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.

Totally gross out your class with the eighth lesson in this series on food science. Explore the microscopic world of bacteria by taking swabs of different classroom objects and growing colonies in petri dishes. An engaging activity that...

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 are examples of student's science journal entries, a video of the...

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.

Trying to plan an engaging elementary science unit on natural resources? Conserve your energy! This five-part series of lessons and hands-on activities has exactly what you need to teach young scholars about the importance of conservation.

Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.
