The author shares a series of resources she has created that are built around a post here on ChemEd X about popping a balloon with an orange peel and the concept of polarity.

A couple of years ago I was asked to be a mentor teacher to a new teacher. We sat in on what seemed endless meetings for first year teachers. Frank Forsthoefel told a story about his young daughter. His daughter's teacher called home to talk to her...before the first day of school. He mentioned the positive impact it had on both him and his daughter. A light turned on. What would happen if I called home to everyone of my students BEFORE the first day of school?

glow sticks and filter paper

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.

Color-changing straw

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!

roles and teamwork
by Chad Husting
Fri, 06/30/2017 - 13:23

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”.

I love Chemistry bumper sticker

POGIL stands for "Process Oriented Guided Inquiry Learning". Over the years I have accidentally and somewhat intentionally been using POGIL activities. Students must work in teams, examine models and answer questions that become more complex based on the models and students hopefully build knowledge. I have had my ups and downs. It has been messy. Bottom is what almost always happens...I eavesdrop on students talking like scientists. It is student centered and the comments would never come from students if I sat back and lectured. Somehow, I wound up at this conference for "advanced" POGIL practitioners. I am trying to keep it a secret that I have never really been advanced at anything and am hoping that by the time anyone figures this out the conference will be over.

organizing laboratory equipment
by Doug Ragan

I decided to take the time and to do some needed inventory.  I wanted to match equipment to its designated table.  Next, I wanted to make sure that each of my eight lab tables had the proper equipment needed to eliminate no more missing equipment.  Sure enough, as I began the inventory project, I had several tables missing equipment, so once everything was laid out and counted and organized then I had to make sure it was going to stay that way.  I had several rolls of colored tape and it was easy to then begin marking each of the pieces of equipment and glassware with tape.
