On October 15th and 16th, we did a lab testing the different densities of certain liquids. My group and I worked really hard on this lab and got accurate results. Our experiment told us to make a procedure and a data table. There was five unknown liquid solutions and we had to figure out the really dense liquids and the not so dense liquids. To figure that we out, we had to find the mass and volume because mass/volume = density. Then we had to pour the liquids with the most density in the bottom up to the liquids with the least density. At the end of the experiment, if we did it right, the liquids would be all layered. My groups cup of liquids turned out really great. You are probably wondering how we measured the liquids. It's impossible to find the mass liquids without a container. So, what we did is measure the mass of the graduated cylinder (what we also measured the amount of liquid in) and then measured the mass of the graduated cylinder and the liquid together. After that, we subtracted the graduated cylinder to find the mass of only the liquid. When we were done with the experiment, we wrote out a procedure for step-by-step directions. Then we drew out the data table. As well as learning about the different types of densities, I also got to learn and practice more about lab safety and I got to have fun.
