Description

This lesson uses the Floating Ink Experiment to teach students the core physics concepts of fluid dynamics. This 45–60-minute lesson has proven successful with students from Grade 1 through Grade 4 and offers complete differentiation to meet the needs of all learners. Students will use dry-erase markers to investigate the role of Density and Surface Tension in flotation. They will analyze why some materials are pushed up by water and how invisible forces affect their everyday world.


What’s Included:

This resource is designed to be comprehensive and immediately ready for classroom use:

  • Two Differentiated Worksheet Sets: All activity pages are included in a reproducible (printable) format.
    • Set 1: Easy Level (K-2): Focuses on simple vocabulary and direct concepts.
    • Set 2: Advanced Level (3-6): Focuses on scientific terms, critical thinking, and application.
  • Teacher's Guide Section: Includes a scientific breakdown of the experiment, a full materials list, and essential Troubleshooting Notes to ensure successful execution.
  • Vocabulary Flashcards: Two complete, differentiated sets (Easy/Advanced) in both Color and Black & White for cost-effective printing and vocabulary reinforcement.


Lesson Focus:

  • Core Physics Concepts: Density and Buoyancy (Understanding the water's upward push).
  • Invisible Forces: Analyzing Adhesion (ink to plate) and Surface Tension (the water's "skin").
  • Application: Identifying Non-Porous vs. Porous materials.


This Project is Ideal for:

  • Floating & Sinking science units.
  • Forces and Motion explorations.
  • Introduction to Density and Fluid Dynamics.
  • Differentiated instruction in mixed-grade classrooms.


Why Teachers Love This Resource

  • Combines an engaging experiment with scientific documentation.
  • Includes everything needed for lesson prep, execution, and student assessment.
  • Differentiated worksheets and flashcards ensure appropriate challenge for all skill levels.
  • Encourages critical thinking and the use of scientific vocabulary.

Great value
I’m not a science teacher, but I was able to confidently teach this lesson—and my students loved the floating ink challenge! The materials were simple and easy to find, using things I already had on hand. Everything was clearly explained, and the kids were totally engaged. I’d definitely use Pocket of STEM resources again!
