This document provides an overview of physical science, including its branches and key concepts. Physical science deals with non-living matter and energy, and has two main divisions: physics and chemistry. Physics studies changes in matter and energy, while chemistry examines changes in matter including structure, composition, and properties. Some important branches of physical science are geology, astronomy, meteorology, and mineralogy. The document also discusses scientific inquiry, forces and motion, work, energy, heat, and simple machines.
Scientific method vocabulary
The document defines key terms used in the scientific method and various sciences. It provides definitions for science, the scientific method, hypothesis, observation, properties, experiment, variable, control, conclusion, prediction, fact, technology, earth science, physical science, refine, theory, and law. It also notes that theories do not become laws, and laws did not start as theories.
1.1 What is Physics?
Physics is the study of the physical world and how it behaves. It can be broken down into seven main categories including mechanics, thermodynamics, optics, and electromagnetism. The scientific method involves making observations, formulating hypotheses, testing with experiments, and drawing conclusions. Models are used to simplify complex physical systems and guide hypothesis building and experimental design by focusing only on relevant characteristics.
Scientific Method
The document discusses the scientific method and how it has evolved over time. It begins by defining science as the empirical study of nature. It then discusses three main methodologies in science: reductionism, which explains phenomena in terms of underlying mechanisms; structuralism, which studies complex phenomena as original systems; and "universalism", which makes statistical predictions about classes of similar systems. The document traces how these methodologies have developed from classical physics to modern fields like quantum mechanics and biology. It also explores how mythologies can provide metaphorical insights that inspire scientific hypotheses.
Chemistry
Chemistry is the science of the composition and structure of matter and the changes matter undergoes. It is the study of atoms and molecules that make up all materials in the universe, from walls and paper to plants and animals. Chemical research relies on experiments conducted in a controlled manner to observe natural phenomena, identify regularities or patterns, and develop laws and theories to organize knowledge and predict future events. The scientific method involves making hypotheses based on experiments, testing them through further experiments, and developing theories that explain basic natural phenomena.

Introduction to Science and Chemistry
1. Science is a way of exploring and explaining the natural world using a process designed to reduce errors. It consists of various disciplines that study either physical phenomena like physics and chemistry or living organisms like biology.
2. The scientific method involves making observations, asking questions, developing hypotheses, making predictions, testing predictions through experiments, analyzing results, and peer reviewing findings. It allows scientific understanding to advance through evaluation and dissemination of information.
3. Scientific theories are hypotheses that have been rigorously tested and accepted as generally correct, but cannot be proven absolutely. Laws summarize scientific facts about nature. The body of scientific knowledge is stable but open to improvement through testing.
Science
Science is the systematic study of the structure and behavior of the physical and natural world through observation and experiment. Some careers in science include meteorologist, geochemist, ecologist, volcanologist, science illustrator, and oceanographer. The scientific method involves asking a question, making observations, forming a hypothesis, experimentation, collecting data, analyzing results, and communicating findings. Physical models represent systems visually, mathematical models use mathematical concepts and graphs, and conceptual models represent systems through interrelated concepts. Scientific theories are well-substantiated explanations based on repeated observations, while scientific laws describe what happens in nature without explaining why.

physical science senior high Q2 WEEK 2.pptx
This document discusses Aristotle and Galileo's concepts of vertical, horizontal, and projectile motion. Aristotle believed vertical motion was natural motion where objects return to their natural state, while horizontal motion required a force. He viewed projectile motion as initially vertical then horizontal. Galileo disagreed, finding that objects fall at the same rate in a vacuum and horizontal motion requires no force if unimpeded. The document then discusses Newton's laws of motion, including inertia, force and acceleration, and action-reaction. It also covers conservation of mass, energy, and momentum. Motion graphs are introduced to aid interpretation of motion.
Physics introduction

Science and technology work together, with science exploring nature through experimentation and technology applying scientific knowledge to improve human lives. The environment includes all surrounding factors that affect living things, and consists of both biotic elements like plants and animals as well as abiotic elements such as air, water, and soil. Ecosystems link biotic and abiotic components through energy and nutrient cycles.
earthandlifescienceintro week 1.pptx
This document provides definitions and descriptions of key concepts in earth and life science. It defines science as using systematic methods like observation and experimentation to study the natural world. It then discusses the universe and branches of science like space, time, energy, matter, and dark matter. Space is described as the three-dimensional extent in which objects have position and direction. Time is the progress of existence from past to future. Energy must be transferred to objects to cause change, and is conserved. Matter occupies space and has mass. Dark matter is estimated to make up 85% of the universe's matter.
How did our understanding of gravity change over
Our understanding of gravity has changed significantly over time. Early Greek philosophers like Aristotle believed objects fell because their natural place was on the ground. Galileo later found that all objects accelerate at the same rate in a vacuum and rejected Aristotelian physics. Isaac Newton then proposed his law of universal gravitation, describing gravity mathematically and applying it to both Earthly and celestial motions. While Newton accurately described gravitational effects, modern physics has since shown his laws break down at very high speeds, where Einstein's theory of relativity is needed to fully explain observations.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
