  1. UNIT 3: Metric System TODAY’S AGENDA 10/9 FTF - Think – Pair – Share (You and your buddy will each need 1 piece of paper for today’s FTF!) Think: (Alone) Think about what volume is. Write down a definition or draw a picture to explain it in your own words. Pair: Talk with your buddy and together come up with an improved definition. Brain storm: On your table are several objects. Come up with a way that you could measure the volume of these objects (draw a picture, make a list, or write a few sentences). Share what you came up with with the class! TODAY IN SCIENCE CLASS – Review FTF Volume 2-Column Notes “Building Blocks” Partner Activity Metric Olympics Lab – Station 1 Ticket to Leave Homework: Practicing Volume Worksheet – Even numbers only! SWBAT Identify the formula for volume of a regular object and correctly calculate the volume of 5 regular shaped objects.

  2. VOLUME 2-COLUMN NOTES

  3. Volume

  4. Volume • The amount of space an object takes up

  5. How can the volume of a solid object such as a shoebox be measured? • To measure a solid objects that are regular shaped, a formula for volume can be applied • To measure a rectangular object such as a shoebox, multiply the object’s length, width, and height • L x W x H

  6. CALCULATING VOLUMEPARTNER BUILDING BLOCK ACTIVITY • With your buddy, please complete the following activity and answer questions 1 – 4 (use 1 piece of paper) • Calculate the volume of one small cube. • Build an object that is 3 cm3 x 3 cm3 x 2 cm3. Describe what you built on your paper. • Calculate the volume by applying the formula L x W x H. What is your answer? • Count the number of cm3 cubes you used & write it down. • What relationship do you see between the number of cubes you counted and the answer you got when you applied the L x W x H formula? • Optional Challenge: Build an object with a volume of 24cm3. Draw or describe what it looks like, how many cubes were used, and what was the L, W & H.

  7. VIDEO INSTRUCTION • Optional Video – Calculating Volume

  8. THE SI UNIT KNOWN FOR MEASURING SOLIDS WITH A LARGER VOLUME IS KNOWN AS THE… • Cubic meter (m³).

  9. The formula for calculating the volume of a rectangular object is: Volume = Length x Width x Height

  10. THE SI UNIT KNOWN FOR MEASURING SOLIDS WITH A SMALLER VOLUME IS KNOWN AS THE… • Cubic centimeter (cm³).

  11. WHY IS THE UNIT CM³ USED WHEN CALCULATING THE VOLUME OF A RECTANGULAR OBJECT? • When multiplying the object’s length, width and height, the cm units are also multiplied cm x cm x cm = cm³

  12. GIVE IT A TRY!SUPPOSE A CEREAL BOX IS 10 CENTIMETERS LONG, 4 CENTIMETERS WIDE, AND 20 CENTIMETERS HIGH. WHAT WOULD BE THE VOLUME OF THE BOX? Volume = Length x Width x Height Volume = 10 cm x 4 cm x 20 cm Volume = 800 cm³

  13.  Reading Checkpoint (page 51): What is a cubic meter? • The SI unit used to measure solids with a larger volume • A cubic meter is equal to the volume of a cube that measures 1 meter on each side

  14. METRIC STATION LAB • Write your name on the lab packet! • We will be doing 1 station a day until we finish our lesson on volume. • Keep lab packet in the classroom box until all stations are complete.

  15. METRIC OLYMPIC LAB – STATION 1 • Answer Pre-Lab Questions 1 - 3 • Procedure • Choose one object. Record the name or number on dta table. • Estimate the volume of the object in cm3. • Record estimate. • Find the actual volume using L x W x H. Measure accurately and show your math! • Record actual volume on data table. • Repeat steps 1 – 5 for remaining objects. If you finish early see me for an extra challenge!

