Keeping the Pearls of Wisdom - Preserving the Carrier and Messenger

HotScience │Petrosains

The gist of the session is about preserving the past and learning for the present and future. 

What we learn about the past is not just from artefacts but also knowledge that has been:
a. Acquired from various sources
b. Moulded through research and experiments, and
c. Re-interpreted and manifested through innovations and inventions

During the Islamic Golden Age (mid-8th – mid-13th century), scholars from China, Persia and Central Asia gathered at Baghdad, the center of education and culture.  Institutions of learning, knowledge and research were established and complemented with multi-disciplined and science-based scholars.  What we see today are innovations and inventions that had contributed immensely to mankind then, to us presently and to future generations.

About the Speaker

Mr. Friedrich Farid Zink is the Head of Conservation and Research Centre at the Islamic Arts Museum Malaysia (IAMM).  He earned his Certificate in Conservation as Conservator/Restorer for Cultural Heritage and Collections (equivalent to the MA which was later introduced in Germany) from the University Mainz, Germany. 

He served as an Assistant Professor (Guest Professor) at the Department of History & Pakistan Studies, International Islamic University, Islamabad, Pakistan and was also the Independent Consultant for Conservation/Restoration, Cultural Resource and Heritage Management for projects of the State of Qatar, Ministry of Foreign Affairs, Germany and Department of Antiquities and Museums (DOAM), Pakistan.

Of Magic & Chemistry

Towards the end of year 2013, we are celebrating the wonders of science and this time it's having fun with chemistry! The theme is called 'Of Magic & Chemistry'. In conjunction with this theme, we are also giving out a 2-in-1 colourful periodic table and 2014 table calendar to visitors.             

There are many activities listed for visitors to try. Did you know that forensic scientists study how ink breaks down into separate colours in order to solve crimes? We call this chromatography. You can give it a try at Petrosains!

In the ‘Zesty Candle’ activity at Petrosains, you can make your own homemade candle. You need half an orange with the insides scooped out and some olive oil! Orange skin contains a flammable oil with a compound called limonene. Limonene gives oranges and other citrus fruits their distinctive smell! The Zesty Candle made from the orange skin and olive oil produces a fresh citrus scent but with all flammable items, so great care must be taken. 

Our fun science demonstrations on chemistry stimulates you to discover how ordinary works of science can be such an exciting and unforgettable experience! The picture below shows our science communicator performing a science show about ‘Combustion’. Basically he is explaining the three elements that is needed to ignite and sustain a fire, which are fuel, heat and oxygen. 

Hope this will change the mindset that we can only learn and do chemistry in a lab. In actual fact we are free to discover chemical reactions at home using everyday materials. But kids, make sure you have parental guidance if dealing with fire! Or else..

Petrosains Science Show Competition Final 2013

Petrosains successfully held the grand finals of Petrosains National Science Show Competition for the fifth consecutive year on  23rd and 24th October 2013.  Kompleks Kraf, Jalan Conlay was once again became the official venue for the final competition for both the school category and the open category.

After the initial kick-off in early February this year, we received  a total of  317 entries  from secondary schools all over Malaysia including from boarding schools such as Maktab Rendah Sains Mara. After a stringent selection process by our panel of judges,  60 teams were shortlisted and competed against each other in the six zone level competition held in Johor Bharu, Kuala Lumpur, Kuantan, Kuching, Kota Kinabalu and Sg. Petani. . The winner from each zone then proceeded to the grand finals together with two wildcard teams chosen by the panel of judges to compete in the grand finals.on 2013.

Some science hunting with the participants from Sarawak

As for the open category,  36 entries were received from teams representing public and private higher learning institutions in Malaysia as well as open teams.  . After vetting thoroughly , the panel of judges  selected  19 teams to compete in  the semi final round and with that, the top nine teams emerged to compete in the grand finals.

