  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. – ______, ______, _______, _______
