I attended the Writing Biographies for Children breakout session at the 2013 SCBWI Summer Conference.
I loved their joy in their subject matter. I came away wanting to write a biography. Two days after the conference I woke up with a full blown idea for a Non Fiction picture book. How They Wrote It. I Googled the title and the idea because it was so clear to me that I couldn't believe anyone hadn't written it before. I've been researching and writing since last Tuesday and I have a first draft. That's a wonderful feeling.
I missed Michelle Markel's Sparkling Non Fiction Picture Books (Link is to her post about the event.) Golden Kite winner Jen Chase Ferris' Primary Sources! Out to Find The and How to Use them.
I also missed Andrea Davis Pinkney's workshops. Andrea is both an editor at Scholastic and an author. Here's the link to her breakout session, From Idea to Acquisition: Turning Your Brainstorm Into Books from the SCBWI Conference blog. I couldn't fined a report of her session - The Art and Craft of Non Fiction.
Just for fun, here is the GoodReads list Best Non Fiction Picture Books. Perhaps you would like t add to it.
