April: Earth Appreciation Month!

April is here, and it's time for a new monthly theme! Now that spring is here and Earth Day is coming up, I'm going to highlight four great middle grade books that help readers appreciate this great planet. There will be a book about the land, one about the water, one about the air, and one about animals (although they all have lots of animals in them.) And, of course, there will be fun science activities, so keep checking back!

As usual, all comments this month (including comments on this post) will be entered to win their choice of our April earth books! (New followers get an automatic entry too.)

What are your favorite earth-friendly middle grade books? What are you looking forward to this month? Any suggestions for future monthly topics?

Added 12:13 pm: I forgot to add that the winner of the March giveaway (as chosen by random.org) is...Tasha! Tasha, let me know which of March's books you'd like, and whether you'd like a paper copy or an ecopy.
