Sink or Float

Investigate which items float and which ones sink using this resource.  Learners participate in an activity in which they investigate this phenomena. Then they describe the experimental process, and learn how to display their results.

Ahoy mate! Grab your telescope, adjust your eye patch, get your pirate hat ready and explore what sinks or floats in an engaging activity about liquids and solids. Young sailors learn about different properties and characteristics of...

Natalie Morales performs a simple experiment to show what the word float means by placing a pumpkin in water. This video could be used as an introduction to a science experiment on buoyancy. It would be fun to have your class experiment...

Students often classify objects by size and shape. Now they will look more at the properties of objects such as hardness, flexibility, and texture. Included in this lesson plan are examples of student's science journal entries, a video...

Students make and test predictions about sinking and floating, and classify objects according to whether they 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...

Students investigate whether different objects sink or float in water using the Scientific Method. They listen to the book "Christopher Columbus" by Stephen Krensky, identify the steps of the Scientific Method, conduct the sink or float...

Learners investigate which objects sink and which ones float. Learners engage in an experiment, make predictions, and record results on a graphic organizer. This is a comprehensive and easy to follow resource.
