Introduction to Physical Science Chapter 1, Section 1
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.
Twizzler Lab
