This scavenger hunt activity turns a safety lesson (with vocabulary, reading/interpreting an SDS, and finding chemicals in our everyday life) into a FUN MYSTERY! The activity consists of two parts, A & B.
Part A requires students to look up definitions of common vocabulary found on Chemical SDS (safety data sheets). Then, students look through common household items to find products that contain a particular chemical - isopropyl alcohol. I have my students complete this part at home. However, it would be an EXCELLENT modification to have empty bottles of household chemicals available in the classroom! Once students have located ONE product that contains this chemical, they discuss their findings with other students. This provides insight into personal, everyday exposure to chemicals and the relevance of an SDS.
For Part B, the teacher fools students into believing the school drinking water is dangerous. Using vocabulary knowledge from Part A, students read through several SDS and identify the chemical that the teacher used in their trick. This requires cooperative learning, reading comprehension, prior knowledge of the density of water, and critical thinking skills to solve the mystery!
This product includes teacher instructions, a student activity sheet, and an answer key in WORD format, so they're completely editable.
