Tip No. 4: Always keep the references of your research

Always make sure to copy the website link or URL of the articles you found on the web.
If its a book, then copy it's title, author, publisher and year of publication.
It is important, especially if you need to find it again.

Tip No. 2: E-mail as an Online Data Storage

Kapag nagre-research through internet [online], mahalagang mayroon ka pinagtataguan ng mga nare-research mo na online din. Therefore I suggest na gumawa ka ng e-mail. This time, you should have realized na hindi lang sa paggawa ng account sa Facebook or Twitter may silbi ang e-mail.

Maaaring mag-upload or mag-save ng mga document files sa e-mail, tulad ng Microsoft Word, Excel or Powerpoint Files. Puwede din mag-upload or mag-save ng images, audio and video files.

Maaari ding isend ang mga files na ito sa ibang may e-mail din. So I suggest na gumawa na kayo ng e-mail. Heto ang mga sites na nag-o-offer ng free e-mail account.

Tip No.1: How to easily memorize names and dates

Ok guys... hindi ninyo kailangan kabisaduhin ang bawat lecture na ipapasulat sa inyo ng inyong teacher... Maniwala kayo o sa hindi, ang tanging sikreto ay ang "maluwag sa loob na pag-unawa" sa tinuro ng teachers ninyo. Sabihin nating may mga taong mahirap talaga makatanda ng maraming detalye, pero di ninyo kailangan mawalan ng pag-asa. Ayaw ninyo ng History dahil napakaraming dates at pangalan ng tao na dapat tandaan? Maaari ninyong gawin ito: gawin ninyong mga tauhan sa isang palabas ang mga dapat tandaang gawin ninyong related sa inyo ang mga detalye tungkol sa kanya...

Halimbawa: Jose Rizal, pinanganak noong June 19, 1861

At ganito ang paraan para tandaan siya:

Ah, pambansang bayani natin, si Jose Rizal, sino ba ang hindi nakakakilala sa kanya? Basta ang alam ko, kaBirthday siya ng crush kong si Lea, June 19 din, tapos parehong 61 ung dulo ng taon kung kelan sila pinanganak ng nanay ko, 1961 kasi ang nanay ko... so malamang 1861 naman si Rizal kasi hindi p…

Science: Relationship between Electricity and Magnetism

Relationship between Electricity and Magnetism

1. When a current passes through a coil of wire, it generates a magnetic field along its axis. This was discovered by Hans Christian Dersted

2. If a loop of wire is moved through a magnetic field, a current is induced in the wire (ex. transformer, generator). Discovered by Michael Faraday

The magnet, in the ancient times, was called lodestone.

Science: Law of Conservation of Charges

Law of Conservation of Charges
By Benjamin Franklin In an isolated system, the total charge is conserved.  Materials can acquire charges when/through:
Friction/rubbing (static electricity) Placed near/on contact with a charged body Induction, that produces a charge when there is a redistribution of charges Ionization, the formation of cation (+) and anion (-)

Literature: Types of Poetry

Narrative - tells a series of eventsEpic - long, unified narrative peom, story of warrior, king or god in which:protagonist is larger than lifetwo dimensional [the good and the bad]more than human strengthsetting covers up to universemay provide historical fact/placegods/divinities were involvedadventure adheres to central themeMetrical romance - story of knights [example: Beowulf]Metrical TaleBallad - narrative poem meant to be sangLyric - honors its musical originOde - peom of praiseElegy - poem for the deadSonnet - iambic pentameter [14-lined poem]Song - set to musicSimple lyric - poet’s thoughts, emotions and feelings

Mechanism of Organism Evolution
variation and natural selectiongenetic drift (migration) - accidental changes in frequency of genesadaptive radiation - rapid multiplication of related species each with specializationsallopatric speciation - developments of new species as a result of geograpical isolation which prevents interbreedingmutation - alteration or change of DNA

Science: Biology - Darwin’s Theory of Natural Selection

Darwin’s Theory of Natural Selection

Origin of “species” book, all organisms have the tendency to overproduce in reproduction; however, the total population seeme to remain about the approximate number; hence, competition exists; survival of the fittest.
species have the ability to produce large number of offspringsresources of the natural world is limitedorganisms have to competeno two individuals are exactly alikeorganisms that have survived and produced offspring are those that inherited beneficial traits for survival
