Megan was watching a show about Nicola Tesla. She was so impressed that afterwards she decided Nicola needed an "emblem". She made one, put it on her Etsy site and the rest is history. The response was great and an idea was born. Nicola was the first of many emblems. Megan said she is not sure if she is a nerd who loves art or an artist who embraced her inner geek. Either way, her stickers, posters, t-shirts, flashcards and designs are super cool.
ChemEd X is preparing for CHEMED 2017! If you are attending the conference, we hope you will stop by our booth in the exhibit hall and introduce yourself.
I recently watched a video in which a chemist (who goes by the nickname “NurdRage”) activated a chemiluminescent reaction by vapor deposition. I wanted to try it out for myself! Unfortunately, oxalyl chloride is toxic, corrosive, and a lachrymator. Thus, the experiment conducted by NurdRage needs to be conducted in a hood, and it is not particularly amenable to simple presentations. I began to wonder how I could create this vapor activated chemiluminescence using simple materials.
Over the past 30 years, numerous articles have been written about the importance of student teacher relationships. The National Education Association, NEA, offers advice for beginning teachers that includes establishing the classroom climate, conducting class efficiently, and reaching all students. When teachers effectively connect to their students, discipline problems decrease and student engagement increases.
This post was submitted for the 2017 ChemEd X Call for Contributions: Creating a Classroom Culture.
In Chemical Mystery #10, plastic straws are observed to “magically” change color when waved in the air. Check out the explanation and the video.
In this simple trick, colors are made to "magically" appear and disappear on a straw. This science experiment is very easy to do...if you know your chemistry!
I saw the process of students thinking like scientists but what I struggled with, and I imagine many others do as well, is how students work together in groups. Yes...I know it is important but is this a big battle that I want to fight? I was fortunate to meet several people who have developed some wonderful “tricks of the trade” to help students work as “teams”.
This Call for Contributions has closed. As many school districts are moving toward incorporating student-centered curriculum and pedagogy, many teachers have found that it can be difficult to initiate a classroom culture that encourages students to embrace the change which calls for them to engage in discussions and take more responsibility for their own learning. Chemical Education Xchange (ChemEd X) is interested in learning about how teachers are creating a culture of student-centered learning in their classrooms. For this reason, we are initiating our content specific CALL FOR CONTRIBUTIONS centered on the concept of “Creating a Classroom Culture”.

If rhubarb stem is placed in a solution of permanganate, the purple permanganate ion is reduced to the colorless Mn2+ ion. It is thought that the oxalic acid present in rhubarb causes this reduction. The investigations presented in this post provide evidence that this may not be the whole story...
