Kids learn the concepts of physics

through building, testing, and


improving model boats. You show
them how to start and they
generate creative ideas, solve
problems, and learn in the process.

Aluminum foil boats – 12”


square, formed into a boat.
Test to see how many
pennies or nails it can hold.

Gravity-powered boat –
styrene or paper cup
mounted on 1 or 2 styrene
or paper plates. Straw(s)
inserted into the base of the
cup. Pour water into the cup
to make the boat move. Test
to see what you can do to
make the boat go fast.

Boat hulls – paper milk or


juice cartons cut in half
lengthwise. Cut along one
side (flat-bottom hull) or
along an edge (V-hull) –
each carton makes 2 boats.

Add sails – paper, plastic


bags, or cloth mounted on
¼” dowel

Balloon-powered – use 12”


round balloons and a straw
(milk shake straw works
well) or piece of vinyl
tubing. Test to see how far it
travels.

Rubber band powered –


make paddle wheels by
dove-tailing two rectangles
of milk carton. Use craft
sticks or dowels to hold the
paddle – either as a stern
wheel boat or side wheel
boat.

Stern wheeler

Rubber band powered boat


using “nose hook” propeller
from an airplane model.

Electric boat – toy motors


powered by 9-volt battery,
connected with alligator clip
leads. Air propeller, water
propeller, or paddles

Electric belt drive. Or


substitute a gear drive for
the paddle boat.

Make a propeller out of


aluminum foil and power it
with a 1.5 volt battery.

Pump boat using small


water pump powered by a
battery.

Make an ocean with a tarp


and four walls that won’t
fall down.

Make a carrot submarine.


Power it with baking
powder. The wood dowel
provides buoyancy and
keeps the sub upright.
