Begin each new science lesson by reading a picture book related to that lesson. For example, "The Tiny Seed" by Eric Carle can be used to introduce a lower elementary lesson on plants and "Cloudy with a Chance of Meatballs" by Judi Barrett can be used to introduce an upper elementary lesson on weather.
Assign a chapter book related to your science lesson for older students. For example, "A Single Shard" by Linda Sue Park demonstrates chemistry.
Encourage your students to make predictions about the lesson based on the books that you have read.
Instruct your students to keep a notebook for every science experiment you conduct in class. In the books, your students will write their predictions, observations and findings. Younger students who cannot write words yet can draw pictures.
Create a research project on a science topic. Take your students to the library and work with them on research skills as they work on their projects. For example, if you are teaching a lesson on the environment, you could assign a project for students to research different types of pollution.
