Here are some extras I've used while doing WinterPromise's Animals and Their Worlds Program with a 3rd grader for his science program. Some weeks will have more extras than others. I will also add items as I come across them, even when we are finished with a week. Please also see below the listed weeks for extras I have come across that I haven't categorized.
Caution: I link to various websites and some online videos. The Internet changes daily and you may want to preview all sites and videos to make sure they are appropriate for your family.
If you have an extra you'd like to share, please email me!
I don't have the time to update the remaining weeks. Have fun with the rest of your year of study!
Here are some other resources I have come across though, that might be helpful:
The Camel -This is a very nice e-book with notebooking pages.
