1. Wake-up 1. List five pieces of lab equipment in the picture. 2.What are three pieces of lab equipment that can be used to measure volume?

2. Wake-up (Think!!) 1.What is the name of the “curve” that the eye is looking at? 1.What piece of lab equipment is shown to the right? 1.What is the measurement shown?

3. SWBAT Understand the various means of measuring for Biology. Apply measuring skills.

4. Measurements

5. Length The distance between two points.

6. Unit for Length Meter (m); Centimeter (cm); Millimeter (mm) Tool Ruler; Meter Stick

7. Mass The amount of matter (substances) within an object Who has the most matter, an elephant or a mouse? Who has the most mass?

8. Units for Mass Grams (g) Tool Electronic Balance

9. Volume The amount of space a substance occupies; gas, liquid or solid

10. Units for Volume Liter (L); Millimeters (mL) Tools Graduated cylinder (Preferred); Beaker; Flask

11. Meniscus Curved upper surface of a liquid in a tube Meniscus

13. How to read volume of a liquid What is wrong with the picture?

14. The graduated cylinder should be on a flat surface; Need to read volume at eye level

15. Read volume at the BOTTOM of the meniscus

16. Practice reading volume on a graduated cylinder Find the scale of the graduated cylinder. Read at the bottom of the meniscus. 8.45 mL

17. Practice reading volume on a graduated cylinder Find the scale of the graduated cylinder. Read at the bottom of the meniscus. 32.5 mL

18. Practice reading volume on a graduated cylinder Find the scale of the graduated cylinder. Read at the bottom of the meniscus. 33.5 mL

19. Practice reading volume on a graduated cylinder Draw in the water level for 11.4ml

20. Temperature Measure of the warmth or coldness of an object.

21. Units for Temperature Celsius (°C), Fahrenheit (°F); Kelvin (K) Tools Thermometer
