Celebrating innovation, curiosity, and critical thinking as our Senior High School students showcase their scientific minds at the Science Fair.”

Earlier today, Grade 11 and 12 STEM students demonstrated their creative minds by building fun games that help students engage in Science. Using this event, students can show others how science can be fun. This event helps students not only academic but also show their perseverance, curiosity, and scientific spirit. May your inventions be an inspiration for others to follow the path of science.

Happy birthday sir

John Dalton (1766 – 1844)

Who he was: John Dalton was an English chemist, physicist, and meteorologist, best known as the founder of modern atomic theory.

Birth & Early Life: Born on 6 September 1766 in Eaglesfield, a small village in England, into a Quaker family.

Education & Work: He started as a school teacher at a very young age and later became a lecturer in mathematics and natural philosophy.

Major Contributions:

1. Atomic Theory (1803–1808)

Proposed that all matter is made up of tiny indivisible particles called atoms.

Each element is made of identical atoms, unique from atoms of other elements.

Atoms combine in fixed ratios to form compounds.

His theory laid the foundation of modern chemistry.

Molecules → Groups of atoms

Atoms → Smallest unit of matter

Protons → Positive particles in atoms

Quarks → Building blocks of protons & neutrons

Strings → Tiny vibrations (theory of everything!)

ATOMIC MODEL THROUGH HISTORY

1. John Dalton’s Model (1803) – Solid Sphere Model

Overview:

Dalton proposed that all matter is made up of indivisible particles called atoms.

He imagined atoms as tiny, solid spheres—like billiard balls.

Key Ideas:

Atoms of the same element are identical in mass and properties.

Atoms cannot be created, divided, or destroyed.

Compounds form when atoms of different elements combine in fixed ratios.

Importance:

First scientific model of the atom based on experimental evidence (like gas laws).

Laid the groundwork for modern chemistry.

---

2. J.J. Thomson’s Model (1904) – Plum Pudding Model

Overview:

After discovering the electron, Thomson proposed that atoms are made of a positively charged substance with negatively charged electrons scattered within it—like raisins in pudding.

Key Ideas:

Atoms are divisible.

Electrons are negatively charged subatomic particles.

The rest of the atom is a blob of positive charge to balance the electrons.

Importance:

First model to show that atoms have internal structure.

Introduced the idea of subatomic particles.

---

3. Ernest Rutherford’s Model (1911) – Nuclear Model

Overview:

Conducted the gold foil experiment where alpha particles were fired at a thin sheet of gold.

Most passed through, but some were deflected at large angles.

Key Ideas:

Atoms are mostly empty space.

A small, dense, positively charged nucleus is at the center.

Electrons orbit around this nucleus.

Importance:

Disproved the plum pudding model.

Introduced the concept of a nucleus.

---

4. Niels Bohr’s Model (1913) – Planetary Model

Overview:

Bohr expanded on Rutherford’s model using discoveries from quantum theory.

Key Ideas:

Electrons orbit the nucleus in fixed paths or “energy levels.”

Each level has a specific amount of energy.

Electrons can jump to higher levels when energy is absorbed and fall back down when energy is released (as light).

Importance:

Explained why atoms emit light in specific colors (atomic spectra).

Added the concept of quantized energy levels.

---

5. Erwin Schrödinger’s Model (1926) – Quantum Mechanical Model (Electron Cloud Model)

Overview:

Schrödinger used complex math to describe the behavior of electrons as waves, not particles in orbits.

Key Ideas:

Electrons exist in regions called orbitals (not fixed paths).

Orbitals show where an electron is most likely to be found.

The exact location and speed of an electron cannot be known at the same time (Heisenberg Uncertainty Principle).

Importance:

Most accurate and widely accepted model today.

Forms the basis of quantum chemistry and modern physics.

"📢 LICEANS! Periodical exam recap time 📝😜"

Kamusta exams, liceans? Tara! Ating balikan 🤪

🎯 Reactions after the test:
👍 Okay lang, chill lang parang walang nangyari 😎
😂 Umabot lang sa stock knowledge, thank you Google (pero bawal mag-open notes 😅)
😯 Sana pasado… lalo na sa’yo ❤️🔥
😭 Mahirap, nakakaiyak… gusto ko na lang magtanim ng gulay sa roblox 🌱
🥰✨ I did my best, bahala na si teacher!

Pero kahit anong feels mo after the exam, isa lang ang totoo: Liceans = SURVIVORS 💪🔥
Kung may award lang for "Best in Hugot After Exam"🏆, tayo na panalo!

🌟 Science Trivia of the Day! 🌟
🪐 Did you know?
A day on Venus (one full rotation on its axis) takes about 243 Earth days…
But a year on Venus (one full orbit around the Sun) is only 225 Earth days! 🤯

That means a day on Venus is actually longer than its year.
