Product Details

Mass, volume, and density are concepts you teach over and over again during the school year in many different ways. Help students understand the relationships between mass, volume and density with our Equal Mass Kit. Five cylindrical objects, made of different materials with differing lengths, all have exactly the same mass and radius. Thus, density is inversely proportional to length. Contains five cylinders: brass, aluminum, nylon, PVC, and polyethylene-all 1/2" in diameter and 15 g in mass. Classroom set includes 15 sets of materials, enough for 30 students working in pairs.

Performance Expectations

MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
