Understanding Physical Science: Exploring Matter and Energy

Chapter 1 introduces physical science, a field dedicated to understanding the natural world through observation, data gathering, and analysis. It highlights the study of matter—anything with mass and volume—and energy, which is defined as the ability to perform work or induce change. The chapter delves into the realms of physics and chemistry, explaining their focus areas and the importance of scientific skills such as observing, inferring, and predicting. Through qualitative and quantitative observations, scientists interpret their surroundings to better explain the phenomena of the natural world.

  1. Chapter 1 What is Physical Science?

  2. Introduction • ____________ is a way of learning about the natural world by gathering information. • Our “Science Question of the Year” is _________.

  3. The Study of Matter and Energy • What is physical science? • Physical Science is the study of _______, _________, and the changes they undergo. • Matter is anything that has mass and occupies space. • Energy is the ability to do work or cause a change.

  4. The Study of Matter and Energy • Physics is the study of matter and energy and how they interact. • Physics deals with _________ and _________ an how they are related. • Other topics within Physics are: • Sound • Light • Electricity • Magnetism

  5. The Study of Matter and Energy • Physical Science is divided into two main areas of study : _____________, ______________ • Chemistry is the study of the properties of matter and how matter changes. • Review Question- What is matter? • What kind of jobs do a chemist have?

  6. How Scientists Think • Scientists use skills of OBSERVING, INFERRING, and PREDICTING to learn more about the natural world. • Observing • Observing is using one or more senses to gather information. • The five senses are: __________ __________ __________ __________ __________

  7. How Scientists Think • There are two types of observations • Qualitative observations- descriptions that do not involve numbers of measurements • i.e. – ______, _______, _______, ______ • Quantitative observations – measurements using numbers • i.e. – ______, ______, _______, _______

  8. How Scientists Think • Inferring • Our explanations of our observations are called our inference. • Inferring is the explanation or interpretation of the things you have observed. • Inferences are based on reasoning from what you __________know Inferences can be very misleading and/or incorrect

  9. How Scientists Think • Predicting • Predicting is making a forecast of what will happen in the future based on past experience or evidence. • !!! If you are predicting without experience or evidence then you are guessing !!!
