CAPT Lab

Introduction: The purpose of our experiment was to determine, by using mass, volume, and density, if all the chips in the container labeled A were the same element and all the chips in the container labeled B were all the same element. We also had to figure out if the chips in container A and B were the same element or if the elements differed according to the information we collected. We also had to determine if the cylinders consisted of the same material. Finally, we had to figure out how all the chips and cylinders were related to each other by what each object consisted of.

Variables: Independent: Volume Dependent: Mass Controlled: Density, Shape, and Temperature

Relation to Earth Science: This experiment related to earth science because it consisted of elements and how they are portrayed in other objects. This falls under Geology because geology is the study of the origin, history, and the structure of earth. Elements are apart of everyday life, even if we don’t realize it. Elements make up almost everything in the world, so this experiment falls perfectly under Geology.

Procedure: Materials:
50 of metal chips labeled - A
50 metal chips labeled - B
15 metal cylinders labeled 1-15
50 ml graduated cylinder
25 ml graduated cylinder
Triple beam balance
Metric ruler
Vernier caliper
Water
Calculator
Plastic container

Instructions:
Measure cylinders (1, 5, 7, 10 & 15) using the Vernier Caliper and measure to the nearest hundredth (Immediately convert the length into centimeters using the conversion factor)
Measure the diameter (straight line passing through the center of a body or figure) of the cylinders to the nearest hundredth (Immediately convert the diameter into centimeters using the conversion factor)
Find the radius by dividing the diameter by two.
Measure the cylinders on the triple beam balance and measure to the nearest tenth
In order to find the volume, use the volume formula (volume=πr2h) and then take the results and use the density formula (density=mass/volume) to find the density of the five selected cylinders.
Measure the chips labeled A (10, 20, 30, 40, & 50) using the triple beam balance and place the chips in a plastic container (provided for you).
Repeat step 6, with the chips labeled B (10, 20, 30, 40, & 50)
Take the 25 ml cylinder and fill it with water up to the 12 ml tally mark and pour 10 chips labeled A in during. Measure the amount of water that was added above 12 ml.
Pour the water out, take the chips out and dry them. Take 10 more chips relatively the same size and add them to the chips used previously.
Pour the same amount of water (12 ml) into the 25 ml cylinder and pour the next 20 chips that you put aside in step 9, into the cylinder. Record the amount of water that has risen above the 12 ml mark.
Repeat step 9 until you reach 50 chips.
Repeat steps 8-11 with the chips labeled B. (Instead of using the 25 ml cylinder, use the 50 ml cylinder and when doing step 8 fill the cylinder with 25 ml of water, instead of 12 ml).
