www.wonderopolis.org. If you have never checked this site out, please do not delay. This site is maintained by six educators that attempt to answer the questions that many students, as well as adults, wonder about on a daily basis. They have subjects categorized for ease of searching as well as numerized for each wonder that has been answered. It also provides the opportunity for dicussion and feedback with each posted wonder. (The feedback portion may require some lessons in regards to digital citizenship and cyberbullying.) The authors provide answers using a voice with which students can relate, and would be appropriate for all elementary readers. This site may prove useful for your students that are reluctant readers, or for researching needs. The best part of it all...it is free!
I will be adding this site to the East Noble Symbaloo pages so that your students will have access to them.
