Language Friendly Pedagogy

Ask students whether they can add new vocabulary to their Concept Detective document. You may print this or make a copy  for each student on programs like Google Classroom. Students will be encouraged to use this document each class to identify new words, consider writing meaning or finding meanings with the help of peers, teachers and/ or parents.

Examples of concepts to add for this unit include:

  • ecological pyramids
  • limiting factors
  • energy
  • food chain
  • producers, (primary, secondary, tertiary)
  • consumers
