2. This tool is used to measure the VOLUME of a liquid. The proper way to read this tool is at EYE LEVEL at the bottom of the MENISCUS, which is the curved surface of the liquid.

3. MENISCUS

4. 1) 7 mL 2) 38 mL3) 33 mL4) 20 mL What is the volume of the rock? 5) 20 mL

5. Metric rulers are used to measure length, width, and height. The LARGE numbers on the ruler are CENTIMETERS. The small lines between the centimeter marks are called MILLIMETERS. There are TEN (10) millimeters in a centimeter.

6. What do the SMALL lines between the numbered marks represent? CENTIMETERS MILLIMETERS How many millimeters in a one (1) centimeter? 10 mm

7. 5.1 centimeters (5.1 cm) 5.1 cm X 10 = 51 millimeters (51 mm)

8. Thermometers are used to measure TEMPERATURE. Since scientists use the METRIC SYSTEM, they use thermometers that measure degrees Celsius rather than degrees Fahrenheit.

9. 17 degrees C

10. An electronic balance is used to measure the MASS of an object. It is a more PRECISE tool than a triple beam balance because it can record mass to the hundreth of a GRAM.

11. To the nearest WHOLE number: 45 grams (45 g) To the nearest tenth: 45.2 grams (45.2 g)
