Camera to take pictures; paper, markers, stapler, glue to create book; print pictures on computer or take them to your local photo shop.
My daughter loves animals, and I thought this would be a fun way for her to combine her love of animals with learning about our part of the world. We took a camera and walked around our neighborhood, taking pictures of all the animals that we saw. We then printed them up, glued them to pieces of paper, and stapled the paper together to create a book. My daughter then helped me to write the name, date, and location of all the animals. My daughter has a kid-friendly camera, so she was able to take all the pictures herself. A disposable camera would work well, as would a Polaroid. Or mom or dad can take the pictures, as the grown-up helper. What would be really fun is to do this once a year to see how our animal environment is changing. Some alternate versions -- Go to the lake or park or beach and take pictures of the animals or plants. You could even create a map and mark the places on the map where the animals were found. For younger kids, take pictures of the animals in your house, even stuffed ones.
