Product Details

This microscale version of the iodine clock challenge will surely spark inquiry-based questions in your lab! Students run and time eight trials simultaneously! The effects of concentration, temperature and a catalyst on the rate of an iodine clock reaction are tested. A starch solution acts as an indicator and produces a dark blue reaction endpoint. All chemicals and specialized equipment are provided.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. One classroom timer is required and available separately.

Performance Expectations

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
