Chromaflies - Chromatography Butterflies Bulletin Board

I'm pedagogy chemical scientific discipline this twelvemonth nether some not-so-normal circumstances.

1. I'm non a trained chemical scientific discipline teacher. I'm non fifty-fifty a trained scientific discipline teacher. I'm a math instructor who enjoyed chemical scientific discipline inward high schoolhouse together with was able to scream back plenty from AP Chemistry to go yesteryear the chemical scientific discipline certification test.
2. I never prepare out to learn science. Budget cuts possess got resulted inward my schoolhouse losing a scientific discipline teacher. It turns out that a schoolhouse our size (180 students 9th-12th grade) cannot role amongst solely i scientific discipline teacher. Math is closed plenty to science, then I got the job.
3. I'm pedagogy chemical scientific discipline to students who don't possess got a potent background inward lab sciences. Most of my students possess got never been required to write a lab study before.
4. I'm pedagogy chemical scientific discipline inward a non-lab classroom amongst carpet. We can't actually create labs requiring flames, unsafe chemicals, drinking glass lab ware, fume hoods, or a i K 1000 other things. This actually limits the labs that nosotros tin sack do.
5. It's been several years since my schoolhouse has offered chemistry.
6. We possess got null budget for scientific discipline lab supplies. So, the solely supplies I possess got are ones I've establish lying around the schoolhouse from years yesteryear or ones I've purchased from my ain pocket. 

I even then desire to proceed my chemical scientific discipline cast equally hands-on equally possible. This has meant that I possess got to learn creative to notice lab activities that my students tin sack even then create nether these circumstances.

At the terminate of our start unit, nosotros did a mixture separation lab which I possess got yet to spider web log about. I saw scream of a chromatography lab inward some other textbook, together with I instantly prepare nearly to figure out how I could comprise this inward my classroom. I don't possess got access to chromatography paper, but I create possess got a giant packet of java filters I establish inward the scientific discipline lab of our old, abandoned high school.

So, I decided that nosotros would possess got the road of java filter chromatography instead of the to a greater extent than formal chromatography experiments I could notice written upward inward books together with online.

Before I learn whatsoever further, I possess got to portion our concluding product.

Want to brand all of your algebra students loathe you? Tell them that they aren't allowed to brand their ain chromatography butterfly because they are inward algebra, non chemistry.

For supplies, you'll demand java filters, markers, water, together with a container to concur your experiment. We used both plastic beakers together with plastic cups.

My students establish that the experiment worked faster inward a loving cup than a beaker. One grouping of students did their start java filter inward a beaker together with their 2d inward a cup. The i inward the loving cup finished start despite existence started last! 

For the markers, I possess got establish that Expo Vis a Vis markers (affiliate link) together with Mr. Sketch markers (affiliate link) operate the best. Highlighters, Sharpies, together with Dry Erase Markers create non work.

To begin, flatten your java filter. Make a blueprint around where the circle is at the bottom of the java filter. You don't desire your blueprint to extend whatsoever closer to the middle of the circular java filter than this circle.

Here are some of our designs:

Here's my example. I used bluish together with dark vis a vis markers.

Once your blueprint is finished, crimp your java filter inward one-half together with one-half in i lawsuit to a greater extent than similar y'all are preparing to brand a snowflake.

Unfold it a bit, but brand certain y'all proceed the indicate at the bottom of the java filter.

Place simply a pocket-size combat of H2O (solvent) inward the bottom of your loving cup or beaker. Place your java filter inward then that ONLY the tip is touching the water. It is of import that none of the ink touches the water.

If the ink does impact the water, the ink volition spread to the H2O instead of the java filter.

Here are a few that were messed upward due to the ink touching the water.

Once the java filter is inward the water, the waiting game begins. At this point, I possess got my students read an article together with respond some questions nearly chromatography. Even though we're non doing a technical chromatography lab, I even then desire my students to empathize what chromatography is together with how it is used inward laboratories.

As students read nearly chromatography inward the article, they learn to come across it inward action.

Here's mine (the i amongst the dots together with stars) after a few minutes: 

Many inks are non made upward of simply a unmarried color of ink. Some of the ink colors are to a greater extent than attracted to the H2O traveling through the java filter. These ink colors volition motion up. Other ink colors are to a greater extent than attracted to the java filter than the water. These volition exhibit upward lower on the java filter.

Enjoy these pictures of our chromatography experiments inward progress.

Watch closely until the H2O reaches the edges of the java filter. Now, it's fourth dimension to trace out the designs together with house them on newspaper to dry.

Remember my blueprint amongst the circles together with stars? It's the bottom blueprint inward the painting exhibit below.

Here's some pictures of my chemical scientific discipline students' finished designs. It was awesome to listen them notice how the colors of their concluding blueprint differed from the master copy colors of markers they had used. One daughter exclaimed, "Where did the pinkish come upward from? I used orange!" 

There were moisture java filters on almost every apartment surface of my classroom!

After drying overnight, nosotros turned them into java filter butterflies the side yesteryear side day.

To create this, crimp the middle of your java filter spell fluffing the exterior to brand wings. You solely demand one-half a pipage cleaner to brand antenna, then cutting i inward one-half for this purpose.

Wrap the pipage cleaner around the butterfly's middle together with twist.

My students actually enjoyed this activity! Several mentioned that they were going to create it in i lawsuit to a greater extent than at dwelling amongst younger siblings/cousins. How cute is that?!? 

And, weeks later, my algebra students are even then scream for if they are always going to learn to create the java filter activity!
