You can incorporate literature in many wonderful ways. Here are a few ideas:
-Fun and creative books that can go hand in hand with your science lessons. For example, if you are teaching the life cycle of a butterfly.. Try to find a book that can be used to get the students attention and can bring the idea full circle for them.
Book Idea: "The Amazing Life Cycle of Butterflies"
-Use fun poetry or songs found across literature that can come together with your lessons.
-Have students create a play or skit that has to do with a science book/science lesson.
-Have students write their own book concerning the lesson/activity.
Hope these help! Blessings,
