Ah, the trials and tribulations of teaching science to young teen girls and boys...
I posted before about the number of occasions where my whiteboard sketches always ended up looking like oversize penises, with much mirth from my young students.
Well my last lesson was the ultimate in side-splitting, teenage mirth.
We were learning about photosynthesis in plants, and I like to show short videos from YouTube to illustrate the processes.
So I find a 3 minute video on gas exchange in plants, download it and check that it's suitable for the class.. Crucially, I only checked the first 2 minutes of the video....
So in the class I start to play the video. All goes well and the students are watching closely when this happens... (see the video clip with this post). I took a screen grab if you don't want to download the video.
Sure, it's a good illustration of the scientific process that's involved. But you can understand that my whole class collapsed in fits of laughter, (and there was no way that I could keep a serious face).
I recovered the situation by saying that after this memorable video, I was sure that all of my students would be able to recollect and draw these diagrams when asked in the end-of-semester exam.
Phew! Needed a drink after that hilarious lesson.
