Students eagerly investigate the properties of substances as they make their own personal brands of paste, toothpaste, cola, and ice cream. The activities have been designed to convey key science/mathematics skills and concepts, provide motivating real-life experiences with chemistry, and build comprehension of cause and effect, central to later understanding of controlled experimentation. Secret Formulas speaks to the need expressed by many primary school teachers for more high-quality physical science activities.
