 Hi, my name is Kenneth Gamble, 4-H Foundation Regional 4-H Agent in Morgan and Lawrence County. Today I'm going to be talking to you about buoyancy and the materials we're going to need to do this project, we're going to need aluminum foil ruler or measuring tape and this is a 12 by 12 piece of aluminum foil and what we're going to do, we're going to cut it in quarters and cutting it in quarters, we'll end up with four six by six pieces of foil. And what we're going to do is do a project that comes from the 4-H National Jump Draw Robotics curriculum that's called Penny's in a Boat and with Penny's in a Boat the object is to design a boat out of the six by six piece of foil. Once you design your boat, you're going to put it in a bowl of water and it can be as long as it fits the foil you're fine, it doesn't have to be anything large, you can use your sink if you don't want to use a bowl, just something that can hold the foil and then what you're going to do is design your boat and in designing your boat you can just make up anything you like and then you're going to place it in the water, once you place it in the water you're going to add your coins which we're using in a boat and you're just going to place them on there and see how many pennies that you can put on your boat before it sinks as you add your pennies. Also, time and see how long it takes before your boat sinks. You can do this with your family, you can do it with your friends, it can even be a family competition, a friendly competition. See who boat looks the best, who boat lasts the longest with the pennies, just a fun activity that you can do at home. Again, you can have four pieces, you can try this one with piece one, then you have a second one, you can have a second design, a third design and with your fourth one why don't you try it with a different coin maybe nickels, quarters or dimes. Also, you can look at changing the type of foil you have, you can use a heavy weight or a lightweight piece of foil so there's a lot of different things that you can do. You maybe want to change from bowl to dry wax paper, just whatever. Just have fun doing it and make it a fun family event. Pennies on a boat. Thank you.
