ANALYZE IT

  • After your group has investigated and recorded various physical properties, including the masses and volumes of the unknown substances, be prepared to discuss the impact of your observations and measurements on the Investigation.
  • Complete the Analysis Questions in your SDR and be prepared to discuss them as a class.

 

  • Do any of the substances share similar properties? 
  • Compare the physical properties of the different samples. Can you determine which samples are elements and which are compounds? If so, how? If not, why? 
  • Is it possible to determine whether any of the unknown substances contain the same elements? If so, how? If not, why? 
  • Can you determine whether any of the unknown substances contain the same elements? If so, how? If not, why? 
  • What other types of information may be helpful in determining the identity of the substances and elemental composition of the substances? 

GET FOCUSED

Complete the Focus Questions in your SDR and be prepared to discuss them as a class.

  • Can you tell the difference between an element and a compound by measuring mass and volume? Explain your answer. 
  • Can you determine the identity of an unknown substance by observing its mass and volume? Explain your answer.
