WHY DO SOME THINGS FLOAT WHILE OTHERS SINK

Steal cubes sink, but steal ships float. Lesson explores the density of solids as well as the density of water in determining what will sink and what will float. A hands-on group activity helps pupils see that weight and volume are...

Students recognize that density determines whether objects sink or float.  For this sink or float lesson, students experiment with plastic in three liquids. students drop their objects into the liquids and observe and record their...

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

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.

In this float or sink worksheet, 8th graders solve 1 science/math puzzle about displacement of water; the answer is available online.

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Integrate science and literature by using the scientific method to test the veracity of the floating peach described in Roald Dahl's James and the Giant Peach. Clips from a Bill Nye: The Science Guy episode about buoyancy frontload...

Students examine why some objects float or sink. In this physics lesson, students engage in several mini-experiments which challenge them to draw their own conclusions regarding why certain objects sink or float. An example of one...

Middle schoolers are introduced to the concept of buoyancy. The Video used in this instructional activity demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and...

Learners define the terms "mass," "volume," and "density." The relationship between these three terms is established. They observe the differences between Regular and Diet Coke. They develop an hypotheses about why a can of Regular Coke...
