pH, Indicators and Dyes STEM Kit

This kit is a unique teaching tool for introducing your students to the chemistry behind plant pigments (the blueberry biopigment cyanidin) and how they can be used as pH indicators and fabric dyes. Students use their knowledge to create their own pH test strips and evaluate them against a commercial type.
Includes materials for four detailed activities featuring ‘model’ and ‘inquiry’ investigation paths - a total of 11 investigational activities, which can accommodate up to 40 students! Also contains a DVD with PDF Teacher and Student Guides and other digital content.
Covered concepts include: data analysis, accuracy vs. precision, biopigment structure, pH, pH scale, pH indicators, stains and dyes, acids, bases, acid- base interactions, solutions, and self-ionization of water.
