Scientists use a wide variety of tools to study the world around them, and because all sciences involve measurement, there are certain tools of measurement used by all scientists. Students were divided into six groups. Each group used the materials necessary for this activity and performed the following procedure:
Observations and conclusions were recorded on the following table.
Students discovered that the color of the test tubes should be in the same order as the rainbow: A–red, B–orange, C–yellow, D–green, E–blue, F–violet. Also, all the test tubes should contain 11 mL of water. How did we do? Page created October 23, 2002 View Science Standards |
Sixth Grade Science
To find the volume of a liquid, scientists use a graduated cylinder. A graduated cylinder is marked off in 1-milliliter segments. Each line on a graduated cylinder is 1 milliliter. To measure the volume of a liquid, pour the liquid into a graduated cylinder. You will notice that the top surface of the liquid is curved. To determine the volume of the liquid, read the milliliter marking at the bottom of the curve. This curve is called the meniscus.
The sixth grade applied their knowledge of measuring liquid volume with a graduated cylinder. The purpose of this activity was (1) To develop skill in measuring with a graduated cylinder and (2) To use the metric system in measuring volume.
The materials used in this activity were as follows:
