## Product Details

A gallon of milk seems to weigh more than the fluffy pillow you sleep on. You probably wouldn't confuse these two materials nor have trouble thinking about their density. But how about steel versus iron? Aluminum versus tin? Density is a very measurable property even for solids that have a similar appearance. In this unique kit, students determine the density of an unknown metal slab and compare it to previously measured metal cubes. Very clever and very involving for students. 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.
