Measuring in Science: Metric Magic

The video tutorial explains how different units of measurement are interchangeable, focusing on the metric system. It uses water as an example to illustrate that one milliliter of water occupies a volume of one cubic centimeter and has a mass of one gram. The concept of density is introduced, showing how objects with different densities behave in water. The tutorial concludes by highlighting the convenience of the metric system in comparing mass, volume, and density.

What is the volume of one milliliter of water in the metric system?

• One cubic inch

• One cubic meter

• One cubic centimeter

• One liter

How much does one milliliter of water weigh?

• One kilogram

• One gram

• Ten grams

• One milligram

What is the density of water in the metric system?

• One gram per milliliter

• One gram per cubic centimeter

• One gram per cubic meter

• One gram per liter

Why do objects with a density greater than one gram per cubic centimeter sink in water?

• They are less dense than water

• They are heavier than water

• They have less mass than water

• They have more volume than water

Which of the following objects is likely to float in water?

• A marble

• A glass bead

• A piece of Styrofoam

• A metal coin
