This series of interactive simulations provide students with the ability to experiment with reaction concentration and temperature to observe the effects on a chemical reaction. This simulation is coupled with questions that lead students to develop a conceptual understanding about how these factors affect reaction rates. This review focuses only on the Day 1 activities within the site, accessed on pages 1-5. In this portion of the lesson,students are directed to explore investigations by accompanying text, questions, goals and specific challenges. The variables of temperature and concentration are addressed separately, and then the student is asked to manipulate both variables together with the size of the container in the end challenge. Simulations can be paused for closer investigation, reset, and replayed numerous times. Multiple choice and short response questions can be saved and sent in a report to the teacher. The simulations do not reference specific temperatures, but ranges qualitatively from low to high.
