Department of Mathematics and Science Practicing Science: Observing the Natural World of Matter What Is Matter? MatterMatter is the material or “stuff” everything is made of. What are you doing if you are observing matter? Observing matter means to carefully explore all of its properties. Look around the room and identify some matter. What are some physical properties matter can have?properties Color, texture, odor, shape… What are two properties that all matter share? All matter has mass and takes up space.masstakes up space What are the three states of matter?states of matter solid, liquid, and gas

Department of Mathematics and Science What physical properties do all solids have in common? solids The particles in solids are close together and vibrate in place. For this reason: A solid has its own definite shape and definite volume. A solid keeps its shape even when it moves.

Department of Mathematics and Science What physical properties do all liquids have in common? liquids The particles in liquids are not as close together as the particles in solids and move more freely than particles of solids. For this reason: Liquids have a definite volume. Liquids take the shape of their container. Liquids can be poured from one container to another.

Department of Mathematics and Science What physical properties do all gases have in common? gases The particles in gases move freely in all directions. For this reason: Gases have no definite size or shape. A gas take the shape of its container. A gas will fill all the space inside a container. Three States foldable Three States Venn diagram

Department of Mathematics and Science Observing and Measuring Matter Center Choose an Object to Observe Thumb Pencil Book Desk Chair Penny Drop of Water Rock Shell Plant Leaf Flower Other Choose an Observation Type List as many properties as you can about that object. What do you observe about that object quantitatively? What are all the things you observe directly about….? Describe how this object looks, feels, sounds, and/or smells.
