The document discusses the Chemical Education Material Study (CHEM Study), an innovative science education program developed in the United States and United Kingdom in the 1950s-60s. CHEM Study aimed to develop new high school chemistry curricula and teaching materials through experimentation. It emphasized hands-on learning through experiments where students could discover principles themselves. The program involved developing and testing textbooks, labs, films and other materials to improve chemistry instruction and engage students in problem-solving.
