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.
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
Mass is the amount of matter (“stuff”) in an object.
Making Measurements in Science
The Metric System The scientific system of measurement
↗ Measurement. Biology ↗ ‘BIO-’ means life ↗ Ex: biography ↗ -ology means the study of ↗ Ex: radiology ↗ What do you think BIOLOGY means?
Notes – Measurement (7 th grade). International System of Units a way of measuring based on multiples of ten (10, 100, 1000…) abbreviated S.I. also called.
DOES THIS MAKE SENSE TO YOU? THE METRIC SYSTEM The metric system is a system of measurement that is based on the number ten It is often used in science.
