2.1: 2.2: 2.3: 2.4 2.5 2.6 2.7 In this part of the lab, you will use the wood block. Calculate the volume of your block in m3 and record the result in your notebook. Using the digital scale that is on land on 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). Place the block in the central pool of water. Visually estimate how much of the block is submerged in the water (do the best that you can). Express your result as a percentage (9.9. "70% of the block is submerged"). How much did the volume of the pool of water change? Find the ratio of change in volume of the pool of water with volume of the wood block. Express this ratio as a percentage (e.g. "if the ratio is 0.65 then 65% is your percentage"). How does this value compare to your visual estimation you found in 2.2? Using the volume of displaced pool of water and knowing the density of water calculate the buoyant force on the wood. Compare this value to the force of gravity that you found in 2.1. On the bottom, change the Fluid Density of the pool of liquid from Water to Honey and repeat steps 2.2 through 2.4. Is the buoyant force the same whether you used water or honey as the fluid? In the upper right hand corner, change the wood block to an ice block and repeat steps 2.1 through 2.5. Did the density of the block of wood and ice have to be less than the density of water in order to float (i.e. not be completely submerged)? Lead has a much greater density than water. How does a boat or ship carrying hundreds of pounds of lead float while that same lead would sink to the bottom of the ocean if dumped overboard
