This is a fun way to integrate non-fiction for Common Core! This science research was made to go with a 2nd/3rd grade class, but may be easily modified for other grades. Students research animals that are born from eggs such as snakes, birds, etc. Then they write clues (or a complete non-fiction writing if you'd like to extend it for upper grades). The students then read the clues to the class from broadest to most specific. The other students guess the animal. The student then "cracks" open their egg to reveal the surprise. Cute books mentioned to use with lesson as well. Enjoy!
