Buoyancy: Who Sank the Boat?
Students examine whether objects will sink or float. In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

Who Sank the Boat?
Fifth graders experiment with student-made aluminum boats to test for buoyancy. They design a boat and determine how many marbles it takes to sink it while recording their data in a spreadsheet. They design a graph using the data and...

Sink or Float?
Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

Watercraft
Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

Paddle Power
Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...
Curated OER
Sink or Float?
Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.
Curated OER
Sink or Float?
Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...
Curated OER
Water and Ice
Learners investigate the states of matter. In this physics activity, students use water and ice to demonstrate the characteristics of a solid and liquid. Learners record their observations as the state of the water changes.

Ship Building Trip
Students travel to a ship building plant to see how they are built. They enter into discussion and writing about the task of the building. This activity is multiple intelligence in design and valuable because of the real life exposure.
