Acid (and Base) Rainbows

Get kids excited about science and experimentation through watching for color changes in several different test materials. For this lesson you’ll find objectives, a materials list, reasons for students to understand acid and base, the procedure, as well as worksheets to print off for the many measurements. The extension activities encourage even more critical thinking, and the lesson plan gives ways of scaling down the lesson for younger students.
