Lesson Description

This lesson uses a fun science experiment to teach 2nd graders about the properties of solids and liquids, and connects these concepts to the importance of trusting in God's word as a solid foundation.

Key Concepts

  • Solids have a definite shape and volume.
  • Liquids have a definite volume but take the shape of their container.
  • Mixing solids and liquids can create a substance with unique properties.
  • God's word is a reliable foundation like a solid rock.

Learning Objectives

  • Students will be able to identify examples of solids and liquids.
  • Students will be able to describe the properties of solids and liquids.
  • Students will be able to relate the concept of a solid foundation to the importance of trusting in God's word.
  • Students will be able to discuss the temporary nature of worldly possessions compared to the permanence of God's love.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they already know about solids and liquids. Show examples of solids and liquids (e.g., a rock, water, a toy, juice). Briefly define solids and liquids based on their properties (shape, volume).
  • Video Viewing (5 mins)
    Watch the 'Kids Talk - Science Series (Solids & Liquids)' video from Lincoln Baptist Online (https://www.youtube.com/watch?v=Vrqr76UNG-A). Encourage students to pay attention to the examples of solids and liquids that Miriam uses.
  • Experiment Demonstration & Discussion (10 mins)
    Recreate the cornstarch and water experiment from the video. Mix cornstarch (solid) and water (liquid) to create the oobleck. Allow students to observe and touch the mixture. Discuss: Is it a solid or a liquid? Why? How does it behave? (It acts like both!).
  • Bible Connection & Application (10 mins)
    Relate the experiment to the Bible story of building a house on rock vs. sand. Discuss: What is a solid foundation? What happens when we build our lives on things that aren't solid (like toys or popularity)? How is God's word like a solid rock? Refer to Matthew 7:24-27 as presented in the video.
  • Wrap-up & Reflection (5 mins)
    Review the key concepts of solids and liquids. Ask students to share ways they can build their lives on God's solid foundation. Close with a short prayer, thanking God for His word and asking for help to trust in Him.

Interactive Exercises

  • Solid or Liquid Sort
    Provide students with pictures or objects. Have them sort the pictures/objects into two categories: Solids and Liquids.
  • Building Blocks Foundation
    Have students use building blocks to build two structures: one on a solid surface (desk) and one on a less stable surface (a stack of books or a wobbly table). Discuss which foundation is stronger and why.

Discussion Questions

  • What are some other examples of solids and liquids you see every day?
  • Why is it important to have a solid foundation, like a rock?
  • What are some things people might build their lives on that are like sand?
  • How can we trust in God's word like it's a solid rock?

Skills Developed

  • Observation
  • Classification
  • Critical Thinking
  • Connection Making (science to faith)
