Engineering Design Challenge

In this lab experience, students are challenged to devise a method to increase the amount of carbon dioxide in seltzer water. Students will discover that increasing pressure and cooling the solution causes a shift where more carbon dioxide can dissolve in the solution. For best results, pressure and cooling, together, gives the most color change. In the higher levels, students will also relate this phenomena to real-world problems and manufacturing.
