The University of the State of New York has designed a series of exams for high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety of styles,...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on the entire year's curriculum when they take this 13-page test.

Analyze nuclear fission chain reactions and how to prevent them as well as explore ways to control nuclear reactions through these simulations.

Start a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor.

Given diagrams, illustrations, symbols, or descriptions, student will distinguish between nuclear fusion and nuclear fission.

This lesson focuses on the formation and life cycle of stars. Stars form when enough dust and gas clump together because of gravitational forces. Nuclear reactions release energy to keep the star hot. Some stars grow larger over time....
