PPT-Reading a Graduated Cylinder

Determine Scale What is each line worth Measure bottom of meniscus Get to eye level Scale Take two numbered lines that are next to each other and find their difference Divide that by the number of spaces between our two numbers. Lab. South Carolina Biology Standard. 2.8. Background. Pectinases. are enzymes that breakdown the polysaccharide pectin that is located primarily in the middle lamella of cell walls. Pectin compounds are widely distributed in plant tissues- especially in fruits. . Volume. Temperature. Mass. Reading the Meniscus. Always read volume from the bottom of the . meniscus. . The meniscus is the curved surface of a liquid in a narrow cylindrical container.. Try to avoid parallax errors.. Volume. – (def.) . the amount of space an object takes up. How could you find the. volume of a glass of. water? A penny?. Glass of water – measure out the volume using a graduated cylinder. Penny – use the “Water Displacement Method.
