This document discusses the key branches and concepts of modern physics. It begins by outlining the objectives of becoming familiar with modern physics, stating the postulates of special relativity, and differentiating between inertial and non-inertial reference frames. The main branches of modern physics discussed are atomic and nuclear physics, quantum physics, relativistic physics, solid state physics, and plasma physics. Special relativity introduced ideas like time dilation, length contraction, and mass increase that defy common sense. The general theory of relativity further unified these ideas and proposed gravity is a manifestation of curved spacetime due to mass-energy and momentum.
Light travels in straight lines and very fast, faster than sound. We see objects because they reflect light into our eyes, while shadows are formed when light is blocked. There are two main types of reflection - specular reflection off smooth surfaces like mirrors, and diffuse reflection off rough surfaces. The law of reflection states that the incident ray, reflected ray, and normal to the surface all lie in the same plane, with the angle of incidence equaling the angle of reflection.
Light travels in straight lines. Shadows are formed when light is blocked by an object. The size and shape of shadows can change depending on the position of the light source and object. Reflection of light allows us to see objects when light bounces off their surfaces and into our eyes. Common examples of reflection include mirrors, water surfaces, and other shiny materials.
This document discusses key properties of light including reflection, refraction, diffraction, and interference. Reflection occurs when light bounces off a surface, following the law that the angle of incidence equals the angle of reflection. Refraction is the bending of light when passing from one medium to another at different speeds. Diffraction causes light to bend around barriers depending on the wavelength and barrier size. Interference results from the interaction of crests and troughs of light waves, producing constructive or destructive interference.
Light is an electromagnetic wave that consists of oscillating electric and magnetic fields and can travel through space. It spreads in straight lines and carries energy. Light sources such as the sun emit light, while objects that do not emit light themselves are called dark bodies. When light hits surfaces, it can be reflected, absorbed, or pass through depending on whether the surface is opaque, translucent, or transparent. The law of reflection states that the angle of incidence equals the angle of reflection. Shadows form when light rays are blocked by an opaque object.
The document discusses several key properties of light, including:
- Reflection - Light bounces off surfaces at the same angle it hits.
- Refraction - Light bends as it passes from one medium to another, changing speed. The degree of bending depends on the medium's index of refraction.
- Interference - When two light waves meet, they can constructively or destructively interfere based on how their crests and troughs align.
It explores light's dual nature as both a wave and particle, demonstrated through experiments like Young's double-slit experiment showing light's wave-like interference patterns, and the photoelectric effect showing its particulate properties.
Light travels in straight lines until interacting with objects. It can scatter, reflect, refract, or be absorbed. Reflection causes light to bounce off a surface at the same angle. Refraction causes light to change speed and direction when passing from one medium to another, such as from water to air. Absorption occurs when light is taken in by an object and its energy is transferred to heat.

After most students passed a summative test but some failed, strategic intervention material (SIM) is recommended to help students master skills they did not develop in regular classes. SIM uses learning strategies and content enhancement for students and teachers, respectively, and requires less supervision than regular classes. SIM focuses on specific skills not mastered by students and may cover different topics than regular classes. It includes guide cards, activity cards, assessment cards, enrichment cards, and reference cards to engage students and assess their mastery of skills. Teachers should ensure SIM activities align with objectives and keep activities short, simple, and varied to accommodate different learning styles.
The document discusses the importance of conserving the Pasig River in the Philippines. It notes that overpopulation and poverty have damaged the river, turning it brown in the 1990s. Pollution from garbage and waste from communities living along the river have affected water quality. However, despite being polluted, the river remains important for transportation and livelihoods. The document calls for unity in conserving and saving the Pasig River for future generations.
The solar system consists of the Sun and objects that orbit it, including 8 planets. The Sun is by far the largest object, containing 99.86% of the mass of the entire system. The planets range from Mercury, the smallest and closest to the Sun, to Neptune, the farthest. Other objects in the solar system include dwarf planets like Pluto, asteroids that orbit the Sun between Mars and Jupiter, meteoroids that become meteors as they burn up in Earth's atmosphere, and comets that have highly elliptical orbits around the Sun.
This document provides a history of astronomy from ancient Greece to modern times. It describes how early Greek astronomers like Aristotle and Hipparchus made early observations of celestial objects but believed in a geocentric model where Earth is the center. Ptolemy later created an elaborate geocentric model, though Copernicus, Kepler, and Galileo provided evidence supporting a heliocentric model through observations, Kepler's laws of planetary motion, and Galileo's discoveries with the telescope. Newton later unified physics and astronomy by formulating the law of universal gravitation. Einstein then revolutionized our understanding of motion, space, and time through his theory of relativity.
This document provides information on various astronomical tools. It describes different types of telescopes such as refracting telescopes which use lenses and reflecting telescopes which use mirrors. It discusses radio telescopes, space telescopes, and notable space telescopes such as Hubble, Chandra, and Fermi. Space probes, rockets, spaceshuts, rovers, and observatories are also summarized. Important early space missions involving animals and astronauts are mentioned.
This document appears to be an individual worksheet for observing 7 learning stations that demonstrate Newton's laws of motion. The stations include getting nuts into a bottle, a car and dummy crash, getting hit from behind in a car, forces on a carousel, increasing mass effects, increasing force effects, and measuring forces in a tug of war using a spring balance.
This unit plan aims to teach 4th year high school students about Newton's laws of motion through various hands-on activities relating to land transportation, sports, and daily life. Students will discover principles of land transport, road safety, and vehicle design. They will also evaluate air quality in Metro Manila and the environmental impact of different transportation methods. Learning stations will provide opportunities for students to apply Newton's laws through tasks like creating a documentary, newsletter, or presentation. A mini-exhibit at the end will showcase student work and encourage appreciation for integrating activities into lessons. The unit utilizes the POEA strategy and various materials to create an engaging and meaningful learning experience for students.
This document is a problem solving record sheet from Makati High School. It includes fields for the group number, leader, members, activity title, description of the problem, type of problem, steps taken to solve the problem, a sketch or diagram of any device or model constructed, what the group found out from their work, and recommendations to improve the design or model.
This document provides a rubric for evaluating video presentation projects at Makati High School in the Philippines.

Projects will be graded out of 50 points and must be submitted by a deadline before a mini-physics Olympics event.
This experiment involves hanging different masses from a rope attached to a cart. Doubling the mass from 100g to 200g affected the motion of the cart. The procedure had the student double the mass and observe how it impacted the cart's movement. They were then asked what would happen if the force was doubled instead of the mass.
The document describes a procedure using an NXT robot to operate a carousel. Pressing the start button causes the attached wheels to reverse direction as the motor changes rotation. To prevent the wheel from reversing, modifications must be made to the motor or wheel attachment to ensure consistent rotation.
Cart A was released down a ramp, hitting cart B from behind. The matchbox on cart B moved forward as cart B received a force from the impact of cart A hitting it from behind, pushing it forward. The matchbox on cart A remained in the same position as cart A moved down the ramp and hit cart B, transferring its kinetic energy to cart B on impact but not affecting its own cargo.
This document provides guidance on developing and using strategic intervention materials (SIM) for students who did not master certain concepts during regular classroom lessons. SIM consists of several parts, including a guide card to introduce the topic, activity cards outlining tasks for students to develop skills, assessment cards to evaluate learning, enrichment cards for additional practice, and reference cards. When developing SIM, teachers should ensure activities are aligned to objectives, provide clear directions, include a variety of learning styles, and allow sufficient practice opportunities. The goal of SIM is to provide remedial learning through fun and engaging materials to help all students achieve competency.
