As a teacher, it is important to capitalize on teachable moments. A small discussion, comment, or even an action from a student can lead to a brilliant impromptu lesson.
Case in point, last week I noticed that a student in my class was applying chapstick to her lips every few minutes. Her chapstick was becoming a distraction to her work. Not only that, but she was wasting a resource that should have lasted her a few weeks.
I immediately saw a connection to the glue sticks we have in the classroom. Quite often the students don’t roll down the glue and affix the cap properly when they have finished using it. Other students roll the glue all the way up to the top, or apply too much (like my student was doing with her chapstick)
I found a glue stick that was just about empty and held it up for the class.
“How does this work?” I asked.
One student replied, “You take off the cap and then put it on the paper.”
I did what she said and placed the glue stick cap on a piece of paper.
I said, “Come on, you should be able to explain how something as easy as a glue stick works?”
This is actually a good exercise in using precise language. And it is not as easy as it sounds. I was trying to challenge my students.
It took a while but they were finally able to direct me to use a glue stick correctly to glue two pieces of paper together.
After that, I held up the glue stick and asked the students, “How many parts do you think a gluestick has?”
Most of the students yelled out “4” but one said “5”
I took apart the gluestick and we examined each piece. I drew each piece on the Smartboard as well.
We could now see that a gluestick is a simple machine consisting of 5 parts. “Great answer!”
Glue sticks and Chapstick are built the same way.
Here are the component parts;
1) The handle that you turn is actually a screw. You can see it once you take off the top part that holds the glue.
2) The piece that screws on to this is a platform but we used the term “nut” for this exercise. The screw mechanism is like a bolt and the nut attaches to it.
3) Next we have the glue itself. This is the part of the glue stick that gets used up.
4) The casing or plastic shell is the next piece.
5) And finally, we have the cap or lid.
I was then able to talk about why we should be “Wise in the use of our resources” – an old Scouts Canada motto that has really stuck with me.
We only have so much resources in the world and in the classroom. We need to use the things we do have in a responsible manner.
Sure, this impromptu lesson took 20 minutes of my day that I had planned to teach something else, but this lesson was
We compared our lip balm and looked at the volume of ointment in each container.
This was one of the best lessons I delivered all year long and it was sparked by what was happening in my classroom at the time. I didn’t plan this lesson. In fact, it was actually a disruption to my day but good teachers can recognize these teachable moments and cash in on them.
