4. Body PartLength (cm) Height Head (around the ears) Head (from under the chin) Elbow to wrist Foot Wing span (finger tip to finger tip) Around your wrist Find an object in the room that measures exactly 40 cm. Object: Find an object in the room that measures exactly 15 cm. Object:

5. ObjectLength (cm) Pencil Paper Clip Note Card Band-Aid Playing Card Measure the longest side of each object

6. ObjectLength (cm) Width (cm) Height (cm) Volume (cm3) Mass (g) Kleenex Box Book

8. Two ways to calculate volume: 1. Length x Width x Height = Volume 2. Water Displacement using a graduated cylinder

9. When reading a graduated cylinder, always read from the bottom of the curve (meniscus) Steps: 1.Fill the cylinder about half way and read the amount. 2.Drop the object in the cylinder 3.Read the new water level 4.Subtract the old level from the new level. 5.You are done!

10. ObjectBeginning Water Level (mL) Ending Water Level (mL) Volume (mL)Mass (g) Marble Rubber Stopper

11. 1. What are two drawbacks to using the graduated cylinder to find volume? 2. How could you find the volume of an object that does not have a length, width, or height and does not fit in the graduated cylinder?
