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.

A simple and effective presentation could be helpful for your young scientists. Learners consider whether or not a piece of wood, glass, cork, brick, and ice will float or sink when placed in water. After the class has made their...

Learners 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...

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...

Learners develop their understanding of buoyancy and density related to sinking and floating. They investigate which objects sink and float through experimentation. They determine that different substances sink or float depending on...

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.

Will it sink or will it float? Learners predict the outcome as they drop random objects into a container of water. Then, they keep track of the results and record the data in a t-chart to draw a final conclusion.

Upper graders experiment with measurement. They estimate the length, volume, and weight of various objects, then rotate through stations making predictions concerning measurements and then testing their predictions.

Use the scientific method to experiment with an egg. Your class can examine buoyancy and density by finding how many spoons of salt are needed to float an egg. They can predict, experiment, record data, and analyze results.

Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
