1.1: 1.2 1.3: 1.4: 1.5: 1.6: 1. Experimental Validity of Archimedes' Principle Change the block so that it is aluminum. Calculate the volume of your block in m3 and record the result in your notebook. Using the digital scale that is on land in the PhET, measure and record the force of gravity of the block. Calculate and record the block's density (in kg/m3). Compare it to the stated density in the top left corner (make sure you convert it to SI units). Assuming the block will be completely submerged when placed in the central pool of water, use the volume of block and knowing the density of water calculate the buoyant force on the block, F3. Place the block in the central pool of water on the submerged scale in the PhET, measure and record the force of gravity of the block. Record this measurement. Place the aluminum block back on the land and alter its volume to 7.5 L. Repeat steps 1.1 to 1.4 with this new value for volume. Place the aluminum block back on the land and alter its volume to 10 L. Repeat steps 1.1 to 1.4 with this new value for volume. Record the results of your previous steps in a table with the following columns. Column 1 (V) is the volume of the block, column 2 (W0) is the weight of the block outside of the fluid, column 3 (W1) is the weight of the block inside of the fluid, and column 4 (F3) is the buoyant force on the block when it is submerged in the fluid
