If you are looking for a meaningful way to include more Nature in your homeschool, take a look at Project Noah. I just love ideas like crowd-sourced research and citizen scientists – these are opportunities for you and your kids to do real research that will be used by scientists in their studies. In Project Noah, you can take pictures during your nature walk, post them and help scientists in their research of biodiversity. You can also see the pictures taken all over the world. Great for a Life Science unit or just Nature Study for all ages. Free.
