Product Details

Wow! A gravity-defying demonstration that will stop students in their tracks! A beaker is filled with a 50-foot-long string of beads. With just a slight pull on one end of the chain, the beads will suddenly lift themselves out of and come tumbling over the side of the upright beaker. This amazing feat mirrors the behavior of “self-siphoning” polymer gels, such as polyethylene oxide. Use this highly visual demonstration to illustrate the structure of polymers. This low-cost demonstration may be used over and over again. It’s sure to be a hit in your classroom! Teacher Demonstration Notes included.

Concepts: Polymers, monomers.
Time Required: 15 minutes

Performance Expectations

MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
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.
HS-ESS2-5: Plan and conduct an investigation of the properties of water and its effects on Earth materials and surface processes.
