1. 09/01/2016 Convert the following: • 1000 mg = _______ g • 1 L = _______ mL • 14 km = _______ m • 109 g = _______ kg • 160 cm = _______ mm • 250 m = _______ km Compare using <, >, or =. 7. 56 cm or 6 m 8. 7 g or 698 mg

2. Volume A measurement of the amount of space something takes up.

3. From atoms… to planets If it exists in nature, it takes up space…

4. Measuring Volume There are two types of volume measurements: • Cubical objects… • Non-cubical objects… Cubical objects have parallel edges that meet at right angles. Non-cubical objects have non-parallel edges and/or curves .

5. Measuring Volume • The volume of cubical objects is measured with a ruler. Measure the length (L), width (W) and height (H) of the object. • L x W = the area of the Base (B). B x H = the Volume of the object.

6. Measuring Volume • After measuring L, W and H, multiply the 3 numbers together. The product is the volume of the object. The unit of measure would be mm3, cm3, m3, etc. • Cubic Centimeters (cm x cm x cm = cm3)

7. Measuring Volume of Non-cubical ObjectsakaThe Displacement Method Volume is a measurement of how much space matter takes up.

8. Measuring Liquid Volume with a Graduated Cylinder • Place the graduated cylinder on a flat surface. • Never hold it up to your face. • Get your eyes at level of the liquid in the cylinder so your sight line skims the top of the liquid.

9. Check to see if there is a meniscus present. A meniscus can make the liquid level appear higher than it is. • Look at the bottom of the meniscus to get an accurate measurement.

10. You can accurately read a graduated cylinder to .5 mL. • What is the volume shown?

11. You can accurately read a graduated cylinder to .5 mL. • What is the volume shown? 37.5 mL

12. Volume By Displacement • Fill the graduated cylinder at least halfway with water. • Record the volume of the water. • Drop the object into the water without splashing.

13. Record the volume of the water and the object together. • Subtract the volume of the water from the volume of the water and object. This is the volume of the object. • Remember- Convert liquid volume units (ml) to solid volume units (cm3)

14. Today’s Directions • Find the volume of the rectangle by measuring the length, width, and height with a ruler and then multiplying. • Find the volume of the rectangle by using the displacement method. • Find the volume of the cylinder solids by using the displacement method. • Don’t forget the correct units of measure.
