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?

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?

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

Measurements

Length The distance between two points.

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

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

Units for Mass Grams (g) Tool Electronic Balance

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

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

Meniscus Curved upper surface of a liquid in a tube Meniscus

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

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

Read volume at the BOTTOM of the meniscus

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

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

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

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

Temperature Measure of the warmth or coldness of an object.

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