Building a boat for science class can be used to illustrate the ideas of displacement and propulsion. displacement is what makes a boat float. to float, the weight of the boat in the water (and the air in the boat) has to weigh the same as the water it pushes out of the way.. Build a boat grade 2 costs and time to build | glen-l boat plans, glen-l 15 – 15′ sloop. built by jim bradford – cost approximately $2500 and took about 7 months to build in 2010. built by casey sterbenz: here is the breakdown.. After building the boat, see how much weight it can hold. (pennies are a good option for older kids to use.) ways to build a boat create a boat building challenge. try this cork raft building challenge from kitchen counter chronicles. discover which materials make the best boats. science sparks shows you how..
Students research information about the boat's origins, the materials with which it is made, variations in design, and other details. find photographs that show the boat's interior and exterior construction.. Once they build their boats, they will float the boat in water and place pennies, one at a time, onto the boat until the boat sinks. the winner is the group who builds the boat with the best building cost to pennies floated ratio: total cost/number of pennies..
