In Floating and Sinking Lesson 6, students explore how to make something that sinks float.

Floating and Sinking

Learn how shape, volume, and density cause an object to sink or float in water in this physical science unit for grades 4-6. Early investigations familiarize students with objects that will sink or float in water and will help them separate weight from density. Future investigations will challenge students to make objects that sink float and keep those objects afloat when weight is added. This unit teaches valuable problem-solving skills when students build clay or foil boats, encourages students to work through problems and improve their creations once they have found a sufficient solution.

The STC Program™ is a basal, inquiry-based science curriculum for grades K–10 that covers life, earth, and physical sciences with technology. STC™ was developed by the National Science Resources Center based on research into how students learn best. The NSRC was established by the National Academies and the Smithsonian Institution.

Benefits of using this kit:
	STC kits contain all of the materials you’ll need to teach the unit
	Inquiry science is a proven alternative to textbook programs
	Supplemental literacy pieces in the Teacher’s Guide, STC BOOKS™, and KIDS DISCOVER connect classroom content to the real world
	2-use kits and refurbishment sets provide enough materials for a second non-concurrent use

By the end of the unit your students will understand that:

	Several factors affect the buoyancy of an object.
	Water pushes up on floating and sinking objects with a buoyant force. Because of this, objects appear to weigh less when submerged.
	The amount of liquid an object displaces is directly related to its volume.
	The buoyant force on an object varies with the density of the liquid in which it is submerged.
	Objects that weigh more than an equal volume of water sink; those that weigh less float.

In the Kit:

	Teacher’s Guide with lesson instructions, unit overview with background information, and sections on assessment, notebooking, literacy, and more
	Enough materials to lead a class of 30 students through all lessons in the unit
