1. Turn to page #5 in your worktext. 1) Answer Question #1 (all parts of question) 2) Answer Question #2 The one on the left is a golf ball and the one on the right is a table tennis (ping pong) ball. The table tennis ball is orange in my book. On the “My Notes” section of your packet (after page 17) write the Essential Question for this lesson at the top. EQ: How does the composition of matter affect its density, volume, and mass? 1

2. 3) Lets look at Question #3 4) What is Matter? Page 6 Matter is anything that has mass and takes up space. Matter makes up the materials around you. Answer #5 and #6 on page 6 with your partner. 2

3. 3 What is mass? Page 7 Mass describes the amount of matter in an object. A gram is the unit of mass you will use most often in science class.

4. 4 How does mass differ from weight? Page 7 Weight is the measure of the gravitational force of an object. The greater that the mass of an object is, the greater the gravitational force on the object will be and the greater the objects weight will be. An objects mass does not change unless the amount of matter in an object changes.

5. Page #7 Question #7- Work with your table group to come up with a really good answer. Each person should write the answer in the space provided. Page 8 Visualize It- What is your answer to the question? Be sure to explain as clearly as you can!!!! How are mass and weight measured? Page 8 5

6. Quick Lab-Mass and Weight You are going to be working with your table groups to measure the mass and weight of 5 small objects. Under the Procedure Section on page 2, copy the list of objects for #1 and #2 in this order, one on each line. -Bolt -Battery -Wrench -Board -Bottle of Water 6

7. Demonstration on the use of Triple Beam Balance and Spring Scale. You will use the Triple Beam Balance to measure the mass of the object and record your measurement for #1 for all the objects. You will use the spring scale to measure the weight of the objects and record your measurement for #2 for all the objects. 7

8. Lab Rules: 1) Your group will measure the mass and the weight for each object just like Mr. Fisher did in his demonstration. 2) Each person will be required to use the Triple Beam Balance and the Spring Scale to make the measurement. 3) Make sure that you record the measurement for each object on the correct line. When you are done using the Triple Beam Balance, return the countermeasures back to the ZERO position. 8

9. Reporting your findings- we will now make a graph in order to report our findings. With the person sitting next to you, answer the questions for #3&#4. 9

10. Lab Sheet Answers #3&#4 #3- The graph is linear. This means as the mass of the objects increase, so does the weight. #4- The force of the spring scale pulling upward. 10

11. DO NOW- Study your lesson packet from pages 1-8 and be ready to answer some questions!!!! 11

12. Assessment – Describe the difference between mass and weight. Use an example (battery, bolt, board, bottle, or wrench) from the Quick Lab to provide details in your answer. 12

13. How is the amount of space occupied by matter measured? Page 9 The amount of space that an object takes up is know as the object’s volume. Answer #9 on page 9 Volume measures the amount of space that an object takes up or occupies. Think Outside the Box page 9 13

14. Measuring Space Page 10- Three ways to measure volume 1) Use a formula to find the volume of a well- defined shape. (V=lwh) – to find volume of a rectangle 2) Use water displacement to find the volume of irregular shaped objects like a rock. 3) For liquids, you can use a graduated cylinder. 14

15. Measuring Space Using a formula page 10 Homework- Page 11 What method would you use???? 15

16. DO NOW- Be ready to answer a question about volume !!!! 16

17. Measuring Space- Answer the following questions: A) What do we know? B) What is the formula used to find volume? C) Enter the values into the formula. D) What is the volume of the object? Length = 49 m width= 26 m height= 24 m 17

18. Measuring Space- Answer the following questions: A) What do we know? Length=49m, Width=26m, Height=24m B) Write the formula V=lwh C) Enter the values into the formula V=(49m)(26m)(24m) D) What is the volume of the object? V=30,576m 3 18

19. Think-Pair-Share Discuss the following question with your shoulder partner or someone at your table. How would you calculate the volume of a bolt? Can you use the same formula as you did when you were finding the volume of a locker?? Be prepared to share your response. 19

20. Using water Displacement- page 12 When an object is placed in water, the object pushes some of the water out of the way. This process, called displacement, can be used to measure the volume of an irregularly shaped solid object. *****1 mL of water is equal to 1 cm 3. Therefore, you can report the volume of the object in cubic centimeters. 20

21. Quick Lab – Finding Volume by Displacement We are going to use a bolt (an irregular shaped object)as our solid metal object. Predict what you think the volume of the bolt will be!! 1) Write 50 mL as the starting measurement in the graduated cylinder. 3) Write _______ for the measurement once the bolt in placed in the graduated cylinder. 21

22. With a partner, complete questions #4 and #5. You have three minutes. 22

23. DO NOW With the person sitting next to you, describe how you would measure the volume of: 1) A regular shaped object (Box) 2) An irregular shaped object (Bolt) Be prepared to discuss as a class!! 23

24. Packing It In What is density? Page 13 Density is a measure of the amount of mass in a given volume. Objects containing the same amount of mass can take up different amounts of space. With your table group, answer #13 and #14 24

25. DO NOW: Answer question #13 on page 13. THIS IS NOT A PARTNER ACTIVITY!! 25

26. 26

27. Homework- You Try It Problem #15 on page 14 27

28. 28

29. DO NOW 11-17-15 Please have your homework out and ready to be checked. 29

30. Lesson #1- Visual Summary : Page 16 #17- False- what is this a definition for? That’s correct- It is Volume #18- False- Which is greater? That’s correct- Mass is greater #19- True- why is it expressed in units of cm cube? #20- True- What happens to an object that is more dense? 30

31. Lesson #1 Review- Page 17 1) Volume 2) Matter 3) Mass 4) Density 5) Weight 6) Yes, Because air has mass and it takes up space. 7) Yes, mass is constant or does not change. The weight of an object depends on gravitational force. 31

32. 32

33. 12) You would use the measured mass and volume of the coin to calculate density. Then you would compare the known density of silver to the one that you calculated. 13) First find the volume of the truck bed. Remember V=lwh V= 2.5m x 1.5m x 1.0m= 3.75cm 3 7m 3 /3.75 cm 3 =1.866 The truck must make 2 Trips 33

34. Calculating Density You must write all instructions for both a regular and an irregular object. You must pretend that you do not know the mass or volume of the regular shaped or the irregular shaped object. You must show all of the mathematical steps with your instructions. 34
