2. IDENTIFYING SOLIDS, LIQUIDS, AND GASES MRS. CARONE 3RD GRADE SCIENCE ACTIVITY

3. OBJECTIVES: Students will identify the properties of different types of matter Students will classify matter as either solids, liquids, or gases Students will observe the similarities and differences between solids, liquids, and gases Students will identify vocabulary terms Students will learn how to make play-dough in a supervised environment Students will identify the different states of matter used in the making of play- dough. South Carolina Standards: 2.1, 2-1.2, 2-1.4, 2-1.5, 2-4.1, 2-4.2, 2-4.3

4. IDENTIFYING MATTER: What is matter?- There are three types of matter we will be identifying: Matter is a physical substance or material SolidsLiquids Gases All matter takes up space; it is classified into one of these 3 categories depending on certain unique properties.

5. COMPARING SOLIDS AND LIQUIDS SOLIDS Tend to maintain their own shape; the shape is only changed if force is applied. They can be hard, soft, bouncy, or stretchy They have a definite volume- even if the shape changes, the volume remains the same LIQUIDS Assume the shape of their containers- they do not have their own specific shape They pour or flow from a higher point to a lower point They have a definite volume- even when changing containers, volume remains the same Remember: Volume is the amount of space that a substance or object occupies. Even if you rip up a piece of paper or pour water from one glass to another, the quantity or amount of that substance remains the same!

6. GASES Have no definite shape or volume They fill the area in which they are contained completely, taking up much more space than both liquids and gases. They are all around you, all the time! Most of the time, you can only see the container they are in, smell them, or feel them. Gases can be colorless, odorless, and virtually undetectable! Think About It! What are some gases you are in contact with everyday?

7. IDENTIFY: Solid Liquid Gas Observe: Look around the classroom, name some other items and identify them as either a solid, liquid, or a gas!

8. VOCABULARY REVIEW 1.______ tend to maintain their own shape, unless force is applied. 2.Liquids have do have _______ volume but no definite ______. 3.______ have no definite volume or shape. 4.A particular substance or material is called ________. 5.___________ is the amount of space that a substance occupies. 6.Pouring water from one container to another ________ change the volume. 7.The wind or helium in a balloon are examples of a _____. 8.Play-dough is an example of a______. *Bonus* Solids definite shape Gases matter Volume does not gas solid Think About It! Play-dough keeps it’s shape unless force is applied, it does not pour or flow, and it has a definite shape and volume. That is why it is a solid!
