Finding Volume The Water Displacement Method
Volume of sample = final water level − initial water level Students may be confused that the unit for volume in the graduated cylinder is milliliters mL when in the previous lesson students calculated volume in cubic centimeters cm 3 Explain to students that 1 ml is the same as 1 cm 3.
