This challenging worksheet has students answer multiple-choice questions, and fill in blanks to practice properties of matter skills.
It includes 9 questions across 2 sections for focused practice.

Properties of Matter
Part A: Multiple Choice
Circle the best answer for each question.
1. A student has two blocks that are exactly the same size. Block A has a mass of 30 g and Block B has a mass of 60 g. Which statement is correct?
A) Block A is denser because it weighs less and takes up less space.
B) Block B is denser because it has more mass packed into the same volume.
C) Both blocks have the same density because they are the same size.
D) Density cannot be compared unless both blocks are placed in water.
2. A layer of oil sits on top of water in a glass, and a marble rests at the bottom. What does this layering tell you about the densities?
A) Oil is densest, then water, then the marble is least dense.
B) The marble is densest, then water, then oil is least dense.
C) Water is densest because it is in the middle of the glass.
D) All three have the same density but different volumes.
3. A sealed balloon is placed in a freezer. After one hour the balloon is smaller. What best explains this change?
A) The gas particles escaped through tiny holes in the balloon material.
B) The gas particles lost energy and moved closer together, reducing the volume.
C) The gas changed into a liquid inside the balloon from the cold temperature.
D) The balloon material shrank because rubber gets smaller in cold air.
4. Ice floats on liquid water instead of sinking. Which explanation is scientifically accurate?
A) Ice is colder than water so cold things always rise to the top.
B) Ice has a lower density than liquid water because its molecules are arranged in a spread-out structure.
C) Ice floats because it is a solid and all solids float on their own liquids.
D) Ice floats because the air trapped inside the ice makes it lighter.
Part B: Fill in the Blank
Write the correct answer on each line.
1. When a substance is heated, its particles gain energy and move farther apart, which can lower its density.
2. A solid keeps its own shape because its particles are locked in fixed positions.
3. The temperature at which a solid turns into a liquid is called the melting point.
4. In a gas, particles move in all directions and fill the entire container.
5. Water is unusual because its solid form is less dense than its liquid form.
