                                    : Differential staining
                                  : Special staining
 Dyes or stains give colour so it will be more visible under microscope and easier to differentiate. Differential staining includes gram staining and acid-fast staining.
Difference between simple staining and gram staining is simple staining uses single staining while gram staining uses 2 stains, crystal violet & safranin.
Procedure involved in gram staining are fixation (crysal violet), iodine treatment, decolourization, and counter stain (safranin).
 Gram positive(usually rod-shape) maintain in purple colour as it wont decolourized. Gram negative (usually coccus) - pink.
Acid fast-staining is used instead of other staining because it involves fastidious bacteria.
Eg : Mycobacterium
Special staining will only stain specific structures which are endospore, flagella and negative staining. 
That's all for this topic. and we did proceed to third topic, PROKARYOTES. 
 We were asked to make a mind map using application such as examtime (I only remember this as my group used this for our mind map)



This is only for the external, and we are going to make mind map on the internal parts individually.
Never knew about all these applications before huhuhu. If Dr Wan did not told us about it, surely I will still use microsoft words to make a mind map haha.

That's all :)

New Day New Topic

Well, as usual, a surprise from Dr. Wan again hehehe. Dr wan changed a little bit regarding our project. The new name is 'Thank A Microbe'. still a group work project, however, 'Adapt A Microbe' project now is an individual project! 

Dr Wan showed us one of e-journal written by one of our students in our class. In he/she e-journal's, he/she include (and I searched for the images)
  • Biggest bacteria : Thiomargarita namibiensis
 
  • Bacillus anthracis : causes antharax
 
  • Desulfovibrio vulgaris : sulfur eating bacteria
 
  • Riftia pachyptila : live in hydrothermal vents
 


And we started a new topic. 'Brief History of Microbiology'. 
The first microbiologist was Antonie van Leeuwenhoek who invented the first microscope. Robert Hooke then proposed a theory, "All living things are composed of cells". Antonie van Leeuwenhoek proposed spontaneous generation. John Needham gave an evidence to spontaneous generation, but Lazzaro Spallanzani dissapproved Needham's theory and the issue remain unsolved. Eventually, Rudolf Virchow proposed, "Living cells can arise only from preexisting living cells" It is then resolved by Louis Pasteur with Pasteur's experiment.
We also learn about Koch's Postulates. From what I understand, the steps are:
  1. Inject pathogen from disease
  2. Isolate the pathogen
  3. Culture in a medium to obtain pure culture
  4. Inject to a healthy person
  5. If same symptoms appear, it proves that particular pathogen cause the particular disease
After that, we started our second topic MICROSCOPIC. I get to know that there are light-field microscope, dark-field microscope, fluorescence and electron microscope( SEM &TEM)
Before we end our class, Dr Wan did a short quiz. The class was quiet tiring as it was 3 hours lecture and yes we were a bit surprised with the quiz and the changing of formats regarding our project. But still, the class was fun and I enjoyed it.

New Big Project

It was our third class when Dr. Wan actually surprised us with ONE BIG PROJECT!!!!! Our class have to make an augmented reality video which we are going to make a poster and a video. What makes it interesting is, we will use our smartphone to scan any images on our poster, and a video will be played on our smartphone!

Dr, Wan showed us a n example of the video 

This project is actually for a competition. The best poster and video will be selected and will be sent to join the competition before 31st of October.


After the briefing about the project was done, we continued our lesson about introduction to microbiology. For some memories refreshment, Dr Wan asked us regarding the topic at the end of class.
And we walked out from class with our mind kept thinking what we are going to do with the project. Hmmmmm

Assignmentsssssssss

We started our class with the presentation of our assignments (videos).



Then, we began to learn a little bit about microbiology. Dr. Wan explained to us the first topic, 'INTRODUCTION TO MICROBIOLOGY'
When it was about time, Dr Wan asked us to list down all words that we heard during the whole period of lesson.

That's all :)

First day of microbiology class

On 9th of September 2014, my classmates (coursemates) and I entered microbiology class. We got to know our awesome yet sporting lecturer, Dr. Wan Zuhainis. Dr. Wan gave a brief introduction to our class. 
Next, she asked us to answer 2 questions on padlet. The first one is, What do you know about microbiology?




 Second question was, what do you want to know about microbiology?



Before class dismissed, Dr. Wan assigned us an assignment which we have to make a video telling about ourselves.
