Discover and apply concepts of density and buoyancy.

Description

In this kit, students discover and apply the concepts of density and buoyancy by creating a sugar or salt gradient in a plastic column and floating five small spheres in the solution. Each sphere floats at a different level! Includes full instructions and write-ups as well as spheres made of polyethylene, polystyrene, nylon, acrylic, and cellulose acetate. Unknown plastics are also included for student density determination. Great for an elementary science table or as a terrific lab for middle school, high school or college. Container not included.

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 Density Spheres 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 Density Spheres to determine which materials have the properties that are best suited for an intended purpose.

5-PS1-1

Students can use the Density Spheres 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 different materials in the Density Spheres to identify materials based on their properties.

MS-PS1-1

Students can use the Density Spheres in an investigation to develop models to describe the atomic composition of simple molecules and extended structures.

HS-PS1-1

Students can use the Density Spheres 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 Density Spheres in an investigation to communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.

Suggested Science Idea(s)

This Density Spheres is an awesome demonstration for density, solubility, miscibility and the salting effect. All students will be amazed by the actions the beads take. Due to the unexpected results in the bottle, secondary students have to use science to dissect an explanation for the layering. Great inquiry opportunities for all students. Some teachers never give away the secret.

Students can use the Density Spheres in an investigation of density. Shake up the bottle and let them sketch the various motions of the beads. For primary grades, a second bottle can be prepared with some food coloring added to the water solution, to bring a more concrete explanation. Secondary students may be able to use chemistry to decipher the paradox.
