Section: Describing Matter
matter: the ‘stuff’ that makes up everything in the universe. Matter has mass and volume
properties of matter: characteristics used to describe matter, ex:hardness, texture, color, whether it catches on fire
boiling point: the temperature at which a liquid boils – or turns into a gas
melting point: the temperature at which a solid melts – or turns into a liquid
Color- the property possessed by an object of producing different sensations on the eye as a result of the way the object reflects or emits light.
• Solubility (how much can be dissolved into a given
amount of water)
• Odor- A quality of something that is perceived by the sense of smell
• Hardness- is a measure of how resistant solid matter is to various kinds of permanent shape change when a compressive force is applied
• Density (mass/volume) -the density, or more precisely, the volumetric mass density, of a substance is its

￮￮ What is matter?
What is the difference between a physical and a chemical property
Students will be able to define matter, mass and weight and categorize things as matter or not matter.
Students will describe properties of matter and distinguish between those that are physical and those that are chemical.
Students will be able to identify characteristic properties of matter and explain their uses
Introduction: (15 min) Introduce the concept of matter by asking students what they think matter is. Get several answers and discuss with the class.
Present students with cards labeled with different words and ask them to decide which represent matter and which do not. Examples of matter could include desk, rock, air, milk, the sun, salt, and a person. Examples of non-matter could include ideas, thoughts, gravity, heat, and sound.
Give the students the definition of matter as anything with mass and that takes up space or has volume. Ask them to reassess their answers in step 2 and discuss again as a class or in small groups.
Body: (30 min)
Open the PPT presentation titled “ Describing a Matter ”
Go over the presentation . Define matter. Explain that everything around us is made up of matter; everything in the universe is made of the same tiny bits (particles), just that the particles are put together in different ways.
Use the analogy of Lego – Lego has a limited number of types of building blocks, but you can use them to make an infinite amount of different structures and objects
What is matter?
Develop a model to describe that matter is made of particles too small to be seen
Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
Make observations and measurements to identify materials based on their properties
Conduct an investigation to determine whether the mixing of two or more substancesProperties of Matter
Ask students to describe the properties of the samples identified as elements or compounds in the previous section and list the discussed properties for the class.
Discuss physical properties and define a physical property as a trait that can be observed without changing thecomposition of a substance. Examples include color, size, odor, and temperature.
To introduce chemical properties, perform a simple demonstration of a chemical reaction. Ask students to observe and note the physical properties of the substances before they react and after. Make note of the fact that the properties changed because a new substance was created. Define a chemical property as the ability of a substance to react to create a new substance.
Activity /Lab : Here are two options for a simple demonstration:
a. Add vinegar to baking soda in a flask or beaker.
b. Heat sugar in a beaker or flask over a hot plate until it caramelizes and then turns black.
Conclusion : (10min)
Reflection : (15 min)Checking for student understanding:
While students work in pairs, sorting the items, walk around, listen in on their discussions and ask probing questions to get a sense of students' understanding of matter.
The discussion of students' placement of items will reveal students' misconceptions and internal struggles about the concept of matter.
Demonstrate to students how they should fill worksheet after they will go through the video .
Make sure each student gets a worksheet . Have them write their names on their paper.
Make sure that students understand why it is important to fill the worksheet ( they will be graded).
Teacher should circulate around the room and assist students and making sure students are on task.
Make sure students clean up their work stations
