A student is implementing an investigation of physical properties using samples of metals, nonmetals, and metalloids. She used a battery, wires, and a bulb to test if each of the samples will complete the circuit causing the bulb to light. Next, she shined a bright light on each of the samples.

Which physical properties is the student investigating?

• Streak and hardness

  
  

• Luster and conductivity

  
  

• Streak and conductivity
