Sinking, Floating and Suspending Investigation (student handout)
We want to know why some objects float, others sink, and some will suspend in the water, neither sinking nor floating.
We have 3 blocks. All the blocks are the same size, 2cm on a side. One block is metal, one is wood, and the other is styrofoam.
Prediction 1:
Which objects, if any, will float,which will sink, and which will neither float nor sink (suspend)? Explain your reasoning.
Data Gathering 1:
Use the balance to measure the mass of each object.
Data Gathering 2:
Measure the size of the blocks and calculate the volume:
Calculation 1:
Calculate the density of each object:
Would you like to revise your prediction after calculating density? If not, why not? If yes, what is the revision and why do you want
to make it?
