Brush Your Teeth!

 ... and reduce the risk of heart attack!

We already knew that maintaining a high level of oral hygiene is good for your teeth.

But at Columbia University in America, they have discovered that brushing your teeth also helps reduce the risk of cardiovascular disease. 

Researchers analysed  


of 657 
Also noted the thickness of  

Carries blood from the 
to the 
The width of this artery is a good indication of arteriosclerosis when cholesterol or other substances nestle in the walls of the carotid artery. 
When this happens, the blood flow can be affected and even stop.

So, did the researchers find a connection between oral hygiene and healthy arteries?

The more bacteria a gum infection creates, the thicker the carotid artery. 

That means the increase in stroke or heart attack. 

The researchers suspect that the bacteria travel through the body from the mouth via the blood and cause infections which close the arteries. 

How to avoid this?

1. Good brushing
2. Flossing

Are There Dinosaurs in Malaysia?

What are dinosaurs?

Dinosaurs are a diverse group of reptiles that lived from about 243 million years ago to 65 million years ago, during a time on earth we call the Mesozoic era. The clade Dinosauria consists of non-avian dinosaurs and avian (feathered)-dinosaurs that are birds that continued to exist past the K-T extinction event, but for this science fact, we will be referring to the non-avian dinosaurs only.

How do we know they existed?

Fossils of dinosaurs had been discovered around the globe, to an extent that a dinosaur discovery revolution started in the 70’s. In February 2014, a 145-75 m.y.o. spinosaurid tooth fossil was found in an undisclosed dig site in Pahang by a team of University Malaya and Japanese scientists.

Paleontology teams from UM, UKM, University Malaya Kelantan and Universiti Teknologi PETRONAS had discovered dinosaur tooth fossil of a dinosaur from the Ornithischian order, dinosaur tracks (of possible sauropods) and bone fossils from Sungai Cicir, Gunung Gagau and Tasik Kenyir in Terengganu.

Which period is significant in Malaysia?

Rocks from the Mesozoic era, which spanned 252 to 66 million years ago and cover the Triassic, Jurassic and Cretaceous periods are all available in Malaysia, though not in all states. It is easier to discover fossils from the Cretaceous periods because newer fossils are more well-preserved.

Why is This Science Important / Relevant to Us

The science of dinosaurs is a worldwide cultural phenomenon. It is a field of study that intrigues a lot of public interest towards certain sciences. Its popularity allowed the awareness of dinosaur sciences be raised among the public and can be used in movies, theme parks, museums and many other forms of public attractions and entertainment. 

The study of dinosaurs helps us to understand the history of our planet earth: allowing us to predict the circumstances of future events on the planet in comparison to past events. This study allows us to understand living things in the present better. For example, the study of dinosaurs allows us to question the function of feathers on modern-day birds, because most feathered dinosaurs did not have their feathers functioned for flight. The study of dinosaurs also allows us to compare the magnitude of today’s extinctions (whereby every year some species of animals go extinct) with that of the dinosaurs’ since the dinosaurs were involved in the K-T extinction event.

Aside from that, a lot of fresh discoveries were carried out in untapped locations. For example, the some largest dinosaurs to ever walked the earth (such as Argentinosaurus) were uncovered in South America. Discoveries in India helped us understand the hazardous environmental conditions and natural disasters during the Cretaceous period. Madagascar’s discoveries helped us understand cannibalistic dinosaurs. Antarctica was where dinosaurs that could survive extreme cold were discovered. In China, dinosaurs with feathers were abundantly discovered. Who knows what kind of new discoveries we can get in Malaysia.

Dinosaur discovery in Malaysia is yet to be classified, therefore here are some pictures of dinosaurs from similar groups to get a rough idea what kinds of dinosaurs had been discovered in Malaysia.

 Spinosaurid tooth found in Pahang in 2014.

 Example of a fish-eating spinosaur: Suchomimus from Africa.

Ornithischian tooth found in Terengganu in late 2014.

 Example of a plant-eating dinosaur from the Ornithischian order: Zalmoxes from Romania

 (Possibly) Sauropod track fossil found in Terengganu in 2014.

 Example of a plant-eating sauropod: Argentinosaurus from Argentina.

Map of Late Cretaceous (~66 mya).

Similar dinosaurs were distributed in the southern regions i.e. South America, Africa, Europe and Southeast Asia such as sauropods, spinosaurids, and abelisaurs. Ornithischians were widely distributed around the globe, though the crested hadrosaurs, thick-headed pachycephalosaurs, and ceratopsians were more commonly distributed around the northern regions i.e. China, Russia and North America, along with the famous tyrannosaurs.