This competition is an initiative taken by Petrosains, to promote effective and informal learning methods, and popularize the subjects of science amongst secondary school students, This competition also takes things one step further by putting s students on stage and  giving them the opportunity to explain science to others. This indirectly refines and deepens their own understanding of the science concept and  helps in building their confidence and communication skills that will be a huge asset for them in the future. Other than just performing for the final, the finalists of this year’s school category were also given the opportunity to have a direct up-close  session with Dr. Graham Walker, a PhD holder in science show from Australia National University. During the session, Dr. Graham shared valuable information and tips in science show performing.

Polymers From Marine Bacteria?

HotScience│Petrosains

We see and use many types of polymers every day, it’s just that it’s known to us by different names.  The most common polymer is plastics and it comes in many forms – plastic bags, ATM and credit cards, our five ringgit notes and toys.  There’s also fabrics like rayon, nylon, and polyester.  These are synthetic polymers, i.e. they are man-made.

The other type of polymers, known as natural polymers, can be found in nature and within us.  They are also known as natural biopolymers, i.e. polymers produced by living organisms. DNA is a natural polymer found in all living things and it will be very difficult for us to survive without it.  There are also other natural polymers, e.g. cotton, silk, rubber, leather and cotton; that can be modified chemically to produce many of the consumer products we love and can’t do without!

So, what’s a polymer? 

It’s a compound formed from long chains of the same molecule group. These chains repeat over and over, just like paper clips of the same type and colour joined together.  Polymers can be made to be flexible, pliable and stretchy, yet strong and firm by linking the molecule chains in several places.  Depends on what we want.

Now that we know the difference between synthetic and natural polymers, how about marine biopolymers?  As the name goes, they are polymers produced by living organisms that live in the seas.  You may ask, how useful is it to us?  Aren’t all polymers similar?

Research has shown that marine biopolymers may serve as a potential base material for biodegradable plastics as well as applications in food additives, pharmaceutical and medical polymers, wound dressings, bio-adhesives, dental biomaterials, tissue regeneration and 3D tissue culture scaffolds. 

Universiti Malaysia Sabah’s Prof. Madya Dr. Charles S. Vairappan and his team has developed an innovative product called Profeed.  This is a probiotic fish feed which has been cleverly developed without costly sterilization by just using a concoction of probiotic microbes to do the job through fermentation. Another possible biopolymer that may be developed is by stressing certain bacteria to produce chemicals to make polymers.

Marine-derived biomaterials science is still relatively new and the marine environment is a relatively untapped resource for the discovery of new enzymes, biopolymers and biomaterials for industrial applications.

The Bright Darkness

I was standing at the entrance of the Dialogue in the Dark exhibition (currently at Petrosains, Level 4 Suria KLCC) and was nervously handing in my ticket to the employee as I attempt to visualize the experience ahead. It was something I never thought I would experience, but there I was with another family as we wait for our scheduled session to begin. We had a small chat and then, Vicky, one of the employees at the exhibition, gave us a brief introduction and history about Dialogue in the Dark. The exhibition has a wonderful history and track record, being in numerous countries the world over and changing thousands of lives. As time drew closer to 3 p.m., we gathered in front of a dark entrance covered by a curtain. We could venture into the new world only after we were taught how to use the cane. I gained slight confidence and well, thought it was easy and so took it lightly. Thus, I gathered all of my courage to enter another person’s world where darkness is the norm. 

Note: This is not part of the exhibition

The adventure only just began when my hands started to tremble. It was pitch black and losing my sight temporarily for the first time was horrifying.  It was just a few moments after we began our journey but we kept on asking each other, “Where are you?” It was clear that we have yet to adapt to the new environment which made us lose our coordination. We tried to calm down, but it was obvious that most of us panicked for a bit. Although we had Vicky to guide us in the beginning, I began to cast some doubts if she knew our whereabouts. We only had walls and the cane to help and steer us along the way. Soon after that, Uncle Jo, who was our guide throughout the exhibition, greeted us in the dark and gave us a warm welcome. Somehow, I felt at ease when Uncle Jo welcomed us and became our guide as we embarked on an adventure which is one of its kind.  

