Product Details

Captivate student interest by growing GIANT crystals! In this hands-on activity, students will cultivate and grow giant alum crystals in a supersaturated solution from a single seed crystal. They will be amazed at how quickly their alum crystal begins growing into its natural, cubic structure and how it continues to grow larger and larger over a period of weeks or months. This is an excellent activity to use when discussing saturation, supersaturation and solid state chemistry. Alum crystals are easy to grow—an excellent choice for an introductory crystal-growing activity. Includes thread, enough aluminum potassium sulfate to grow 15 giant alum crystals and detailed instructions.

Complete for 30 students working in pairs.

Performance Expectations

MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-3: Gather and make sense of information to describe that synthetic materials come from natural resources and impact society.
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-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
