Lowell - International School teacher
by Lowell Thomson
Sun, 08/20/2017 - 09:09

The advantages of international schools vary by individual, but certainly the opportunity to travel and see the world is by far the most common reason teachers move overseas. Smaller class sizes are typical, along with fewer teaching periods in your schedule. As an example, I average about 20 students per class right now, teaching 5 of 8 class periods. This is certainly less than my average of 30-35, teaching six of eight class periods at my last public school in the U.S.

Fortune Teller Fish

What is the very first impression that I want to make on students? Do I want to pass out a bunch of papers about the syllabus, rules and policies? Do I want kids to be thinking and acting like scientists? Deep down inside, my hope is always for the second idea. I decided to steal an idea I got from master chemistry teacher Linda Ford at an local ACS meeting. Linda introduced a group of teachers to the "Miracle Fortune Teller Fish".

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.

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”.
