Building a boat can be a great engineering challenge to try either on your own or in a group. You can make it out of anything that you want or can find at home. Recycled materials can be a good place to start. You can make your boat big or small and use whatever you like to build it, but before you start you might want to test to see if the things you want to use are going to float...
When you put something in the water there are two forces acting on it. The weight of it forces it down while the force of the water forces it up. If the weight is less than or equal to the force of the water then the object will float. It the weight is more than the force of the water the object will sink. If you want to know more about why objects float or sink have a look at the BBC Bitesize Website.
So have a look and see what materials you can find. I have added an example of a boat made from cardboard and silver foil but use your imagination to see what you can do...
