Save drink boxes and the straw that they come with. If you want to make the ships fancier, cover the drink boxes with contact paper that looks like wood. Make a tiny hole in the top of the drink box and stick the straw into the hole to make a mast. Cut out a flag for each child. Fold it on the dotted line, place the straw in the fold and tape in place.
Cut a piece of plastic milk jug or a piece of plastic disposable cup and tape it onto the straw for a sail. Let the kids float the ships in a wading pool or water table.
Have the kids take a drinking straw and blow into the sail. The ship will move.
Itís a great science project that teaches about wind.