Today, distribution in animal species can be seen around the globe, e.g. marsupials can only be found in Australia.

Breakout EDU Digital

An Immersive Learning Game Platform

Ever heard of Escape Room, a physical adventure game where players are required to solve a series of puzzles in a given time to get out of an area they are locked in? 

Breakout EDU Digital is another similar version of Escape Room but it focuses more on the educational value received by players upon completing the game. 

A prevalent difference between Breakout EDU Digital and Escape Room is that it mainly operates on a digital platform which in this case using G Suite for Education apps and tools (For e.g. Google Sites, Google Forms, YouTube). 

Innovative Way To Promote High Order Thinking Skills (HOTS) 

All Breakout EDU Games are designed to not only encourage players to apply their knowledge and problem-solving skills but require them to use the Four Cs; critical thinking, collaboration, creativity and communication. 

The gameplay is specifically designed to fit the needs of learners or students with an array of interesting clues, mysteries and also storylines which contains elements that capture the interest of today’s younger audience. 

What is needed to conduct a Breakout EDU Digital?

In order to conduct a Breakout EDU Digital, you need:
Stable WIFI connection
Smart devices

How is the game played?

Players are required to collaborate with each other to solve a series of digital puzzle problems in order to unlock a locked box which manifests in this game as a Google Form. Before starting the game, players are provided with a one-page Google Site which contains text, images and clues. 

Screenshot of one of the games featured on https://www.breakoutedu.com/digital

As you can see from the above screenshot, there is a story followed by a Google Form with the locks and an image. Clues are also hidden among the words in the story.

These text, images and clues are mainly deployed to players using G Suite for Education apps and tools; mainly using Google Forms, Google Drawings, Google Drive and YouTube. Answers are submitted on the Google Form embedded in the site through a series of ‘lock’ questions. Players will be unable to ‘breakout’ unless all locks have been unlocked. 

Saving Nasi Lemak Breakout EDU Digital Game

A Malaysian-inspired Breakout EDU Digital Game has been created! 

Featuring Malaysia’s national dish and sweetheart, Nasi Lemak, the game is set to quiz players’ minds with its mind-boggling mathematics questions. Each question is specifically and creatively designed to fit the Nasi Lemak theme. The questions are of Malaysian secondary school students level and can also be answered by adults. 

Upon access to the Google Site, players will be greeted with a mouth-watering banner of Saving Nasi Lemak Game. A story and a Powtoon video usher players further into the game.

Reshuffling Molecules

Ever broken an egg before? Notice the soft, transparent, slimy part? This is called the albumen, which contains a lot of proteins; in fact, it has over 10 different kinds of proteins that are very beneficial to our bodies. But what happens when you heat egg in a pan? 

The molecules of proteins can be arranged in different forms. The arrangements of these molecules are determined by the type of bonds that hold them up together. Imagine weaving or bonding pieces of thread into cloth. And then, this piece of cloth can be turned into a shirt with more stitching or bonding. 

What happens when you heat up the egg white is that some bonds are broken, and the molecules are rearranged. This new structure is more stable than the raw egg white. 

The same thing also happens when you heat up butter. Butter is in solid form because of bonds that hold them close together. But these bonds are broken when given heat and the molecules rearrange themselves in the form of oil, which is a liquid form. When you introduce hydrogen molecules into peanut oil, the molecules of the oil will be rearranged, and you get peanut butter! 

Water in its solid form is called ice. The molecules are packed tightly together and are held by many bonds. These bonds, however, will be broken by heat and the water molecules start to become loose. The ice will eventually lose its shape and turn into a liquid form.

When you heat up lemon juice, it will turn brown because the molecules are rearranged with oxygen molecules. This is the explanation for the experiment below. 


Experiment: To make invisible ink

lemons, cotton buds or paintbrush, white paper, electric iron, ironing board.

1.    Cut the lemon in half and squeeze the juice out into a container.
2.    Dip the cotton bud or paintbrush into the lemon juice and use it to write your name on a piece of clean white paper. Repeat this 3 times.
3.    Allow the paper to dry.
4.    Once dried, iron over the paper until you see your name appear in brown. 

Glossary of Terms:
Albumen [al-byoo-muhn] the white of an egg.
Bond [bond] something that binds, fastens, confines, or holds together.
Molecule [mol-uh-kyool] the smallest unit of an element or compound.
