This is a fun research activity for your kiddos. The links are all shortened to tinyurl links for ease of access.
Your kids will use a variety of websites to learn about and catalog information concerning dinosaurs. This is a great kick off for a research project on dinosaurs, or just as a learning activity.
I use this with my 3rd graders with no problems (other than the pronunciation of dinosaur names!), and it would be appropriate for 4th graders as well.
The teaching duration I have listed is really the amount of time it will take your students to get through this webquest.
I hope you enjoy this resource as much as I have!
