Ms. Jordan and Mr. Tygesson co-taught a density lab to Ms. Jordan’s 8th-grade science class.
Students learned that density is the relationship between mass, volume, density, and flotation. It explains why some objects float while other objects sink. The density of any material can be determined by dividing the material’s mass by its volume.
Standard: SC.8.P.8.3 Explore and describe the densities of various materials through measurement of their masses and volumes.
Big Idea: Properties of Matter –
A. All objects and substances in the world are made of matter. Matter has two fundamental properties: matter takes up space and matter has mass which gives it inertia.
B. Objects and substances can be classified by their physical and chemical properties. Mass is the amount of matter (or “stuff”) in an object. Weight, on the other hand, is the measure of the force of attraction (gravitational force) between an object and Earth.
