Aiden and Noah are comparing two objects. "The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• mass

• volume

• marble

• foam ball

Answer explanation

Aiden and Noah state that the balls have the same mass but the foam ball has more volume. Since density is mass divided by volume, the marble must have more density than the foam ball.

Look at the picture and match the following:

• A

• Density

  1.05g/ml

• B

• Density

  0.89 g/ml

• C

• Density 1.25g/ml

Sam and Rylan are examining two materials. These two objects have the same ​​ (a)  

• size

• density

• volume

• mass

Answer explanation

The balls have the same mass, meaning they weigh the same. However, the foam ball has more volume, indicating it takes up more space. Since density is mass divided by volume, the foam ball has more density.

"The balls have the same ​ (a)   , but the foam ball has more ​ (b)   .

So, the ​ (c)   has more density.

• volume

• marble
