Not being keen on the stench of cigarettes filling the Science block despite the use of a fume cupboard, I put this video demo together which shows the difference between lab air, filter tip cigarette & unfiltered cigarette
Something went wrong, please try again later.
Saves me having to move labs and disrupt the classes, thanks.
Thanks for this, a very useful resource which saves filling my lab with smoke.<br />
Very helpful video and worksheet. It's a shame that the worksheet doesn't quite match the video. The limewater and U.I. tubes are the other way around, which will be confusing for the students. Also, there is no thermometer used in the demonstration. Also 3 experiments were demonstrated (fresh air, unfiltered and filtered cigarettes) but only two are on the worksheet, so I'll need to modify that. Nevertheless, a very useful resource. Thankyou :-)
Not very engaging.
Thanks for sharing that, I hate doing the smoking demonstration too! Your video has a really good commentary too.
