Gumdrop Crystal Models
A great way to learn about molecular structures is to make a model. Gumdrops and toothpicks are used to construct crystal models. The models are based on theories of crystal shapes that occur because of positive and or negatively charged...

Polymers and Crystals: Their Role in Food Science
Blend chemistry with cooking in this exploration of polymers, carbohydrates, and food science. Experimenting with gelatin produces concrete examples of the bonding and ploymerization discussed in the lesson. Copious, comprehensive...

Diaper Inquiry
Fifth graders carefully examine and investigate the products contained in a diaper. They particularly analyze the crystal sodium polyacrylate, a product developed for use in astronaut diapers. They follow the scientific method, forming...

Watching Crystals Grow
Learners observe crystal growth of Epsom salts and the variables that hinder or help their nucleation and growth. They illustrate a series of drawings/pictures as the crystals grow. They look for the different shapes they form as well...
Curated OER
Crystal Structure Lab
Students study and examine crystal shape. They create the two basic unit cells (one a tetrahedron) out of pipe cleaners and dip them into soapy water to see if they can form bubbles to represent a silicon atom in the center of a...

Integrating Physical Science and the Geological Environment
Students undertake a series of experiments and activities related to geology, especially in Connecticut. They evaluate types of rocks, minerals, and crystals, exploring the main concepts of geology.
