This is an assessment I use to test my students' knowledge of the scientific tools and what they are used for. It consists of 9 matching questions and 4 multiple choice questions. Also, an answer key is included. It is geared for 3rd graders and meets Georgia Performance (GPS) standards for science. If your school uses the GA edition of the HarcourtÃ‚Â© science book, it goes with chapter 1.
