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...

I'm sure you've heard that there are something like 20 tablespoons of sugar in a can of regular soda. It seems unbelievable, doesn't it? This demonstration really does show how much sugar is present in a can of soda. First, Spangler...

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...

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.

Young scholars 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...

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...

Young scholars make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

Special needs students explore why certain objects sink or float. They will make predictions on what objects will sink or float. Students conduct an experiment using a large bowl of water and several objects and test their predictions....

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.
