Most to all experiments and labs require some form of measurements. Because there are many various kinds of measurements, it is important to be aware of the different factors of each measurement involved with the current lab experiment. It is also important to have a general understanding of them because they will need to be used in calculations for the lab. Precision and accuracy will be used most in this lab. A knowledge of the following†¦show more content†¦When calculating measurements in experiments, it is vital that one will accurately measure the quantities that are given to you. This goal can be easily accomplished by testing the following hypothesis: If a rock is dropped into a graduated cylinder that if full of water, the rock will push aside an amount of water that is equal to its volume. This will cause the water level to rise. The volume of the rock will be equal to the volume of the water with the rock in it, minus the volume of the water without the rock included. Materials Used Water Rocks Graduated Cylinders Beakers Pipets Balance Procedure --- Part A --- Reading and recording volume from a graduated cylinder 1. Find the graduated cylinder that already contains water. 2. Read and record the maximum capacity of volume for your specified cylinder. 3. Read and record the amount of water in the cylinder. Don t forget to look at the bottom of the meniscus for your recording. Procedure --- Part B --- Filling graduated cylinders with specified amounts of liquid 1. Find an empty graduated cylinder 2. Using the beaker containing clear water, fill your graduated cylinder to the specified amount below 3. If your cylinder is a 250 mL cylinder, then fill it with 100 mL 4. If your cylinder is smaller, then fill it with 50 mL 5. Next, use a pipet to add 2 more mL to your graduated cylinder.
