Most students learn how to Google things pretty quickly. When it comes to images we do need to be careful that they aren’t exposed to inappropriate materials as best we can. There are search engines that are built specifically for children, but I thought I would cover the Google features first as a starting point.
Search terms and SafeSearch
As a general rule the more specific your search terms (keywords) the better your results will be. However, even the most innocent of terms can return inappropriate material if SafeSearch is not turned on. Most browsers will activate it by default, but you should check that this is the case especially if the computer is used by others.
More search options
If you want a picture of cute cats for use in a certain project you can use the extra search options to include only certain images that match other criteria like the size, background colour etc.
