![]() Can you make a small boat with twigs? A giant boat with big sticks? Try more and fewer sticks to make a wider or skinnier raft. What difference does it make?Įxperiment with size for your boat construction as well. STEM experiment: Try a stick boat with a sail and without a sail. We used some extra hot glue around the base of the sail to make it stick. But it is a bit clunky and can be tricky to attach to the boat. It makes the boat look more like a boat, and less like a raft. Glue the two stick-halves together so the the sail is in the middle.Glue the bottom of the sail to one of the stick-halves.For a fabric triangle: tie both ends to another stick to make a sail. For a paper triangle: glue it to another stick to make a sail. ![]() If you're going to make a sail, don't glue the two halves together yet. We glued 2 sticks together, and then another 3 together. Try more and fewer straws to make a wider or skinnier raft. Try full size straws to make a bigger raft. How many can you fit on before it capsizes.Įxperiment with size for your boat construction as well. What difference does it make?Īlso, try loading your straw boat with cargo (like small coins). STEM experiment: Try a straw boat with a sail and without a sail. But when a paper sail gets wet, it makes the boat much more likely to capsize. Glue the two halves together so the the popsicle stick sail is in the middle.Glue the popsicle stick to one half of your boat.Glue the paper triangle to the popsicle stick to make the sail.We glued 2 sets of 4 together before gluing both halves to each other in step 5. We used 4 straws cut in half, giving us 8 half-straws for our raft. popsicle stick and paper triangle for a sail (optional).We used paper straws to make this boat, and glued them together in a flat raft design. Are there other ways you can construct your boat? Can you make it into other shapes? Which method is the most durable? Least likely to capsize? Holds the most cargo? For the stick and the straw boats, we just glued our elements together in a straightforward raft. How many can you add to your boat before it capsizes? Which type of boat can hold the most cargo? (Note: do this in a kiddie pool or a bathtub, not a stream.) Use pennies or nickles (or anything else you can find that can get wet) and stack them on or in your boat. We bet once you start you’ll want to make more and more. If you haven’t tried it before we really would recommend giving it a go. We’ve made a short video to show you how to make a paper boat that really floats. See if you can add cargo to your boat. One of our favourite activities that we revisit again and again is boat making. ![]() Which type is most durable? We made 5 different types of boats, using sticks, straws (the paper kind), paper and cardstock, corks, and tin foil. Making and floating boats is already a STEM activity, since you have to engineer your boat and figure out how to put it together and make it float.īut to add some other STEM elements and turn your boat making activity into more of a science experiment, you can do a few things: Turning Your Boat Making into a STEM Activity ![]()
