5. 8. <ul><li>A meniscus is the curve of the surface of the water in a graduated cylinder. </li></ul><ul><li>Water &quot;sticks&quot; to the walls of the graduated cylinder, but only on the sides and not the middle.  </li></ul><ul><li>When you look at the surface, the water level is not straight – it’s curved like a smile.  </li></ul>
6. 9. <ul><li>Measurement should be at the BOTTOM of the meniscus. </li></ul><ul><li>Read the meniscus at eye level in to get an accurate reading.  read the meniscus at eye level. </li></ul>Read the volume here
7. 10. How to Measure LENGTH
8. 11. <ul><li>Most metric rulers have lines indicating centimeters and millimeters. </li></ul><ul><li>The centimeter lines are the longer, numbered lines. </li></ul><ul><li>The shorter lines are millimeter lines. </li></ul><ul><li>When you use a metric ruler, line up the 0-centimeter mark with the end of the object being measured. </li></ul>
