This site is more functional than the other two I posted. One of the unique features is its large collection. There are not only objects (photos or illustrations) but also materials/textures available. Another feature is that they have some pull-down menus to narrow down the search. We can select the images by the topic (animal, architectures, etc), dominant colors of the image we want, the number of items we want to see at once, etc. These functions meet the users' needs. The site also asks for donations of the images. The challenge might be the filter set by the districts. Almost all the time this is the case some teachers are discouraged. It is strongly recommended teachers check this site on a school computer before the intended use. If blocked, requesting unblocking may be the next thing to do. Furthermore, as a school or department it may be a good idea to secure several online repositories that are not blocked; therefore, any teachers can use at any time safely for educational purposes. Lesson Example: 3rd grade and above in Visual Arts Direction: In our life there are many signs. Common features of those signs are simplicity (restricted numbers of colors, shapes, lines, etc.) and clearness of a message (directly represented by an object). Suppose you are a professional illustrator and the city has asked you to create a symbol/sign useful to the community. Make sure to provide good reasons to back up your creation. (Ex. how your creation will promote the welfare of the city, reduce the crimes, or promote business, etc.) Search the needs of the city so that your creation is timely and meets the needs of the city. Save the resources. Image citation: Dario sign no baby carriages warning lift. (n.d.). Retrieved from http://www.imageafter.com/image.php?image=b17dario103.jpg

This site has a large pool of materials in multiple types: image (photos and illustrations), video, audio, etc. The stocked materials range from simple illustrations to more academic items. Teachers can use this site for newsletter handouts to lesson supplements. I chose a photo of a kachina doll for my lesson example. This may be inconvenient if the teacher needs to explain the details of the object of the photo. The site does not provide the details of the object of the photo. If this is the case, teachers may need to search the details in different venues and provide sufficient information. Example of 10th Language Arts lesson Direction: Teachers can show the photo (kachina doll) to class as they read Blue Highways by William Least Heat Moon. This resource is to provide assistance and add interests for readers. A group of students searches and finds two materials (either copyright free or copyrighted materials in multiple formats) that would add interests and help readers understand Blue Highways better. Each group shares two items with source information. Standard: ELACCL9-10SL (Speaking and Listening)5: make strategic use of digital media in presentation to enhance understanding of findings, and evidence and to ass interest. Image citation. Kachina doll. (2011). Retrieved from http://www.istockphoto.com/stock-photo-7810014-kachina-doll.php?st=170aa44

This is one of the best as a "copyright free" site for image files I found. The only restriction is that these items can not be contributed to other photo libraries (online or off line). The site is originally from England. There are several topics: animals, buildings, nature, places, technology, etc. All items are clear and appealing. (EX. Nature category has 92 pictures of mountains, rivers, flowers, plants, etc.) The file format is jpg with high resolution. A problem might occur when the image is linked to the URL or embedded because the website owner may delete or change the image at any time without notice. I recommend saving the image before using it. Lesson example: Science for 5th grade: 1. Direction: Examine the photo carefully and state how these stones were formed. What history do you see behind these stones? You need to observe the colors, shapes, and sizes of the stone. A group needs to gather knowledge learned in class and use it as evidence to support a group's decision. Resources are to be cited at the end of your paper. 2. Rubric: Final conclusion (2 points), Explanations and reasons well supporting the conclusion (5 points), Resources (texts or images used as evidence) (3 points) 3. Standard: S5CS6: Students will question scientific claims and arguments effectively.
