In which figure(s) is the block accelerating?
What should be the

The %-Density Ratio
5. Estimate the percentage of the wood, ice, and Styrofoam block that is under water while those blocks are floating.
Remember: the density of water is 1.00 kg/L
6. Compare your estimations to the densities shown on the chart.
Place those densities in the chart above.
7. Create a formula to show how much of a floating object would be
Density of Wood
Density of Ice
Density of Styrofoam
% Wood under water
% Ice under water
% Styrofoam under water
