Plastics Balance Scale and Graduated Cylinder Builds

For this build, you will need a 25 inch PVC pipe, Kite string, Plastic cups, a Clothes hanger, and a Cardboard box. For the graduated cylinder, you will need your pinky, a piece of paper, a sharpie, and a plastic cup.

Balance scale step 1-2: Get a Cardboard box, Long nail, 25 inch PVC pipe, Clothes hanger, String, and a plastic cup. Next Drill a hole in the PVC pipe and put the nail through it.

Balance Scale step 3-4: After you have done steps 1-2 cut a hole in the cardboard box and make SURE that the PVC fits. Next, put the PVC in the box's hole and tape the PVC to secure it down.

Balance Scale steps 5-6: After you have completed steps 1-4 then you can complete these steps. For this step, you will take a clothes hanger and you will need to cut a piece of kite string that is 8-15 inches long. And tie it to the clothes hanger.

Balance Scale Step's 7-8: Once you have done steps 1-6 you can do these steps. After step 6 put the clothes hanger on the long nail. And now you have a completed balance scale!!!

Graduated Cylinder Build Steps 1-2: First, you must get all the supplies. The supplies needed are a Plastic cup, a Piece of paper the size of a child's hand. Sharpie, Tape, and your pinky finger.

Graduated Cylinder Build Steps 3-4: Then you will cut a piece of paper from the lip of the cup to the bottom of the cup. You will need to use your pinky to mark 6 spots on the paper using the marker.

Graduated Cylinder Build Steps 5-6: After you have done steps 1-4 you can do these steps. After marking the paper tape it to the cup. And walla you have finished the graduated cylinder.

I used the Graduated Cylinder to measure density. The way I used this is by placing an object in the water and seeing how high the water would rise. The first object that I used was a hand sanitizer bottle which rose 11 tick marks. The other object that I used was a Pez dispenser. After collecting all the data the hand sanitizer had more mass and density. The Pez dispenser had more density. The next experiment that I conducted was comparing a Kindel styilis and a rubber finger puppet. The styilis had more mass and density and mass. They both shared volume moving 3 tck marks.

I plan on using these tools for comparing density. And I will also use the balance scale to
