CONTENT STANDARD: Physical Science
CONTENT TOPIC: Matter
CONCEPT: The properties of matter can be identified and measured.
CONTENT OBJECTIVE: 5D2.00 To understand the properties of matter
INSTRUCTIONAL OBJECTIVES: The learner will:
TN COMPONENT OF SCIENCE: Process Of Science
BENCHMARK: Things change in steady, repetitive or irregular ways. Tables, charts, and graphs are effective ways to show quantitative values and relationships.
1.5b Non-mathematical language may be used to interpret the relationships presented in mathematical form.
BENCHMARK: Written and verbal presentations are used to explain information presented in charts, graphs, and tables.
1.5c Information should be related to prior knowledge.
BENCHMARK:The process of making predictions, drawing inferences, and developing conclusions is based upon an individual's prior learning and understanding of scientific principles.
(Divide the students into groups of three. Give each group two balloons, two empty containers of approximately equal size, and two equal size containers of water. Instruct them to place the balloons into the empty containers before filling them with water.) What is in each balloon? (water) Are the two balloons shaped the same? (No, they took the shape of the container.) Can we say that liquids take up space and take the shape of the container? (Yes) How do these characteristics compare to those of a gas? (They are the same.) (The experiments are not designed to show that a gas takes up uniformly all the space it is allowed, while a liquid in an oversize container would not be able to adjust to take up all the space.
Now take the marbles and place them into the clear plastic cup. As you look through the sides of the glass, do you see space between the marbles? (Yes) Can we say that solids take up space, but don't take the shape of the container? (Yes)
(Fill a tall, slender bottle full of water. Have students predict what will happen to the shape of the liquid when poured into a smaller bottle. They need to write predictions in journals. Do similar processes with solids and gases.)
