Are you looking for ideas and fun ways to get your first, second, or third graders writing about science? This post has lots of hands-on plant lessons and science experiments with writing activities to teach the life cycle of plants. The plant lapbook makes an ideal addition to your plant unit for 1st, 2nd, and 3rd grade. We displayed ours at open house and parents were so impressed! There are free posters for parts of a plant and photosynthesis in this post, too!
