My son loves to watch Curious George, mostly because of the video clips after each of the animated shows. The clips are usually only 1-2 minutes but they show wonderful age appropriate science experiments. We have recreated many of the experiments throughout the years.
So I realize that suggesting you watch television with your child seems like a strange suggestion for a nature blog, but really I think this one is worth it! In fact, you don't really have to watch the whole show. If you go onto http://www.pbskids.org/ and click on Curious George then videos you will find over 80 different video clips on a wide variety of topics! Below is a link to the animal tracks video that we have recently enjoyed!
