This chapter explores the fundamental concepts of matter, mass, and volume. Matter is defined as anything that can be physically touched, encompassing all objects and living things in the universe. Mass is a measurement of how much matter is present in an object, while weight refers to the gravitational pull on that mass. This chapter also discusses the concept of volume, calculated through the formula length x width x height, and explains how to determine the volume of irregularly shaped objects using displacement. Learn how these concepts are interconnected!

Chapter 1.1 Matter, mass, and volume
Brain Pop • Example: Which has more mass, a car or a cat? Why?
Matter • Things that can physically be touched • It makes up all objects and living things in the universe • Examples: people, animals, water, etc.
Mass • Measurement of how much matter there is • The more matter, the greater the mass. • Example: Which has more mass, a car or a cat? Why?
Weight • Is the downward pull on an object due to gravity • Gravity is a force that pulls all matter (things that can be touched) together • Example: car and a cat.. Which has more matter?
Mass –vs- Weight • Again Mass describes the amount of matter an object has and Weight is how strongly gravity is pulling on that matter.
Volume • The amount of space that matter occupies (takes up) • Volume = length X width X height • V=l x w x h • Not regular in shape, can figure out the volume by Displacement • No two objects that are the same can be in the same space at the same time
