cute duck!
here is the write up from Free Technology site:
Duck Duck Go is a search engine designed with clarity and simplicity in mind. One of the ways that clarity and simplicity stands out is when you enter a search term that can have multiple meanings, Duck Duck Go alerts you to that and asks you what you really want to search for. For example, if you enter the search term "duck," Duck Duck Go will tell you that "duck" could be a noun or a verb. (see the screen capture below) Duck Duck Go also provides brief information summaries when you search for topics. This is handy if you're not really looking for a lot of information about a topic, but are just in need of a quick synopsis of a topic.
Here is the comic strip site I shared with you last night. I think it would work for any grade level and you have the ability to create a class gallery or save on disc.
The site was created in Australia and the company is dedicated to keeping this website "kid-friendly" and encourage you to contact them if you have any issues or concerns. I thought that was another nice feature.
Enjoy!
