Study Edge Chemistry

In Chemistry, students will conduct laboratory and field investigations and make informed decisions using critical thinking and scientific problem solving. Students will study a variety of topics that include characteristics of matter, use of the Periodic Table, development of atomic theory and chemical bonding, chemical stoichiometry, gas laws, solution chemistry, thermochemistry, and nuclear chemistry. Students will investigate how chemistry is an integral part of our daily lives (TAC §112.35(b)(1)).
