This is great to use to investigate the three types of pollution. Students can go and explore pollution in their own environments and capture pictures of the three types. They may either capture examples using a camera or student-created pictures. As they capture or create pictures, they can create titles for each to put them in a photo journal or any other apparatus you see fit. This supports the standards S3CS1, S3CS4, S3CS8, S3L2 and RI.3.5. Enjoy!
