Volume Laboratory Experiment Part 1- Measuring the volume of a liquid Volume of a liquid: Instructions: 1. Use an appropriate sized graduated cylinder. 2. Fill a beaker up with water 3. Slowly pour the water into the graduated cylinder going drop by drop when you are close to the volume needed. 4. Ensure you read the volume from the bottom of the meniscus. What is the volume of the liquid? _________ What are the units for volume of a liquid? ________ Activity: Work with a partner to measure out the following volumes of water using a 100 ml graduated cylinder. Each partner will measure the volume indicated and then will check if the their partners measurement is correct by looking to see if the meniscus is in the correct position. If the measurement is done correctly you can put a check mark in the column beside the measurement. Volume to be measured 1 44 ml 2 95 ml 3 75 ml 4 12 ml Check mark if it is correct! Part 2- Measuring the volume of a solid. Method 1: Volume using a formula Instructions: 1. Measure the length, width and height of the object 2. Use the formula V= l x w x h to calculate the volume 3. Make sure to include units Units: ________________ Measuring Equipment: __________________ Example calculation: When we use this calculation: _________________________________________________________________________________________________ _________________________________________________________________________________________________ Method 2: Volume using a graduated cylinder Instructions : 1. 2. 3. 4. 5. Fill a graduated cylinder with water Record the initial volume Place the item in the graduated Record the final volume Use the formula VFinal –Vinitial to find the change in volume. 6. Convert the units from ml to cm3 Initial Volume (Vi) Final Volume (V2) Volume of the object (V2-V1) What are the units for the volume of the object?_____ When would we use this method? _________________________________________________________________________________________________ _________________________________________________________________________________________________ Method #3: Volume using an overflow container Instructions: 1. Place a beaker or a graduated cylinder under the overflow spout. 2. Fill the overflow container with water until it starts to pour out of the spout. 3. Empty the water from the container used to catch the water 4. Place the item into the overflow container and catch any water that drips out. 5. Be patient and wait for the last drops. 6. Pour the liquid from the beaker into a graduated cylinder and record the volume 7. Change the units from ml to cm3 Let’s Practice!
