Product Details

Glowing gummy worms! In this colorful demonstration “gummy worm” polymers containing three different types of dyes fluoresce when exposed to an ultraviolet (black) light. As the glowing worms emerge from the solutions, students see what happens when long polymer chains are “tied together” by cross-linking. Your students will be captivated while learning more about polymers and fluorescence with this unforgettable demonstration. Includes detailed instructions and enough material to perform the activity as written at least 25 times. Requires a ultraviolet lamp (sold separately). Concepts: Polymers, cross-linking, fluorescence. Time Required: 15 minutes Materials Provided: Calcium chloride, fluorescein, rhodamine B, sodium alginate, tonic water, forceps, jumbo pipets. Note: An ultraviolet lamp is required and available separately.


Materials Included in Kit: 
Calcium chloride solution, 0.1 M, 500 mL
Fluorescein solution, 1%, 30 mL
Rhodamine B solution, 1%, 30 mL
Sodium alginate, 10 g
Tonic water, 10 oz bottle

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.
MS-PS1-3. Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
MS-PS4-2. Develop and use a model to describe that waves are reflected, absorbed, or transmitted through various materials.
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.
