I haven't been on YouTube in quite a long time to look for bryophyte videos. My
labmate Juan Carlos recommended this video. A fun highlight is that you get to meet real live bryophytes that talk to the audience (see time 3:42). The costumes that the kids have are great and it is quite exciting to see young folks learning about bryophytes!
I did some more searching on YouTube and came across quite a number of video presentations used to communicate information about bryophytes. Here a couple for your educational-entertainment.
I really liked the part in this one where the water overflows from the antheridium dispersing the sperm to the egg. However I think that the part where thy have the spore production and dispersal is a little confusing. I am not sure exactly which concept they were trying to get across in that part.
