Chemicals for Science Education
Chemicals for science education are available in easy-to-use formats with instructions for students to be introduced to a variety of subjects. These chemicals can be purchased in individual amounts or bulk kits for compatibility with classroom-sized demonstrations or independent studies. Products are designed for educational and teaching laboratories, and may or may not come with a certificate of analysis when ordered.
Innovating Science® NYS Investigations for Life Science: Lactose Intolerance - Inheritance and Variation of Traits
Lactose intolerance is common, but is actually a recessive genetic trait! Humans and other mammals are only meant to drink milk as infants and as they grow, they lose the ability to digest lactose. As populations began to develop, the domestication of cows and drinking milk into adulthood became more common, leading to a tolerance for lactose. Learn about variation, inheritance, and the role of DNA and proteins in expression of traits in this three-part laboratory activity.
