High School Resources

Sci-ber Text is an online textbook that is based on the Utah Science Core Curriculum.

An introductory college-level chemistry course that explores topics such as atoms, compounds, and ions; chemical reactions and stoichiometry; ideal gases; chemical equilibrium; acids and bases; kinetics; thermodynamics; redox reactions and electrochemistry; and a whole lot more!

Did you know that everything is made out of chemicals? Chemistry is the study of matter: its composition, properties, and reactivity. This material roughly covers a first-year high school or college course, and a good understanding of algebra is helpful.

Learn AP Biology using videos, articles, and AP-aligned multiple choice question practice. Review the fundamentals of biochemistry, cell biology, genetics, evolution, and ecology, and develop scientific thinking skills as you explore the study of life.

Life is beautiful! From atoms to cells, from genes to proteins, from populations to ecosystems, biology is the study of the fascinating and intricate systems that make life possible. Dive in to learn more about the many branches of biology and why they are exciting and important.

An algebra-based, introductory college-level physics course that explores topics such as Newtonian mechanics (including rotational motion); work, energy, and power; mechanical waves and sound; and introductory simple circuits. This course is followed shortly after with AP®︎ Physics 2, which we also support.

Every student has the potential to change the world. Help them get started. #CSforGood
