Middle School Science Lessons

Objective: students will learn how to identify elements, compounds, and mixtures using molecular models

Materials:

• Google Slides (Public Link) – answers will pop up as you advance the slides.
  • For enrichment, in notes section, you can ask students if the mixtures are element mixtures, compound mixtures, or an element & compound mixture.
  • You can also ask students what types of bonds are shown in the diagrams: Ionic, Covalent, or Metallic.
• Sorting Cards: Students can sort cards into groups and discuss answers
  • Print out – 4 slides per page Element, Compound, or Mixture – Handout (1)
  • Print out – 2 slides per page Element, Compound, or Mixture – Handout (2)
• Handout – students can write answers onto the handout as you review each answer.
  • 6 slides per page Element, Compound, or Mixture – Handout (3)
• Elements, Compounds, and Mixtures Cut & Paste Activity (pdf) – Students will cut out and match atomic models with their formulas
• ECM Worksheet – additional practice on identification using molecular models (pdf)

Different ways to use this activity:

1. Vocabulary reinforcement
2. Students can review the slides independently as added practice and self check.
3. This can be a guided mini-lesson for a whole class to reinforce the concept.
4. Students can work in pairs to sort the cards into the 3 different groups, then discuss the answers as a class. Challenge – categorize the mixtures.
5. Give each student one of the larger cards and have them do the activity “Quiz, Quiz, Trade“
