In this Cyberchase Media Gallery, explore key concepts about liquid volume, including standard units of liquid measure and how to convert between them. In the accompanying classroom activity, students create a complete conversion chart from the smallest measure (a fluid ounce) to our largest measure (a gallon). They use equations to prove that their conversions are accurate and learn to recognize mathematical relationships or patterns between the different measurements. This resource is part of the Math at the Core: Middle School Collection.
