Product Details

The best way to teach the scientific method is to actually use the scientific method! In this guided-inquiry lab, students determine how different factors will affect the rate at which a solid dissolves in a liquid by following the steps of the scientific method. Students devise experiments to measure the effects of each variable, conduct the necessary tests and analyze and graph the results. Supplementary information is provided in the teacher notes so that the lab may be performed as either a student-designed experiment or as a more conventional experiment with step-by-step instructions. Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions and all necessary chemicals and consumable supplies.

Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Performance Expectations

MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS1-6: Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes.
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.
