Chapter 1 What is matter? 7th

Section One Matter is anything that has ___________and __________. (What is mass?) 2. Volume is the amount of _______ occupied by an object. (Is air matter? Does it take up space?) Teacher Demo. Cup/paper

True or False (A-D) If it is false, how could you make it a true statement? A. An object’s volume is the amount of space the object takes up. B. Things with volume can’t share the same space at the same time. C. When you measure a volume of water in a graduated cylinder, you read the top of the meniscus. D. A liquid’s volume is usually expressed in grams or milligrams.

3. Liquid volume is measured by using a ______________ ______________. The units of measure we use for liquid volume are the _________(L) and _____________(mL)

5. When we read the measurement, we read the ________ of the meniscus. 4. The surface of the liquid is not flat but curved in the cylinder. The curve is called the ______________. 5. When we read the measurement, we read the ________ of the meniscus. Correct: Viewing the meniscus at eye level Incorrect: viewing the meniscus from an angle

Reading a Graduated Cylinder 1. A graduated cylinder is used to find the volume of a liquid. The volume tells you how much space that liquid occupies.  2. The marks on the cylinder are called graduations. That is why the instrument is called the graduated cylinder. Each mark on this cylinder is worth one milliliter, a basic unit of measure for the volume of a liquid. A unit for larger volumes is the liter. 3. The graduations on a cylinder are not always worth the same. Before using the cylinder, you need to figure out what each graduation is worth. 4. When a liquid is put into a cylinder, the surface curves. This curve is called a meniscus. When reading the volume of a liquid, always read at the bottom of this curve while holding the surface at eye level.  5. The abbreviation for milliliter is mL. A capital L is used so that it is not confused with the number "1".  6. The lettered arrows on the diagram to the left point to volume measurements. Arrow "A" reads 48 mL. Write the answers to the other arrows on a piece of paper.
