This kit helps students understand density as an intrinsic quality of matter that remains the same regardless of sample attributes such as size, shape, and color. Equally important, students also practice the fundamentals of inquiry and experimental design. 

These experiences help prepare students for common topics found in classroom and statewide assessments. Students first reveal their preconceptions about several aspects of density that are often misunderstood. Each of these aspects is then examined through student-designed experiments which provide evidence for students to use when they revisit and revise their initial preconceptions. 

Unique equipment designed by LAB-AIDS‚® provides students the ability to easily and accurately collect, compare, and analyze data from various materials. A comprehensive teacher„¢s guide includes performance criteria and both multiple choice and constructed response assessment items.
