2. KEY VOCABULARY cubic centimeters (cm3) is a commonly used unit to measure volume and corresponds to the volume of a cube that measures 1 cm × 1 cm × 1 cm. liter (L) Metric unit of volume. One liter is approximately 1.1 quarts. metric system The measuring system used by scientists and most countries other than the United States and United Kingdom. milliliter (mL) Metric unit of volume. One mL is 1/1000 of a liter and is equal to one cubic centimeter. qualitative Description, observation or analysis of a substance based on its qualities. quantitative Description, observation or analysis of a substance based on measurements. volume The amount of space that an object or substance occupies.

3. In your science notebook, copy the following chart

5. Materials

7. volume of a cube or bar is l x w x h, where l = length, w = width, h=height Make a Note Volume for a cylinder is πr²h, where r = radius and h= height. Make a Note Light colored bar V = L x W x H V = 5cm x 1.2cm x 1.2cm V = Light colored cylinder V = πr²h V = 3.14 x 0.6²cm x 5cm V = 7.2cm³ 5.7cm³

9. Before you measured the volumes, you made a prediction of the volumes from least to greatest. Go back in your notebook and compare what you predicted to the actual data. Where they the same? Explain.
