SC15.5.4

Investigate whether the mixing of two or more substances results in new substances (e.g., mixing of baking soda and vinegar resulting in the formation of a new substance, gas; mixing of sand and water resulting in no new substance being formed).

Cause and Effect

Knowledge

Students know:
  • When two or more different substances are mixed, a new substance with different properties may be formed.

Skills

Students are able to:
  • From a given investigation plan, describe the phenomenon under investigation, including the mixing of two or more substances.
  • Identify the purpose of the investigation.
  • Describe the evidence from data that will be collected, including quantitative and qualitative properties of the substances to be mixed and the resulting substances.
  • Collaboratively plan an investigation and describe the data to be collected, including: how quantitative and qualitative properties of the two or more substances to be mixed will be determined and measured, number of trials for the investigation, how variables will be controlled to ensure a fair test.
  • Collect necessary data.

Understanding

Students understand that:
  • Cause and effect relationships are identified and used to explain changes like those that occur when two or more substances are mixed together.

Vocabulary

  • variables
  • states of matter
  • properties of matter
  • chemical change
  • physical change
  • evidence
  • temperature
