Chemistry students get groovy with tie dye

Tie Dying is a practice that has been embraced ever since the hippy era in the 1960’s, but for Heritage High school chemists it is also a very hands-on way to learn a few concepts.

“We’ve been doing the tie dye lab in the Science department for several years. It is the most expensive lab the department conducts but it’s a great way to end the year with a little creativity, and it also reminds students that chemistry is at work all the time,” says chemistry teacher Corey Brueckner.

Students pre-soak clothing in Soda Ash fixer solution which allows the fiber reactive dyes to work at room temperature. These fiber reactive dyes attach to the cellulose fibers in white cotton using a covalent (electron sharing) bond. The molecules in the die carry “chromophore” which allows for the fabric to absorb and reflect varying spectra of light.

“I thought tie dying was the best practical lab we’ve done all year because it reminded me that even simple activities like dying clothes take complex chemical reactions,” says Lexi Fischel ’17.

Students are allowed a lot of creative freedom, as they can dye any fabric that will take the colors and can choose from any color combination

“I’ve seen people die all sorts of things, from socks to white comforters. It’s always fun to see how creative people can get with it,” says Brueckner.

College Admission Fees Deter Students

    At this point in the year, most schools have sent out their acceptance and rejection letters, and seniors have solidified their plans. Many selective colleges report another record year for applications according to markerplace.org. This can only mean that they rejected more students. But not before collecting their application fees.

Many students feel as if they should apply to multiple schools. They are told to apply to their “safety schools” to their “match school” and to their “dream school,” however this can be an expensive proposition as each application can cost up to $70.

“I have seen students get into their dream schools but are put on the waiting lists to get into their safety school so I think it is important to at least apply to your top schools because you never know,” says Mrs. Lisa Zolle, Science teacher.

In some cases application costs can close some doors that would otherwise be open, however they do serve an important purpose.

“When I see that a school has lower acceptance rate, I automatically want to try to get into that school because it seems more selective,” says Lindsay Resizer ’17.

With this mentality, higher application rates means more selectivity, ultimately heightening the university’s image while funding the application process.

   Ultimately completing an application is daunting as more and more students are competing for a spot at their dream school.
