  • Students will be able to describe how solids can change.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about solids. Show them different objects and ask them to identify which are solids. Introduce the video.
  • Video Viewing (5 mins)
    Play the 'States of Matter - Solids' video from Bow Tie Guy and Wife. Encourage students to pay attention to the examples of solids and how they are described.
  • Discussion (10 mins)
    After the video, discuss what the students learned. Review the definition of a solid, and the different types of solids. Ask them to name more examples of solids that they see every day.
  • Activity: Solid Scavenger Hunt (15 mins)
    Have students go on a 'Solid Scavenger Hunt' in the classroom or schoolyard. They should find and list as many different solids as they can in a set amount of time. Discuss their findings afterwards.
  • Conclusion (5 mins)
    Review the key concepts of the lesson. Ask students what they learned about solids. Preview the next lesson on liquids or gases.

Interactive Exercises

  • Sorting Solids
    Provide a collection of objects (e.g., rock, cotton ball, water in a bag, air in a balloon). Have students sort them into groups of solids and non-solids, explaining their reasoning.
