Putting The Metric System All Together

Introduction: The purpose f this experiment is to show how all the basic units of length, volume and weight in the metric system are related to one another.

Background:

We know the metric system in many ways. From the meters to the liters the Metric System comes in many different ways. The basic units are in length, volume, and weight are also connected in ways that we don't know about . That's why this lab we measured everything from weight , volume, and the length of different objects.

Materials:

Balance, 100ml graduated cylinder, medicine dropper, plastic box, beaker, metric ruler.

Procedure:

The graduated cylinder was weighed. The weight was recorded under observations.

100ml of water was weighed inside the graduated cylinder.

The graduated cylinder and water was weighed. The weight was recorded.

The length of the plastic box was measured in centimeters.

The length was recorded.

The width of the plastic box was measured in centimeters. The width was recorded.

The height of the plastic box was measured in centimeters. The height was recorded.

The weight of the empty plastic box was recorded.

The box was filled with water.

The plastic box and water was weighed and recorded.

Observations:

The weight of the empty graduated cylinder is 127. 1 g.

The weight of the graduated cylinder and water is 231. 4 g.

The weight of the water alone is 104. 3 g.

The length of the plastic box is 30 cm.

The width of the plastic box is 15. 5 cm.

The height of the plastic box is 9 cm.

The weight of the empty plastic is 271 g.

The weight of the plastic box and water is > 610 g.

The weight of the water alone is > 339 g.

Questions:

The weight of 100ml of water is 104. 3 g.

The weight of 1 ml of water is 2. 225 g.

The volume of the plastic box is 4185 cm3.VOLUME= 30 x 15. 5 x 9

The weight of 1 cubic centimeter of water is 2. 225g.

How does the weight of the cubic centimeter of water compare with the weight of 1 ml of water? The weight compares by it having the same amount of units.
