Today’s Agenda… 8-17 Bellringer: (Remember to write the question) What kind of units do we use to make measurements in science? Practice Measuring Length Notes on Measuring Volume (Foldable)

Measuring Volume Mrs. Bates’ 6th Grade Science Tuesday, August 17th Study Pack #3

Review We have began our study of measurement with length What unit do we use to measure length? What are some things we measure the length of in everyday life? How do we measure length?

Today’s Goals! I can calculate the volume of a regular object I can measure the volume of a liquid I can measure an irregular shaped object

Make your foldable! Volume of a Regular Shape Liquid Volume of an Irregular Shape 3

Volume Volume: the amount of space an object takes up Has 3 dimensions - length, width, height Unlike area!

Calculating Volume Regular shapes Use a ruler to measure each dimension (length, width, and height) It doesn’t matter which is which! Find volume using the correct formula V = l x w x h Units: cubic centimeter (cm3)

Try It! Let's practice more! Find the volume of a box is 10cm long, 15cm wide, and 20cm deep. Answer: 3000 cubic centimeters Let's practice more!

Volume of a Liquid Use a graduated cylinder Units: Milliliter (mL)

Volume of a Liquid Read the volume at the bottom of the meniscus The meniscus is the curved surface of the water Always read it at eye level

Volume of a Liquid Tips Know what the unnumbered marks represent Estimate if you are between 2 marks

Volume of Irregular Objects For example: a rock! When objects do not take on a regular shape or it is difficult to measure their dimensions we use a different method to find their volume, this method is called water displacement Use the method of water displacement

Volume of Irregular Objects Displacement is The amount of water an object replaces Equal to the object’s volume

Volume of Irregular Objects Steps 1.) Fill a graduated cylinder with a certain amount of water Not too much! But, it must be enough to cover the object you are going to measure! Volume of Irregular Objects 2.) Record the volume of the water in your data (starting volume)

Volume of Irregular Objects 3.) Carefully place the object in the graduated cylinder Be sure not to splash out any data or this will affect your results! 4.) Record the new volume in your data table (ending volume)

Volume of Irregular Objects 5.) Subtract the starting volume from the ending volume This is the volume of your object! You can write the volume in milliliters OR you can write it in cubic centimeters 1 milliliter = 1 cubic centimeter

Volume of Irregular Objects

Review How do we calculate the volume of a regular object like a box? What tool do we use to measure the volume of a liquid? What method do we use to measure the volume of an irregular object like a piece of oddly shaped metal?
