<p>Our district requires physical science in 9th, biology in 10th, and that's it. Kids on the college track take chemistry in 11th and physics in 12, although because of scheduling quirks sometimes they do it the other way around. Physical science is elementary physics and chemistry with a little tiny bit of weather and geology thrown in at the end. the honors class is quite good--DD is doing well in AP physics due to the foundation she got in honors physicial science as a freshman.</p>
