REFLECTIVE JOURNAL WEEK 5

This week is super packed for us. the week that fulled of exam.
So, this week i have learned about microbial interaction.

there is a video that i want to share with you. it is about nitrogen fixation..

there is one thing that really impressed me which is the hydrothermal vent.

A hydrothermal vent is a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots. Hydrothermal vents exist because the earth is both geologically active and has large amounts of water on its surface and within its crust. Common land types include hot springs, fumaroles and geysers

Thats all for this week .....:)

REFLECTIVE JOURNAL WEEK 4

hello and we meet again!!!
So what had happened in week 4.
Basically, this week we have learned about the energy and carbon source of microrganism. So I have an easiest method on how to remember it. This is my formula:

ENERGY+ELECTRON + CARBON
example : PHOTO- LITHO AUTO- TROPH

 

This week also we have learned the topic about 'Distribution of Microorganisms'. in this topic, one must know the factors  affecting the microbial distribution. 

The physical factors that affecting the distribution of microorganism are:

•  Solutes and Water Activity 
• Temperature 
• Pressure 
• Radiation

Tthe chemical factors that affecting the distribution of microorganism are:

•  pH
• Oxygen Concentration
• Water
• Carbon
• Nitrogen, Phosphorus and Sulfur
• Special Growth Factor
• Trace Elements

In this chapter also one must able  to distinguish the microbes according to the categories.

 

Besides, one must know type of exteremophiles:

In this week, Dr Wan gave ua an activity to be done. it called a crossword game.

This week also I did my own exploring about barophiles. barophiles is the microbes that can live in deep sea. it can withstand pressure under the deep sea.

REFLECTIVE JOURNAL WEEK 3

REFLECTIVE JOURNAL WEEK 3

DATE : 13^TH MARCH 2015

NOTE:

In this topic which is the ‘Microbial Groups’ has several objectives to be achieved. Firstly, we need to identify the range of microorganisms. Then, we need to list down the microbial groups. lastly, we need to differentiate the ecological aspects of the microbial group.

Basically, there are 3 major forms of life which are eucaryote, prokaryote (Bacteria) and viruses.

Eucaryotes :

- fungus

- slime/water molds

- algae

- protozoa

The activity that I had done before the class start was I made a simple note about this topic. Besides, me and my group create a beautiful mind map by using the popplet. It was the first time I did the mind map by using the popplet. It's really a good activity for me because it challenged as I had to make the mind map based on my understanding.

Okayyyyyyyyyyyyy!!!!!!!!!!!!!!!!!!!!! This is the best part. We did a very fun activity called an online quiz by using Kahoot. Trust me, it is the best activity. And I think that it is a good tool for revision.

And dont forget to mention, I did a terminology based on this topic (50 terms all of it). besides, I did a simple test on the Quizlet. hahha.. it's kinda hard for me, but it was a good activity as  it challenged me whether I have an understanding about this topic or not. 

And from this week lecture I thing that hits me the most is about critical thinking. As a microbiology student critical thinking is a thing that one should develop.

Oh YA, there is a fun fact about what I learnt today, which was about watermelon snow.

There is an interesting article i read in science daily.the title of the article is
 Earth microbes may contaminate the search for life on Mars. 

It is about a bacteria common to spacecraft may be able to survive the harsh environment of Mars long enough to inadvertently contaminate Mars with terrestrial life
