In my 5th grade science class my teacher had using cameras a lot to take pictures of nature. We would analyze and observe the pictures. We were also able to bring in pictures we took at home of nature and add it to our class nature gallery. I absolutely loved it!! I was always very excited to see the picture you brought in on display. Our teacher allowed us to write in our journals about observations we made from the pictures at free time or if we finished assignments early. She would also sometimes incorporate the nature gallery as part of science stations. My teacher would also use the pictures in writing. She would make up a sentence starter with one of the pictures and have us write a story.
I have attached websites that have different resources for ways to use photography in a classroom.