  18. UNIT 3: Metric System TODAY’S AGENDA 10/11 FTF (Homework Out Please!) What is the name of this tool? What is it used for? What is the base unit for measuring small amounts of liquid? TODAY IN SCIENCE CLASS – Review Homework Volume 2-Column Notes – Liquid Volume (Meniscus – B, C & D; all A) Metric Volume Lab Station 2 – Liquid Volume WILT Homework: SWBAT Name the tool used to calculate the volume of liquids and accurately measure the volume of 3 different liquids.

  19. VOLUME 2-COLUMN NOTES

  20. Volume Volume of Liquids

  21. WHEN MEASURING THE VOLUME OF A LIQUID, SCIENTISTS USE A UNIT KNOWN AS THE… • Liter (L).

  22. To measure the volume of smaller liquids, the _________ is used. • Milliliter (mL)

  23. THE INSTRUMENT USED TO MEASURE THE VOLUME OF LIQUIDS IS CALLED THE… • Graduated cylinder.

  24. THIS INSTRUMENT HAS MARKINGS THAT ARE IN INCREMENTS OF… • 1 milliliter (mL)

  25. Meniscus • The curve in the top surface of water in the graduated cylinder

  26. Figure 4: Observing - What is the proper way to read a meniscus? • Read the milliliter marking at the bottom of the curve

  27. HOW TO READ A GRADUATED CYLINDER - VIDEO What is the value of each line on these cylinders? What is the volume of the 2 cylinders on the right?

  28. UNIT 3: Metric System- Volume TODAY’S AGENDA 10/15 FTF (working independently) Do You Remember from Last Week? • What is the name of the tool used to measure the volume of a liquid? • Define meniscus. • Describe how to properly read the meniscus (hint: 2 important rules).

  29. METRIC OLYMPIC LAB – STATION 2 • Answer Pre-Lab Questions 4 & 5 • Procedure • Fill a small graduated cylinder with 10 ml of water • Using an eye dropper, count the number of drops it takes to raise the water to 11 ml. Record the number in the data table. • Starting now at 11 ml, count the drops it takes to raise the volume to 12 ml. Record in data table, • Starting now at 12 ml, count the drops it takes to raise the volume to 13 ml. Record, • Calculate the average. Record in data table.

TODAY IN SCIENCE CLASS – FTF review Volume 2-Column Notes – Irregular Volume Metric Volume Lab Station 3 – Irregular Solids Hand out study guides/quiz review Homework: Study for quiz SWBAT List the steps involved in the water displacement method; Accurately measure the volume of 3 irregular shaped objects using a graduated cylinder.

  32. VOLUME 2-COLUMN NOTES WE ARE HERE

  33. Volume Volume of Irregular Solids

  34. How is the volume of an irregular solid such as a rock measured? • To measure the volume of an irregular solid, immerse the object in water, and measure how much the water level rises • This is called the water displacement method

  35. How does the water displacement method work? • Record the volume of water in the graduated cylinder • Carefully place the irregular solid into the water. Record the volume of the water plus the object • Subtract the volume of the water alone from the volume of the water plus the object • Video on Displacement

  36. TEACHER DEMO - WATER DISPLACEMENT • How can Mrs. Dean find the volume of this cool but very odd shaped mineral?

  37. METRIC OLYMPIC LAB – STATION 2 • Answer pre lab questions 6 & 7 before beginning • Procedure • Pick up one irregular shaped object. Record the name in the data table. • Place some amount of water in the cylinder (at a level higher than the size of the object). • Carefully read the meniscus and record volume to the nearest mL on data table. • Slide the object carefully into the cylinder and record the volume on data table. • Subtract the final volume from the initial value and you will have the volume of the object. Record on data table. • Pour water back into the beaker and retrieve the object. • Repeat with remaining objects.

  38. TICKET OUT • Describe in at least 3 sentences the process of calculating the volume of an object using the water displacement method (you can list steps if you prefer). • Calculate the volume of the object to the right. Remember, no naked numbers!
