Riya

Riya is a very useful tool for those who need to see something. They could make observations from pictures. For example, when covering ecosystems they could use some plants or trees to identify what ecosystem the picture is from. There are drawbacks. When the students look at this site they would have to be closely supervised. There are pictures that could be considered objectionable. There are better sites that could be used for projects like the one mentioned. The advantage of this site would be pictures are from people and there might be some pictures that are not available in all places.
