Maybe take some of the lapbook projects she has already created and glue them to a science board. Then whatever space is left she could write her own reports/narrations, make a timeline, research other area's etc...
I personally do not like most lapbooks because a lot of the time they take all the fun creativity out of it. Maybe if she made her own project board, she would regain an interest in it and get creative with it.
Just a thought.
