Product Information

Thousands of years ago, before people knew about advanced concepts in chemistry, dyes and pigments were extracted from natural materials.

Science teacher David Budnik developed this hands-on kit that lets students extract their own dyes from plants. Students can make red, yellow and brown dyes; use these dyes on fabric samples; then study the results of the dyes both with and without mordants (metal salt solutions used to ensure colorfastness).

Includes materials for nine student groups and instructions.

Great for Explaining Gram Staining
Reviewed By:  Shelley
I used this lab with my microbiology students when we learned about the Gram staining process and microscopy in general. It is a great illustration of what a 'mordant' is and one of the ways it works. It is also a fun activity for biology students when they are studying plants. It ties in a little history and lets the kids do a 'craft', which they love. The consumables are easily replaced, and makes this activity worth the initial purchase price.
