Students' introduction to high school science can take many forms. In some school districts, biology or Earth science may be a required before students can take physics or chemistry, while others make physics the foundation of the science education. Still other districts may require only that students earn a minimum number of science credits to graduate, but allow students (with their parents, teachers, and guidance counselors) to select which courses to take. We’d like to know how high school science instruction is structured at your school—and how you’d change if given the chance. Take NSTA’s Sequencing Science survey now!
