Bond: a feeling or an agreement that unites two or more individuals.
pH: a number that describes how acidic or basic a substance is. The pH scale goes is from 1-14, with lower numbers being more acidic and higher numbers being more basic.
Protein: a type of molecule found in the cells of living things, made up of special building blocks called amino acids.
The short activity Breaking Proteins helps students visualize how conditions can affect protein structure, and the ability of proteins to function. The activity can be done with simple materials found in most homes. The activity is written for students at a middle school or higher level, but with more intense guidance, this activity is useful for students of any age. Download the classroom packet (PDF).
