Teach sink or float with a catchy science song for kids! Perfect for kindergarten & 1st grade, this STEM brain break uses movement, predictions, density & buoyancy to make learning fun in classroom, homeschool, and circle time. Try real-life mini experiments (rock vs. leaf, orange with/without peel, empty vs. full bottle) and help kids understand why some things sink and others float.

What kids learn:

• Sink vs. float (observable test)

• Density = “how packed the stuff is” (light-for-its-size floats, heavy-for-its-size sinks)

• Shape matters (same material, different shape can float)

• Making and checking predictions like real scientists

How to use:

Play once for fun, then again with props. Add motions: “PLOP” = crouch & drop hands, “BOAT” = arms out & gentle sway. Perfect as a brain break, warm-up, or quick science mini-lesson.

Materials for the demo: rock, leaf, rubber duck, coin, orange (with peel & peeled), plastic bottle (empty & filled).

Safety note: Always test with a grown-up and use safe, classroom-friendly items.
