Good lesson. It offers multiple UDL techniques with the websites, videos, podcasts, and writing. I like that it offers multiple means of assessment to provide kids with multiple learning styles options for proving they've learned the information. Concerns are whether the kids will be instructed on proper group behavior and roles and whether they will know how to start and write a blog. Also, you may want to add something about blogging on your objectives since blogging will be part of your assessments.
