This is a unit that was created within a 1st Grade Science Interactive Notebook bundle. This is a stand alone unit you can use in your classroom. This was originally created with a 1st grade classroom in mind, but can easily be adapted for other grade levels. A thumbnail within the preview images gives you the TEKS covered, a listing of some of the activities and some samples of the activities. You can also purchase this as part of a bundle in my TPT store.
Let me know if you have any questions.
