Bioacoustics is a multidisciplinary field including biology, physics, electronics, engineering, computer science, data science, conservation & resources management. The study of animal sounds can serve as a fun tool for engaging in these scientific studies, and so may serve as a great way for educators to teach scientific topics that is naturally interesting to young students (equivalent to K-12 in U.S.).
What online resources are available for educators to use bioacoustics for one or more of these scientific disciplines? I'm looking for curriculum or educational activities (easy to adopt), not just information.
Please provide brief summary of age group, discipline, etc, to help others identify resources that might be appropriate for their need.
