Students were investigating filled cans of soda to test their density in water. Which conclusion can be made about the investigation?

Students were investigating the density of some substances. The students can make all of the following conclusions about their investigation EXCEPT...

• The sponge is more dense than oil

• The grape is more dense than water but less dense than syrup

• The screw is more dense than water and more dense than oil

• Water is less dense than syrup and more dense than oil

Which of the following items are likely MORE DENSE than water?

• Wood Pencil

• Plastic Ball

• Cork

• Penny

• Glass Bead

• Glass Marble and Plastic Ball

Which statement is correct?

• Corn syrup is denser than water.

• Water is denser than corn syrup.

• Water is less dense than oil.

Use the picture to select the correct statement.

• Oil is denser than water

• Pasta is less dense then crayon

Why do ice cubes float in a  glass of water?

• the ice cubes are more dense than the water
• the water is more dense than the ice cubes
• the water is more dense than the glass
• the ice is more dense than the glass

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball
