Properties of Matter Structure and Properties of Matter

To begin with… Discuss with your group how these things are alike and how they are different. List them and be ready to share than information with the class.

What is matter? We will read page 38 together. What is the two requirements for something to have matter? It must have mass and take up space Is there anything in the universe that you can see that does not have matter? No

Volume What is volume then? It is the amount of space taken up, or occupied, by an object. Can things with volume share the same space at the same time? No

How do we measure volume? You read page 39. Then answer the following questions. 1. What do you use to measure the volume of a liquid? 2. Where do you look to measure the volume of liquids? 3. Is it easier to see the meniscus in a wide or narrow beaker? Answers: 1. graduated cylinder 2.bottom of the meniscus 3. narrow

Next Draw figure 2 from page 39 to your notebook. Also include the information in the writing below it.

Volume of Regular Shaped Objects We will read the paragraph at the top of p The volume of any solid object is expressed how? 2. What is the formula for finding the volume of a regularly shaped cube? Answers: 1. cubic unit 2. Volume = length X width X height

Volume of an Irregularly Shaped Object Read the last paragraph on page 40 to yourself Describe how you measure the volume of an irregular shaped object in your own words. Fill a graduate cylinder with some water. Record the level that it reaches. Then drop the object carefully in the water. Record the level it reaches. Subtract the 1 st recording from the 2 nd recording. That is the volume

Find the volume!!! 1. square that is 5m in length, 2m wide, and 3m high 2. rectangle that is 10m in length, 1m wide, and 4m high All the following are placed in 10 ml of water. The readings below are after the item is placed in the graduated cylinder 3. Die 15 ml 4. Rock 21 ml 5. Ring 17 ml

Mass and Weight Read pages to yourself. Copy down information to your notebook that you can use to help yourself identify mass, weight, and inertia. You will have 10 minutes to do this.

Now in groups Close your books, you may only have your notebooks out Make a chart showing the differences between mass and weight. Be ready to give at lease one difference between them.

Differences between mass and weight MassWeight Mass is the measure of the amount of matter in an object Weight is a measure of the gravitational force of an object Mass is always constant for an object no matter where the object is located in the universe Weight varies depending on where the object is in relation to the Earth (or any large body in the universe) Mass is shown by using a balance Weight is shown using a spring scale Mass is expressed in kilograms, grams, and milligrams Weight is expressed in Newtons

Inertia Thinking back, do you remember what inertia is? It is the tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object Why is mass and inertia related? The more mass something has, the more inertia something has
