Measuring and comparing matter

Physics - Grade 4-5

Instructions: Read each problem carefully. Show your work in the space provided. Include units in your answers.
  1. 1
    An apple balanced against metal masses on a pan balance.

    A student places an apple on a balance. The balance shows 150 grams. What property of matter is being measured?

  2. 2
    A rectangular eraser shown as a grid of unit cubes with dimension arrows.

    A rectangular eraser is 5 centimeters long, 2 centimeters wide, and 1 centimeter tall. What is its volume?

  3. 3
    A rock with a balance scale and graduated cylinder for measuring mass and volume.

    A rock has a mass of 60 grams and a volume of 20 milliliters. What is the density of the rock?

  4. 4
    Two same-size balls, one with sparse particles and one with tightly packed particles.

    Two balls are the same size. Ball A has a mass of 40 grams. Ball B has a mass of 80 grams. Which ball is denser, and why?

  5. 5
    Two measuring cups show water rising after a small toy is dropped in.

    A measuring cup contains 30 milliliters of water. After a small toy is dropped in, the water level rises to 45 milliliters. What is the volume of the toy?

  6. 6
    A balance scale tips downward on the side with a notebook compared with a pencil case.

    Which has more mass: a 25 gram pencil case or a 40 gram notebook? Explain your answer.

  7. 7
    A cube made of unit cubes shown with a balance scale.

    A cube has a mass of 24 grams and a volume of 8 cubic centimeters. What is its density?

  8. 8
    A feather and marble in equal-size boxes, with the balance tipped toward the marble.

    A feather and a marble both fit inside the same small box. The marble has more mass. Which object has greater density if they take up about the same amount of space?

  9. 9
    A shell being placed into a graduated cylinder to measure volume by water displacement.

    A student wants to measure the volume of an oddly shaped shell. Which tool and method should the student use?

  10. 10
    Two equal-size cubes show sparse particles in one and tightly packed particles in the other.

    An object has a density of 1 gram per milliliter. Another object has a density of 5 grams per milliliter. Which object has more matter packed into the same amount of space?

  11. 11
    A small block and a larger block shown with equal balancing masses.

    A block has a mass of 50 grams and a volume of 10 cubic centimeters. A second block has a mass of 50 grams and a volume of 25 cubic centimeters. Which block is denser?

  12. 12

    Fill in the missing word: Volume is the amount of space an object takes up. Mass is the amount of matter in an object. Density compares an object's mass to its ____.

  13. 13
    A bolt raises the water level in a graduated cylinder.

    A small metal bolt has a mass of 36 grams. It is placed in a graduated cylinder, and the water level rises from 18 milliliters to 24 milliliters. What is the density of the bolt?

  14. 14
    A same-size sponge and stone, with the balance tipped toward the stone.

    A sponge and a stone have the same volume. The sponge has a mass of 10 grams, and the stone has a mass of 100 grams. Explain which one has the greater density.

  15. 15
    A large porous foam block and a small metal cube, with the scale tipping toward the metal cube.

    A student writes, 'A large object is always denser than a small object.' Explain why this statement is not always true.
