This activity was interesting and it was able to cover a variety of different topics at the same time. All you need to participate is a device that can output picture/audio, paper, and a something to write with. The site does offer some printables, but if a printer is unavailable, the student can copy down the charts in a notebook. I really like how this resource breaks up the videos with discussion questions so that the students can stay engaged. The video quality of the different habitats was wonderful and they demonstrated how a biologist would use a field guide for identification. The bulk of the activity is listening to the calls of the frogs and being able to distinguish them. I did not get a chance to practice this sort of identification until college, so I was pleasantly surprised for them to introduce this concept to young students. A series of recordings are played and the students are asked to transcribe the sound into words they can later recall. The identification part was challenging, but I think you can turn it into a fun game by trying to mimic the sounds to help you remember. After identifying, the activity asks them to make observations of two ponds and compare the diversity of the different habitats. I really like how it makes students collect data and construct an explanation for why different species of frogs can co-exist in the same habitat. The extensions for this activity are thorough and I recommend looking into the Citizen Science project.
