What is Physical Science? • Science is the way of learning about the natural world. • Physical Science is the study of matter, energy, and the changes they undergo. • Matter is anything that has mass and takes up space. • Energy is the ability to do work.
Chemistry is the study of the properties of matter and the changes they undergo. • Physics is the study of matter and energy and how they interact.
How Scientists Think… • They use skills of observing, inferring, and predicting to learn more about the natural world.
Observing Observing means using one or more senses to gather information. Two Types: • Quantitative observation • Qualitative observation
Quantitative observation involves numbers. Example: measuring your height or weight. • Qualitative observation describing what you see; doesn’t involve numbers. Example: Noticing that the ball is round or the stove is hot
Inferring • When you explain your observation, you are inferring. • To infer is to make a hypothesis based on what you observed. Example: If you come in and do not see the Bell Ringer up on the projector, you would probably infer that you will not have to do a Bell Ringer today.
Predicting • Predicting means making a forecast of what will happen in the future based on past experiences or evidence. Example: If Charles continues to rob stores, he will get caught. OR It’s cloudy outside, so it will probably rain.
Question • How can I identify the properties of a Twizzler using both qualitative and quantitative observations?
