Product Details

Are all toothpastes the same? Students will learn about tooth decay and the function of toothpaste. Students will perform experiments to determine the abrasiveness, pH, fluoride content and foaming ability of five different toothpaste brands. Students will use background and cost/oz information to evaluate the results and to form judgments and conclusions about the effectiveness of each toothpaste. includes detailed Teacher Notes, background information, sample data, helpful tips and reproducible student handouts.

Complete for 24 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. Toothpaste samples are not provided.

Performance Expectations

MS-ETS1-2: Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.
MS-ETS1-3: Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.
HS-PS2-6: Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials.
