Teaching Tips

Stopping to question and observe after each condition would assure the teacher that the students have a clear understanding of what is taking place.

Instructor may want to provide student guidance on how to record their data.

Caution should be taken if instructor chooses to have students light the matches.

It may be helpful for an instructor to perform the experiment for themselves first before using it with students so they understand what the bottles will look like under each experimental condition.
