There is going to be a science fair at my school. I was wondering if anyone has any ideas on projects I could do that involve my rats. I also have two gerbils and one idea I have is to attach some sort of speedometer thing to their wheel to test their activity level in the day/night. So gerbil projects would be fine too. I did a maze with my hamster for a science fair two years ago but that didn't work very well because he mostly just climbed out and wasn't interested in the food but it would probably work better with the rats. Those are the only ideas I have so any more ideas would be great or just any experiences with science projects involving rodents.
