Classification of Matter Activity – students read 3 short and engaging informational text passages about an element, a compound, and a mixture, then complete a CER for each section using evidence from the text for each one.

Includes PRINT and GOOGLE versions!

The CERs focus on evidence of the substance being an element, a compound, or a mixture. Each of the 3 sections (1 page each) includes:

  • Short, engaging text passage with background information and properties
  • Claims-Evidence-Reasoning question
  • Follow up questions

Engaging Passage Topics Include:

  • Multi-million dollar rose gold eggs
  • Gallium pranks
  • The hazards of dihydrogen monoxide

We find this a helpful practice for standardized tests because it requires using background knowledge and information from text to arrive at an answer.
