Acid/Base reaction lesson in full color

Science comes to life at TEC

Teacher Cassandra Weason took advantage of the beautiful day Wednesday to make a mess. The lesson on acid and base reactions is a favorite for students who bring a white t-shirt from home and use colors in buckets to create art.

Students wait to see their results

The chemical process of tie-dying relies on dyes that are called fiber-reactive. A chemical reaction takes place between the dye molecules and the fabric molecules. The dye bonds to the cotton and actually becomes a part of the fabric. In this manner, the dyes are permanent and vibrant even after several washings.

Students took part in the project Wednesday and will see the results Thursday.
