Part 2: Preliminary Activities A. Setup Go to the PhET tutorial page, titled Density, and run the simulation. B. Experiment Explore the simulator by experimenting with the settings and dropping the objects into the water. Part 3: Compare tab A. Choose same mass (should be 5.00 kg) Q1) What is the force of gravity (the weight (W)) on each block.Q2) What is the buoyancy force on each block: Red . Green Blue Yellow Q3) Predict which blocks will flow based on the block's weight and the buoyancy force: Red . Green Blue Yellow Q4) Were you correct in your predictions? D. Stacking Q1) What is the maximum buoyancy force of the least dense block? Q2) How much weight could it carry in the water? (maximum buoyancy force - its weight) Q3) Which blocks could you stack on top of this block? Q4) Stack these blocks on top of the least dense block in the water. Was your prediction correct
