Green Hands-On Experiments for Teachers

Motivation
Sustainably designed chemical experiments are highly attractive for middle and high schools because they provide a hands-on experience addressing science standards without the need for specialized equipment, laboratory facilities, or waste disposal. Therefore, this type of activities is uniquely suited for STEM education and professional development for teachers. The National Research Council report "A Framework of K-12 Science Education"and the April 2013 Draft of the Next Generation Science Standards both strongly emphasize hands-on learning in science education. Therefore, the objective of the experiments provided on this website is to provide teachers with green hands-on experiments that can be implemented in the classroom.



Experiments, Links to Materials, Scientific Principles, and Sustainability


For all experiments that are performed indoors, it is recommended to provide an aluminum pan per student or per experiment to simplify cleanup. All materials used are non-hazardous; thus, waste liquids can be deposited down the drain and solids into regular solid waste. CAREFUL for experiment 11 "hard liquids": all “slime” made from corn starch has to be deposited as SOLID WASTE, as it can clog the drain!!!!!

Design of Experiments
Every experiment in our collection provides background information about the scientific principles that can be illustrated through its use and links to information about material requirements. Furthermore, all experiments are cross-referenced with the relevant Next Generation Science Standards and current High School Standards for Massachusetts. We also provide explanations of how the experiments can be used to illustrate current issues in sustainability and what the scientific contributions to address these challenges are.
