This Friday is LEGO® Fun Friday!  The challenge for this week is to build a LEGO® boat that actually floats (and that doesn’t involve a pre-made LEGO® boat as the base).

Some pointers:

  • Don’t tell your kids any of these pointers at first – let them experiment and see what they come up with!
  • Aidan’s boat in the picture does not float.  Too top heavy.  Even when he removed the top part of the boat, he had several “leaks” to seal up by overlapping LEGO® bricks.  This boat design now floats, although it takes on a little bit of water.  I think it’s impossible to seal up every crack.
  • For younger builders, a raft type design works well.
  • If a boat sits up too high in the water, it will be very tippy.  We were remembering that ballast was important for boats in the book “Carry On, Mr. Bowditch.”
  • Build boats that are just for looks if it gets too frustrating!
Our boats are still a work in progress, and the boys are having fun experimenting with different designs!  I’m thinking I’ll through in a writing assignment and have Aidan write an essay describing what works and doesn’t work – homeschool moms always try to multitask! Ha!

Come back Friday to link up your post.  We can’t wait to see what boat designs your kids come up with!  The challenge is meant to be a starting point for your kids, but feel free to link up any kid-generated LEGO® designs or LEGO® learning activities.

    Love this idea, I'll have to try it with my boys!

      Every boat my students built floats. Maybe I was doing something wrong but it seemed to be an overly easy challenge.

        I'm sure you weren't doing something wrong! How old are your students? My boys were 9, 6, and 3 when we did this challenge, and they thought it was a lot of fun! I would definitely recommend testing out any challenge before doing it with a class to see how it will match up with their ability level.
