Student friendly search engines

I love Google.  Most people love Google.  Kids do too.  However, I discourage it's use with students at school because of the likelihood that students will get search results that contain inappropriate content, ads, and sites that do not contain reliable/accurate information.  In addition, most of the time students are faced with search results for sites where the reading level is too high.  I encourage students to use our school's library web page for resources that will yield search results with appropriate, reliable content at their reading level.  Here is the link for our library web page:

Here are a couple of search engines I encourage students to use over Google that are linked on our library web page.
