Measurements are also important in science because they provide important specific information and help observers avoid bias. Measuring is comparing an object or process to a standard.

4. Measure: Length
Length is the distance between two points. Length is usually measured with rulers.
Examine the metric ruler diagramed below. Notice that the labeled units are in centimeters (cm). Small vertical lines separate each centimeter into 10 sections.

5. Measure: Liquid Volume
The volume of an object is the amount of space it takes up. You will often measure the volume of liquids using a graduated cylinder.
Always read a graduated cylinder at eye level. Also, water in a graduated cylinder has a curved surface called the meniscus. Read the volume at the bottom of the meniscus.

6. Measure: Temperature
Temperature is a measure of how hot or cold something is. In science, you will measure temperature with a Celsius thermometer like the one at the right. The correct unit for readings on this thermometer is °C

Today you will be creating a lab safety dos and don’t poster.
Sit quietly and brainstorm on a lab safety rule you can create a poster on

8. After Activity: You will be creating a do & don’t lab safety poster
You will do the following:
Choose a lab safety issue
You will make it neat and colorful
One side of your poster will show the wrong way to do something during a lab
One side of your poster will demonstrate the correct way to do it
Add a title to your poster
Put your full name and class period on
the back of the poster