It would be a lie if I were to say I mastered the usage of the cane right away. We kept on bumping into each other and did not know where exactly the objects were as we experienced life blind like Uncle Jo did. Unlike us, Uncle Jo knows exactly where we were. He guided us with much patience and care. Who would have known that one with perfect physical abilities would be guided by a person who has a disability? 

We began to familiarize ourselves in the new world and see the aesthetics of life in a whole new perspective. It felt like my senses of touch were enticed! I liked the texture of the objects with what I could recall and this whole experience made me excited as I felt like I was in a maze. We could listen to the sound of nature that we are familiar with but there was something that I could not depict in words to express the wonder of seeing the beauty of the surrounding by ears and not by the eyes. Jason, who is an energetic visitor and also the youngest among all of us, was excited as he adjusted to the environment and he even helped to guide me alongside Uncle Jo. 

However, what impressed me more was Uncle Jo’s open-mindedness as he encouraged Jason to ask more questions and instill great interest in Jason to explore the world of darkness. I must say that all of us were inspired and learned to communicate under Uncle Jo’s guidance. It really felt like we were just talking to a friendly neighbour. We were given the chance to ask him questions about his life up-close and personal. I felt for his challenges living life blind as our world, especially in Malaysia, is biased to the sighted. We don’t often recognize the needs of the blind, deaf, or wheelchair bound so everyday life like shopping or going to watch a movie is so much more difficult for the less-abled. I did a self-reflection in the dark room and noticed how ignorant I was to complain about the imperfections I have. I seem to be way more incompetent than Uncle Jo as his spirit to live a normal life is greater than mine. 

Before we knew it, our meaningful and adventurous journey in the Dialogue in the Dark exhibition came to an end. We finally got to see the face of Uncle Jo under the light. He had a benign smile and one could see his warmness shining through. He managed to touch our hearts and brought us to a whole new look at life as we learn how to appreciate ourselves and understand the blind better. It was not merely an experience where we learn about them, but we were also given the chance to look at ourselves and appreciate life as it is. How impressive it was that an hour long experience is able to give me and the visitors a lesson that we would not otherwise get. Through Dialogue in the Dark, it feels like the blind are sharing their world with us and it was a privilege indeed.

Bake Your Ice Cream & Keep It Frozen

Are you a fan of “pavlova” or any other meringue based dessert? If you are, you can make it on your own. It is very easy and cheap!

To make your own meringue, all you need are an egg, a tablespoon of icing sugar, a few drops of vanilla essence and a tablespoon of lemon juice.

First of all, separate the egg yolk from its white. You only need the egg whites to prepare meringue. Then, place the egg whites into the mixing bowl and whisk it. Before start beating the egg white, preheat the oven to 250 degrees Celsius and place a baking paper on the tray. Start to beat the egg whites with a constant medium speed until the soft-peak stage. Now, add in the icing sugar, vanilla essence and lemon juice. Beat these ingredients at high speed until the mixture becomes stiff. 

To make a simple delicious dessert using the meringue you made, you just need a slice of your favourite cake and a scoop of your favourite ice cream. Scoop the ice cream and place it on the cake. Next, spread the meringue to fully cover the ice cream and make sure that it covers the whole ice cream smoothly. This is the key step in making a mouth-watering dessert! Place your cake slice on to the tray and bake it in the oven for about three to five minutes and voila!

You will realize that the ice-cream remains frozen even though it had been baked in the oven. Why? The secret is the meringue itself! As you whisk, it traps a lot of air in the mixture, thus making the meringue a good heat insulator. Heat travels quickly in food which is solid in nature. In the case of the meringue, it has lots of trapped air bubble, therefore its molecules are far apart from one another. As a result, the heat from the oven travels slower through it and this keeps the ice cream in its frozen state.

So, let's try to make one today!
