Did you know Chem-E-Car was initially inspired by a plastics recycling competition in the early 1990s? Learn more about its origins and history in this two-part series.
Students will make a CSTR out of recycled materials to neutralize low concentrations of vinegar and baking soda. They will then test different flow rates to achieve steady state and find actual conversion using pH to compare to the theoretical conversion obtained with CSTR equations. ...

In this module, students act as textile engineers to decide which of three methods of dyeing they would choose for their manufacturing facility by investigating scientific and practical engineering considerations such as cost, amount of waste and color quantity and quality. While conducting samples of dyes that use food dye, hibiscus tea, and beets, students dive deeper into solid-liquid extraction by exploring the role of higher temperatures and table salt on the dyeing process.

In this module, we walk students through the basics of reaction chemistry. Briefly, we will talk about elements, the periodic table, and how every reaction requires a driving force and the proper orientation to form a new product. We will then show kids some different examples of chemical reactions which utilize a common reactant but yield different products. This will lead to our overarching message that everything in this universe is made primarily of oxygen, nitrogen, carbon, and hydrogen (even us!) which we think will get students to start to think about how much chemistry informs us...
