Mai Lesson
Float Your Boat!
Science · 30 min · Ages 6-8 · Early elementary · You and your child together
This lesson challenges young learners to explore the science of buoyancy by designing and building simple boats. Through hands-on experimentation with everyday materials, children will discover what makes objects float or sink. It fosters critical thinking and problem-solving in a fun, interactive way.
What your child gets out of it
- Define buoyancy through observation and experimentation.
- Design and build a structure that floats on water.
- Explain how shape and weight distribution affect an object's ability to float.
What you need
- Aluminum Foil
- Small Objects — Small items like LEGO bricks, pebbles, or toys for the boats to carry. (or Marbles, Pennies, Plastic Animals)
- Water — Needed to fill the tub for testing boats.
- Tub — A container large enough for boats to float in. (or Large Bowl, Sink Basin)
