Introduction: VOLUMENATOR

My name is Mollie and for my science class we had to make our own balance scale and graduated cylinder and this is how you do it! I started off my project with a plain plastic water bottle for my graduated cylinder. After I got the water bottle I cut the top off, so it would be easier to put the liquid/solid in the bottle. I then put some labels on the bottle using mL. I tested it by filling the cup half way. I dropped a lemon into the water and it went up at least by five mL. For my balance scale I first collected all my items needed like a hanger, red ribbon, two cans, and electrical tape. After finding all my items, I then tied my ribbon onto the hanger and secured it with electrical tape. After, I tied the ribbon onto the two cans.The two cans hang from each side of the hanger connected to the ribbon. To make it evenly balance out I tied another ribbon to the opposite side of where the ribbon originally was. Those were my steps on how to make a balance scale and a graduated cylinder!!!

Step 1: Supplies Needed to Make a Balance Scale

Up top shown is the supplies and materials I used to build the balance scale. For the balance scale I used (two cans, ribbon, old shoe tie, pink hanger, and electrical tape. I also have the sketch that I drew before I built my design up top.

I had a plan for my design but then it didn't work, so I changed some parts of my design. This is why you should always have a back up plan.First, I researched "DIY Balance Scales." https://images.search.yahoo.com/yhs/search;_ylt=AwrCwLVhfNdfmEYABwAPxQt.;_ylu=Y29sbwNiZjEEcG9zAzEEdnRpZAMEc2VjA3BpdnM-?p=diy+balance+scle&type=b.

Step 2: Building the Balance Scale

At first you will need to collect all of your materials and items. Next, I cut the tops of my two cans and taped each end of my long ribbon to opposite sides of each can. Then I attached the center of each ribbon onto each end of the hanger

Step 3: Testing the Balance Scale

I tested the balance scale by adding dental floss and a lindt ball on the other side. These items weren't equally balanced out because the lindt ball has more mass inside. I also collected to other items that I know weigh differently. I got a lemon and my T.V remote. Can you guess which one weighed more? You guessed it, the lemon weighed more because it has more mass than the remote.

Step 4: Supplies Needed for Graduated Cylinder

You only need two objects to build this homemade graduated cylinder. The two items you will need is a plastic water bottle and labels. You don't have to use labels but, it seemed easy to write the mL then stick it on to the bottle.

Step 5: Building the Graduated Cylinder

In order to build this graduated cylinder you will need adult supervision. In order to drop items into the graduated cylinder and to test it, you will have to cut the top off evenly. So, that is the first thing you have to do. The next step is to write down your mL on labels then stick it onto the bottle. After you do that you want to test it.

Step 6: Testing the Graduated Cylinder

I tested my graduated cylinder by filling the bottle up to 15 mL then dropping a lemon into the bottle. Since the lemon has so much mass, the water in the bottle went up to at least 20 mL.

Step 7: Using the Tools to Compare the Density of Objects

Density is how much matter is in a given volume. To determine what the density of an object is you divide the mass by its volume. In order of density (least to greatest): empty shampoo bottle (low mass, largest volume, lowest density), floss dispenser (low mass,low volume, low density), Lindt chocolate ball (medium mass,low volume, medium density), golf ball (high mass, low volume, high density), competition medal (highest mass, low volume, highest density). First, I used the balance scale to compare each object to each other to determine which had more mass comparatively. Then I used the graduated cylinder to compare each object to determine which displaced the most water, giving me a comparative volume. The objects with the lower mass and higher volumes were the least dense, the objects with the most mass and the least volume were the most dense. I ranked them according to what I observed.

Step 8: Conclusion

The balance scale and the graduated cylinder will come in handy for my future projects because in my science class we usually work on measuring mass, density and volume. A tip that I learned while designing my balance scale and graduated cylinder is to always take your time and never rush!

    Nice work on this! I can't wait to see what you build next.
