Buoyancy and Density Activity Directions: Go to the following website to use an interactive simulation to work with buoyancy and density: Density Simulation https://phet.colorado.edu/en/simulations/density Lab Part 1 1. Click over to the Compare and begin the lab. 2. Start by selecting Same Mass. One by one, place the blocks in the water and calculate the buoyant force on each block by calculating the amount of water displaced. Take the density of water to be 1.000*10^3 kg/m^3. (this density has four significant figures) 3. In the table below, insert the correct units next to the name of the quantity in the first row. 4. Show here your calculation of mass of water displaced and buoyant force for at least one block. Block Color Mass of Volume of Mass of Buoyant Block Water Water Force Displaced Displaced Lab Part 2 1. Now change the setting to Same Volume. 2. Using the masses displayed and the volumes given, calculate the density of each block and compare it to the density of water given above. Notice which block sinks and which is partially submerged. 3. List the behavior of each block (sink or partially submerged in the table below) 4. Rank them in order of density and see if there is a relationship between their density and the amount of volume that is submerged in water. Explain your results in terms of Archimedes' principle. 5. Once again, insert the units next to the quantity label in the first row. Block Mass Volume Density Behavior Lab Part 3 1. Now select the Same Density setting and place all of the blocks in the water. 2. What do you observe? Do they all float at the same level or do they float at different levels? 3. Given that the blocks all have different masses and different volumes, does it seem that density is dependent on how big or massive an object is or does it only depend on the ratio of the mass and the volume? Explain clearly
