LEGO Boat Engineering Challenge for Kids

Did you know the largest ship in the world (as of writing this post) is called the Prelude? It is the size of four soccer fields and can hold 19,000 twenty-foot shipping containers.

How do large ships like the Prelude float?

Explore the concept of buoyancy and put your engineering skills to the test as you construct your own LEGO boat.

How many pennies can your boat hold before it sinks?

STEAM Challenge: How many pennies can your LEGO boat hold?

Materials:

LEGO Bricks

Container of Water

Pennies

Timer (optional)

Step 1: Sketch and design your LEGO boat. Once you are satisfied with the design start building your boat.

Step 2: Test your boat in the water. Does it float? If needed go back and re-design your boat.

Step 3: Predict how many pennies you think your boat will hold before it starts to sink. Slowly add the pennies (one at a time) to your boat.

The Science Behind It:

Buoyancy is the upward force that keeps an object afloat.  An object will float when it’s buoyancy is greater than the object’s weight.

    This is great! I’m fairly clueless (still) about STEM, but this is a simple activity we can try!

      I view STEM as exploring and experimenting with the scientific, engineer and design process. It is all about asking questions and exploring curiosity! Let us know how it goes!
