I love it when I stumble upon sites like this!!!
Project Noah help students experience nature through which they solve real-world problems. This site is for students to share their experiences with wildlife and they are given oppotunities to make a difference. Students make observations and investigations on key concepts in the Life Sciences and share their work with the Project Noah community.
Teachers can sign up and set up their classroom. Resources and teaching materials are available.
Great enquiry based curriculum and critical literacy.
There is an app available as well.
