Strand 101

Out of all the strands in senior high, STEM seems to stand out more than the other ones. With a much wider range of courses within the scope of the strand, STEM tackles almost all of essential lessons in order to prepare the students for their college courses in the future. Different branches of mathematics and science does have a wider scope of terminologies, but here are some of them:

Calculus - branch of mathematics concerned with the calculation of instantaneous rates of change (differential calculus) and the summation of infinitely many small factors to determine some whole (integral calculus).

Example: Calculus in mathematics is generally used in mathematical models to obtain optimal solutions and thus helps in understanding the changes between the values related by a function.

Engineering - is the designing, testing and building of machines, structures and processes using maths and science.

Example: Engineering is the application of science and maths to solve problems.

Experiment - a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.

Example: Performing experiments are essential when you want to learn more about chemistry.

Chemistry - science that deals with the composition, structure, and properties of substances and with the transformations that they undergo.

Example: Learning the Lewis Structure is one of the first ways to improve in advancing in chemistry.

Electricity - is a type of energy that consists of the movement of electrons between two points when there is a potential difference between them, making it possible to generate what is known as an electric current.

Example: In order for the simple circuit to work, a source of electricity is required such as battery.

Cell - the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.

Example: Cells can be classified into different types such as but not limited to plant cells and animal cells.

Vector - is a quantity that has two independent properties - magnitude and direction.

Example: 8 m/s, west is an example of vector quantity, whilst 8 m/s is only a scalar quantity.

Trigonometry - branch of mathematics that studies relationships between the sides and angles of triangles.

Example: There are six (6) functions of an angle commonly used in trigonometry, namely sine, cosine, tangent, cosine, cosecant, and cotangent.

Heredity - the passing on of physical or mental characteristics genetically from one generation to another

Example: Heredity will explain about two blue eyed parents having brown eyed offspring.

Gene - are made up of sequences of DNA and are arranged, one after another, at specific locations on chromosomes in the nucleus of cells.

Example: Gene composition determines why some illness runs in a family.

Social media towards information dissemination in times of calamity

In times of calamity, communication between different groups of people is crucial to disseminate information about proper procedures and updates with regards to the disaster. Since the social media starts to be integrated to our daily lives, not only does it provides entertainment, it includes access to effective and efficient communication as well.

Some of the ways social media has helped include but not limited to:

Rapid Communication

With the current applications and instruments available for everyone to use, communication between two or more groups of people have become highly effective and efficient. And in times of calamity, social media allows quick spread of information which can inform wide scope of people about updates, procedures, and can alert a large population. Although past mediums of information dissemination such as tv, radio, and print can reach a much wider population, the requirements to spread information (electricity, face-to-face interaction, etc.) may not be available in times of disaster.

Access to Real-time News

In addition to rapid communication, social media also allows immediate connection to one or more individuals. This is crucial for sudden changes to the calamity and the environment. Government agencies such as but not limited to PAGASA, PHIVOLCS, and NDRRMC. Since these agencies have immediate knowledge to the calamity, the very next thing they have to do is to disseminate the information in which social media has its use.

Advantage over Traditional Medias

Although traditional medias hold it's significance when it comes to information dissemination, social media has more advantages when it comes to the same purpose. Social media offers instant update which allows people to be alert at all times. Unlike traditional media which can only disseminate information later than the latest update, which is undoubtedly a huge drawback.
