Grades 9-12. This kit addresses a timely topic - biodiesel - while practicing timeless laboratory techniques, such as titration. Students determine the quantity of reagents needed to produce a batch of biodiesel, run the reaction, and purify the finished product.
The 3-step experiment fills three 50-minute classes with basic chemistry techniques and introduces students to a fascinating new fuel technology. They can even collect and use their own feedstock samples as starting material.
Materials are sufficient for 30 students working in groups of 3.
