A 48-piece density set of twelve different materials.

Description

Our 48-piece density set provides four different sized specimens for each of twelve different materials. Each set of four density samples comes in its own tube for easy classroom management. Measuring the mass and volume of each sample specimen allows students to plot Mass vs. Volume, and thus, determine the density of their individual material by calculating the slope of the resulting line. Materials include: aluminum, PVC, acrylic, wood, polypropylene, phenolic, polyurethane and PTFE.

Classroom density assortment
May 29, 2012
I like using the density assortment cylinders with my honors chemistry-I kids. It gives them a great visual as to how the same substance can be different sizes but yet have the same density. They make terrific graphs using these cylinders and calculate slope to find density. This is probably the best set I have come across to use in my class.

### NGSS

This product will support your students' understanding of the Next Generation Science Standards (NGSS)*, as shown in the table below.

 Elementary Middle School High School 2-PS1-1 Students can use the Classroom Density Assortment in an investigation to describe and classify different kinds of materials by their observable properties. 2-PS1-2 Students can analyze data obtained from testing the Classroom Density Assortment to determine which materials have the properties that are best suited for an intended purpose. 5-PS1-1 Students can use the Classroom Density Assortment in an investigation to develop a model to describe that matter is made of particles too small to be seen. 5-PS1-3 Students can make observations and measurements of the two different materials in the Classroom Density Assortment to identify materials based on their properties. MS-PS1-1 Students can use the Classroom Density Assortment in an investigation to develop models to describe the atomic composition of simple molecules and extended structures. HS-PS1-1 Students can use the Classroom Density Assortment in an investigation to predict properties of elements. Students can 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-PS2-6 Students can use the Classroom Density Assortment in an investigation to communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.

Students can use the Classroom Density Assortment in a variety of investigations to make sense of the subatomic structure of matter (metals) and how that relates to its properties. Secondary students can do the math to determine the density of each of the samples and establish an understanding of the mathematical slope developed from the data.
