Open the web browser and enter the link above into the address bar.

When the simulation page opens click "Run Now!"

Click the "Buoyancy Playground" tab at the top of the window.

Look in the yellow data box in the top left corner of the window. Record the mass (m), volume (V), and density () of the wood block.

In the middle of the screen there is a container of water. Record the volume of the water.

Drop the wood block into the water. Does the wood block float? Explain why or why not.

Place the block so that it is completely submerged in the water. Now what is the volume of the water? By how much did it change?

Make a statement about the volume of an object and the volume of liquid displaced.

Use the dropdown menu in the yellow data box to change the material of the block to Aluminum. Record the mass (m), volume (V), and density () of the aluminum block.

The white box with "0.00N" Printed on it is a scale, which measured the weight (in Newtons) of whatever is placed on it. What is the weight of the aluminum block on dry land?

Place the aluminum block in the water. Does it float? Explain why or why not.

Set the aluminum block on top of the scale. What is the weight of the aluminum block under water?

How does the weight of the aluminum block under water compare with the weight on dry land? Provide an explanation for why this is so.

What is the name of the force exerted on an object by a fluid in which it has been placed?
