**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.**Volume**• The amount of space an object takes up**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**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.**VIDEO INSTRUCTION**• Optional Video – Calculating Volume**THE SI UNIT KNOWN FOR MEASURING SOLIDS WITH A LARGER VOLUME**IS KNOWN AS THE… • Cubic meter (m³).**The formula for calculating the volume of a rectangular**object is: Volume = Length x Width x Height**THE SI UNIT KNOWN FOR MEASURING SOLIDS WITH A SMALLER VOLUME**IS KNOWN AS THE… • Cubic centimeter (cm³).**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**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** 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**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.**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!**UNIT 3: Metric System**TODAY’S AGENDA 10/10 FTF (Homework Out Please!)

What is the volume of the 2 cylinders on the right?**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). TODAY IN SCIENCE CLASS – FTF Metric Volume Lab Station 2 – Calculating volume Volume 2-Column Notes – Irregular Volume Metric Volume Lab Station 3 – Irregular Solids Homework: Volume of Irregular Solids Practice Worksheet SWBAT Explain the proper way to read the volume in a graduated cylinder; Accurately measure the volume of liquids using a graduated cylinder.**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. If you finish early see me for an extra challenge!**TICKET OUT**• Regular volume • What is the formula for calculating the volume of a rectangular solid object? • What metric unit is used for the volume of a small object? • A large rectangular object? • Liquid Volume • What is the name of the tool used the measure liquid volume? • What is the base unit for liquid? • What is the base unit for smaller amounts of liquid? • Define meniscus. • What is the proper way to read a meniscus?**UNIT 3: Metric System- Volume**TODAY’S AGENDA 10/16 FTF (working independently) • Come up with a way that we could we find the volume of this crazy looking rock? Be specific. 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.**VOLUME 2-COLUMN NOTES**WE ARE HERE**Volume**Volume of Irregular Solids**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**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**TEACHER DEMO - WATER DISPLACEMENT**• How can Mrs. Dean find the volume of this cool but very odd shaped mineral?**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.**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!
